It is used in conjunction with an electronic batch control device such as the Daniel DL8000. The Model 788DVC valve is automatically controlled by the DanLoad for low flow start-up, high flow rate control, low flow shut-down, and final shut-off. It also provides for maximum flow meter accuracy by maintaining a constant flow rate in applications with varying line pressure. The Model 788DVC features an external pilot control loop that consists of a normally open solenoid pilot, a normally closed solenoid pilot, strainer and opening/closing speed controls. 1.1 Aggressive Products Some Daniel control valves have been equipped with an “AP” (Aggressive Products) cylinder assembly. This cylinder assembly may be supplied as a direct replacement for existing units or may be supplied with the original order. It is designed for all Daniel 2", 3", 4" and 6", 150/300 lb. ANSI, Series 700 Valves. Spring-loaded Teflon® cup-seals are utilized on the main body piston and low swell Nitrile O-rings in static positions. For specific instructions for receipt, installation and maintenance of Control Valves containing the “AP” Cylinder Assembly reference manual 3-9008554. Also contained within this manual are complete instructions for retrofitting existing standard valves with the “AP” Option package. If you have questions or need information not contained in this manual, please contact your Daniel sales representative or the Daniel Measurement and Control service center nearest you. INTRODUCTION 1-1 DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES D E C 2012 1.2 Principle of Operation Operation of the Model 788DVC Digital Control Valve is based on a balanced piston principle. When pressure on both sides of the main valve piston are equal, a spring (located on the top of the piston) acts as a differential force and closed the main valve piston. As pressure against the bottom of the piston increases and exceeds the pressure exerted against the top of the piston, plus the force of the spring, spring tension is overcome and the valve opens. Solenoid pilots are digitally controlled - full open or full closed - and are used to determine the main valve piston position required for flow control. Reference Figures 2-1, 2-2 and 2-3 for valve opening/closing positions. EQUIPMENT DAMAGE Read the entire recommended procedure for all installation operations and maintenance procedures before attempting to install or disassemble the valve. Disassembly of this cylinder assembly is different from previous Daniel Control Valves and requires strict adherence to the procedures outlined in this manual. Failure to read and comply with these procedures could result in damage to the equipment and compromise in the integrity of the operation. 1-2 INTRODUCTION DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES 2.0 D E C 2012 THEORY OF OPERATION The Model 700B Series Control Valve operates on a balanced-piston principle. When pressures on both sides of the piston are equalized, a spring located on top of the piston acts as a differential force and closes the piston. When the pressure against the bottom of the piston exceeds the pressure plus the force of the spring exerted against the top of the piston, spring tension is overcome, and the valve opens. See Figure 3-1 for more information. These valves are normally closed (N.C.) and they will open when both solenoids are energized. The valves are fail-safe as they close upon loss of power. They use the line product as the source of hydraulic power to open and close the main valve piston. An electrical supply controlled by an electronic preset is the source of power for energizing the two solenoids. These valves are used mainly for batching and they provide a means of reducing the rate of flow on on startup and before final shut-off of a predetermined delivery. This minimizes surges of pressure and line shock and assures ± 1/4 gallon shut-off (sizes 2 inch - 8 inch) of the preset volume. The total system generally consists of three pieces of equipment: (1) a flowmeter, (2) electronic preset with digital control, and (3) a digital electric control valve. The electronic preset is the device used to set the predetermined volume of liquid that is to be delivered by the valve. 2.1 Operational Sequence With both solenoids de-energized, the main valve is closed as shown in Figure 2-1. The main valve can be infinitely positioned anywhere between 0 - 100% open by digital control of the solenoids. With both solenoids energized, as shown in Figure 2-3, the valve begins to open. It will only open to the programmed flow rate set in the electronic preset. Normally, the electronic preset is programmed to digitally control low flow start-up, maximum flow rate, low flow rate before shut-off and no flow. The electronic preset will automatically energize and de-energize the solenoids to position the main valve to limit the required flow rate. When the required flow rate is reached, the solenoids will be as shown in Figure 2-2. This hydraulically locks the main valve piston in position. Should flow increase, the valve will close slightly to adjust to the required flow rate. All of the positioning is done by digitally controlling the two solenoids as shown in Figure 2-1, 2-2 and 2-3. THEORY OF OPERATION 2-1 D E C 2012 DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES CLOSED POSITION The normally closed solenoid is closed. The normally open solenoid is open. Y-port (P3) to Z-port (P2) is closed. X-port (P1) and Y-port (P3) pressures are balanced. The main valve spring being the differential force, closes the piston and keeps it seated. Figure 2-1. Closed Position 2-2 THEORY OF OPERATION DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES D E C 2012 OPEN - CONTROL POSITION The normally closed solenoid is closed. The normally open solenoid is closed. Y-Port (P3) to Z-port (P2) is closed. X-port (P1) to Y-port (P3) is closed. The product cannot flow to or from the top of the piston. The piston is hydraulically locked in position until the electronic preset commands the valve to open or close as required to maintain the desired high flow rate, or low flow rate. Figure 2-2. Open - Control Position THEORY OF OPERATION 2-3 D E C 2012 DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES OPEN POSITION - (no control) The normally closed solenoid is open. The normally open solenoid is closed. Y-port (P3) is open to Z-port (P2). X-port (P1) is closed off by the normally open solenoid. The pressure on the bottom of the piston (P1) is greater than the pressure at (P3) plus the spring force; (P1 minus P2) is equal to or greater than the spring force. Therefore, (P1) pressure pushes the piston open. No flow control is required. Figure 2-3.

After they intersect, continue reading pressure drop curve from curve A. In applications requiring a constant pressure drop over 40 psid a heavy main valve spring must be used. Curves A, B, C and D are based on water (specific gravity: 1.0). For liquids having a specific gravity of 0.8 or greater, multiply the pressure drop shown times the actual specific gravity. This results in the actual pressure drop. For specific gravities less than 0.8, use 0.8 to get the corrected pressure drop (curves B, C and D only). Figure 3-1.

The valve may be used with a variety of flow meter types, including Coriolis and turbine meters, as shown in Figure 4-1. In this installation the DL8000 is the primary batch and control device. Reference Figure 4-2 and 4-3 for configuration information. Flow must be horizontal or vertical up but never vertical down. 4.1 Recommended Installation Instructions As with all control valves, it is most important that proper installation be accomplished if the valve is to operate as designed. Preliminary set-up should include the following steps: 1. Evaluate the metering system in the process line to determine that criteria pertinent to digital valve control is met. • • • • Minimum meter K-factor: 20 pulses/unit Minimum meter pulse frequency (low flow): 50 Hz Minimum opening time (shut-off to full open): 1.5 seconds Minimum closing time (full open to shut-off): 1.5 seconds 2. Reference engineering drawings for proper in-line sequence of all components. 3. Check valve position. The inlet flange has been marked and is to be in the upstream position. 4. Verify all electrical connections against wiring diagrams and unit specifications. Reference Figure 4-3 for Control Valve configuration. INSTALLATION AND MAINTENANCE 4-1 DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES D E C 2012 EQUIPMENT DAMAGE It is recommended that the external pump control be turned to the OFF position when performing any electrical wiring installation and until initial control valve adjustments are made in the DL8000. Failure to comply with these procedures could result in damage to the equipment and compromise in the integrity of the operation. 5. Flush the line of any and all contaminates. 6. Bleed as much air as possible from the system before start up. 4.2 General Considerations as Applied to the DL8000 Upon completion of the preliminary installation of the Digital Control Valve a Start-up Adjustment Procedure must be administered. Reference “DL8000 Preset Controller Instruction Manual”, P/N D301244X012. 4-2 INSTALLATION AND MAINTENANCE DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES D E C 2012 The Daniel valve may be installed with a flow direction horizontal or vertical up but should never be installed with flow direction vertical down. When installed in a horizontal line, the valve should be installed so that the cylinder head is at the top of the valve and not the bottom. See below.

EQUIPMENT DAMAGE Read the entire recommended procedure for all installation operations and maintenance procedures before attempting to install or disassemble the valve. Disassembly of this cylinder assembly is different from previous Daniel Control Valves and requires strict adherence to the procedures outlined in this manual. Failure to read and comply with these procedures could result in damage to the equipment and compromise in the integrity of the operation. 5.1 Cylinder Assembly Removal - All Daniel Valves 1. Isolate the Control Valve from the system and bleed off pressure. 2. Loosen and remove the tubing from the cylinder head. 3. Remove the nuts securing the cylinder assembly within the valve body. 4. Tighten the two jack screws provided in the cylinder head until the cylinder assembly has been freed from the valve body. These screws should be tightened evenly to prevent damage to the cylinder O-ring and binding the cylinder assembly. 5. Remove the cylinder assembly from the valve body by pulling upward and evenly using both hands (on smaller valves) or a mechanical device (for larger models). 6. Remove the two jack screws from the cylinder head. DISASSEMBLY AND REASSEMBLY 5-1 DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES D E C 2012 5.2 Cylinder Disassembly Refer to Figure 5-2. PERSONAL INJURY AND/OR EQUIPMENT DAMAGE Caution is required when performing any disassembly procedure as the Cylinder head is bolted to a spring loaded cylinder assembly. Service should only be performed by trained and qualified service personnel. Failure to comply with recommended could result in serious injury and/or damage to the equipment. 1. Position the cylinder assembly in an arbor press with the cylinder head (5) down. Valves smaller than 6" may not require a press. Larger units may require the use of a spindle or arbor press to facilitate removal of the piston assembly, in which case, the arbor should be resting against the cylinder head. 2. Place a metal sleeve over the piston nose to protect the sense line during removal. This can be fabricated from a pipe section and should have an internal diameter large enough to encircle the piston nose. The length must be sufficient to accommodate complete spring compression with allowing the sense line to strike the press plunger. 3. Using EXTREME CAUTION depress the piston against the spring until the rectangular ports are cleared. Block the piston in the open position, fully compressed, by inserting a suitable wedge through the port opening. Any wood, nylon or non-marring dowel or handle that will safely guarantee piston position can be used for this operation. It is recommended that a brass or other soft metal bar be used for this operation. 4. Remove the retaining ring, sealing ring and O-ring. 5. Using EXTREME CAUTION depress the piston against the spring and remove the piston blocks. CAREFULLY remove the piston from the cylinder body while maintaining pressure on the valve spring. 5-2 DISASSEMBLY AND REASSEMBLY DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES 6. Lift off the cylinder head by taking out the socket screws. 7. Remove and inspect all O-rings for nicks, cuts and wear. D E C 2012 Figure 5-1.

Inspect all O-rings for wear and damage and replace as required. 2. If removed, attach the cylinder head to the main cylinder body. 3. Insert the valve spring into the cylinder housing. 4. Inspect and position the piston into the cylinder housing. 5. Insert the fabricated sleeve over the valve piston and spring assembly. Once fully compressed, block the spring following the procedure used in step 3 of the Disassembly procedure. 6. Inspect and reposition the seat O-ring. 7. Replace seating and retaining ring. Once the entire retaining ring is in its’ groove, position a punch or screwdriver over the end of the ring and tap sharply. This will seat the ring. 8. Again, using CAUTION, apply pressure to the valve piston and remove the block. Carefully relieve the tension on the spring until it is properly resting against the seat ring. 9. Reinstall the cylinder assembly in the valve body being careful to properly seat O-rings and secure in place using lock nuts. Figure 5-2.

DISASSEMBLY AND REASSEMBLY DANIELTM MODEL 788DVC DIGITAL CONTROL VALVES 6.0 D E C 2012 TROUBLESHOOTING The most frequent problem encountered with any control valve is the accumulation of sediment, rouge, scale and other foreign material in the pilot or its supply system. It is, therefore, good practice to periodically remove the pilot from the valve and inspect it for accumulation of these materials. The strainer and needle valve in the pilot supply line should also be flushed periodically to avoid erratic control and slow response typical to obstructed flow. If sub-standard conditions persist after thoroughly cleaning the system, examine the pilot for swollen o-rings. Periodic examination of all seal and o-rings for nicks, cuts and wear is recommended. Reference Section 5, Cylinder Disassembly/Reassembly.
