Type 92W Instruction Manual Form 5237 February 2009 Type 92W Liquid Regulator Introduction Scope of the Manual This instruction manual provides installation, maintenance, and parts ordering information for the Type 92W liquid pressure-reducing regulator, which includes the Type 6492H or 6492L pilot. Accessories used with this regulator, including any pressure-loading device for a Type 6492H or 6492L pilot with tapped spring case, are covered in other manuals for those accessories. W4086-3 NPS 1, NPT STEEL MAIN VALVE WITH TYPE 6492H PILOT Product Description The Type 92W pressure-reducing regulator for liquid service includes either a Type 6492H or a Type 6492L pilot (Figure 1). Both pilots have a friction-reducing bellows seal on the stem. They offer precise pressure-setting adjustment plus high sensitivity to downstream pressure changes. These pilots are available in either a standard version with a drilled spring case vent, or an optional version with a tapped spring case vent and a sealed adjusting screw for pressure-loading service. A Fisher® 67 or 1301 Series regulator or a 670 Series panel-mounted regulator may be used to load the pilot of a version for pressure-loading service. Specifications Specifications for the Type 92W regulator are found in the Specifications section. W4088-1 NPS 3 (DN 80), FLANGED CAST IRON MAIN VALVE WITH TYPE 6492L PILOT Installation Figure 1.

The pressure/temperature limits in this Instruction Manual, or any applicable code or standard limitations, must not be exceeded. To avoid such injury or damage, provide pressure-relieving or pressure-limiting devices to prevent service conditions from exceeding those limits. Additionally, the pilot could be broken off the main valve by physical damage, causing personal injury and property damage due to escaping liquid. To avoid such injury and damage, install the regulator in a safe location where it is protected from physical damage. 2 caution Liquid pressure control systems should be designed using good engineering practices to eliminate quick starting or stopping of the flow stream, which can produce water hammer. . 1. Only personnel qualified through training and experience should install, operate, and maintain a Type 92W regulator. Before installation, make sure that there is no damage to, or debris in, the regulator. Also make sure that all tubing and piping are clean and unobstructed. Type 92W Table 1.

A Type 92W regulator may be installed in any orientation, as long as flow through the regulator matches the direction of the arrow on the main valve body. 3. Apply liquid-compatible pipe compound to the male pipeline threads for an NPT body, or use suitable line gaskets for a flanged body. Use acceptable piping procedures when installing the regulator. . 4. If continuous operation of the system is required during inspection and maintenance, install a three-valve bypass around the regulator. If the flowing medium contains solids, install a properly sized strainer upstream of the regulator. Note A regulator that has the Type 6492H or 6492L pilot with a 1/8-inch (3,2 mm) drilled hole in the spring case may function improperly if this spring case vent hole becomes clogged. Install and maintain such regulator so that the spring case vent hole stays clear. 5. As shown in Figure 2, connect a control line as large as possible but no smaller than 3/8-inch (9,5 mm) diameter bushed down to the 1/4 NPT connection in the cylinder spacer (NPS 1, 1-1/2, or 2 body size) (DN 25, 40, or 50) or the pilot body (NPS 2-1/2, 3, or 4 body size) (DN 65, 80, or 100). With the NPS 2-1/2, 3, or 4 (DN 65, 80, or 100 body size, the pilot may be mounted as shown in Figure 6 so that the control line connection faces either upstream or downstream. 7. Do not locate the control line connection in a gate, plug, or check valve; or in an elbow, swage, or other area of the pipeline where turbulence or abnormal velocities may occur; or in a large-volume vessel that can cause noticeable control lag. 8. Install a shutoff valve (not a needle valve) in the control line to isolate the pilot during maintenance. 9. Install a pressure gauge in the control line, or near the regulator, to aid in setting the outlet pressure. 10. With a pressure-loaded or on-off pilot, connect the pressure-loading or on-off piping or tubing to the 1/4 NPT connection in the tapped pilot spring case. 11. The pressure setting of the regulator is determined by: • The pilot control spring adjustment on a standard pilot, or . • The pressure-loading device in conjunction with the control spring adjustment on a pressure-loaded pilot. In both cases, check these settings to make sure they are correct for the application. Startup and Adjustment Note The maximum inlet pressure for a specific construction is stamped on the main valve nameplate. Use pressure gauges to monitor upstream and downstream pressures during startup. . 6. Locate the control line connection at least 10 pipe diameters away from the regulator or swage and in a section of straight pipe. . 3 Type 92W air loading regulator control line connection needle valve control line shutoff valve bleed restriction (required only if the loading regulator does not have internal relief) control line connection control line shut off valve strainer strainer block valves block valve vent valve block valves bypass line block valve vent valve bypass line 16A7958-B A2607-1 16A7958-B 16A1547-A A3334 with standard pilot WITH PRESSURE-LOADED PILOT Figure 2. Typical Installations Adjustment On a regulator with a standard or pressure-loaded Type 6492H or 6492L pilot, loosen the hex nut (key 16, Figure 4). Turn the adjusting screw (key 15, Figure 4) into the spring case to increase the downstream pressure. Turn the adjusting screw out of the spring case to decrease the downstream pressure. When the required downstream pressure is maintained for several minutes, tighten the hex nut to lock the adjusting screw in position. On a regulator with a pressure-loaded Type 6492H or 6492L pilot, also refer to the instruction manual of the pressure-loading device for downstream pressure adjustment procedures. Make sure that the combined pilot control spring setting pressure and spring case loading pressure does not exceed 150 psig (10,3 bar) for the Type 6492H pilot or 25 psig (1,7 bar) for the Type 6492L pilot. For example, combining a 5 psig (0,34 bar) spring setting pressure and a 10 psig (0,69 bar) spring case loading pressure results in a regulator pressure of 15 psig (1,0 bar). Startup with New Regulator Installation 1. Remove all pilot control spring compression by turning the adjusting screw out of the spring case according to the adjustment procedure. 2. Slowly open the upstream block valve. 4. Open the control line shutoff valve. . 6. Perform the adjustment procedure until the downstream pressure reaches the desired setting. 4 1. Open the upstream and downstream block valves and let the regulator take over control at the existing pilot control spring setting. . 2. If a bypass line is used, slowly control the bypass line block valve. . Shutdown 1. If a bypass line is used, slowly open the bypass line block valve while monitoring the downstream pressure. 2. Close the control line shutoff valve. 3. Close the downstream block valve. 4. Close the upstream block valve. 5. If a pressure-loaded or on-off pilot is used, close the needle valve to the pilot. . 6. Vent the regulator and control line to release any trapped pressure. Principle of Operation Pilot supply pressure is piped from the main valve inlet (Figure 3) to the pilot inlet connection. Downstream pressure registers on the main valve pistons through the downstream control line and then on the pilot diaphragm. 3. Open the downstream block valve. 5. If a bypass is used, slowly close the bypass line block valve. Startup with Existing Regulator Installation After Normal Shutdown When increased downstream demand lowers the downstream pressure to a value below the setting of the pilot control spring, this spring forces the pilot valve plug open to increase the loading pressure on the main valve Type 92W Type 92S August 2007 Type 92S Self-Powered Control Valve Type 92S September 2006 A6553 Type 92S 2-1/2 thru 6 x 4-Inch (DN 65 thru 150 x 100) inlet pressure inlet pressure OUTLET pressure OUTLET pressure ATMOSPHERIC pressure ATMOSPHERIC pressure LOADING pressure LOADING pressure A6552 A6553 Type 92W with Type 6492L Pilot NPS 1 THROUGH 2 (DN 25 THROUGH 50) MAIN VALVE Type 92W with Type 6492H Pilot NPS 2-1/2 THROUGH 6 X 4 (DN 65 THROUGH 150 X 100) MAIN VALVE Figure 3. Operational Schematics pistons. At the same time, the increased demand lowers the downstream pressure on the main valve piston(s). This opens the main valve plug, increasing flow to the downstream system to satisfy the increased demand and to restore downstream pressure to the setting of the pilot control spring. Decreased downstream demand increases the downstream pressure registered on the pilot diaphragm. The increased pressure overcomes the force of the pilot control spring and allows the pilot valve plug spring to close the pilot valve plug. As the pilot valve plug closes, excess loading pressure bleeds to the downstream system through the pilot bleed restriction. At the same time, decreased downstream demand increases the downstream pressure registered on the main valve piston(s). This allows the main valve spring to close the main valve plug, reducing flow to the downstream system in response to the decreased demand. With a pressure-loaded or on-off pilot, the operation is the same as for a standard pilot except that the pilot control spring force on the pilot valve plug is aided by pneumatic pressure from the loading device or solenoid valve. Maintenance Regulator parts are subject to normal wear and must be inspected periodically and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions and upon applicable codes and government regulations. ! Warning Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting to disassemble: • Isolate the regulator from the process, • Release process pressure, and . • Vent the pilot supply and main valve loading pressures. . Types 6492H and 6492L Pilots These procedures are to be performed if inspecting, cleaning, or replacing any pilot parts, or if cycling, erratic control, or too high or too low an outlet (control) pressure is noted. Perform only those procedures in this section required to correct the problem. Key numbers refer to Figure 4 unless otherwise noted. Note Before performing any maintenance, loosen the hex nut (key 16), if used, and turn the adjusting screw (key 15) counterclockwise until all compression is removed from the control spring (key 12). Remove the pilot from the pipe nipple and connectors (keys 82 and 83, Figure 6). . 5 Type 92W 1. Unscrew the plug guide (key 2).

All key numbers are referenced in Figure 5 except where otherwise indicated. Instructions are given for complete disassembly and assembly. Disassemble the main valve only as far as necessary to complete the required maintenance. Then, begin the assembly procedure at the appropriate step. . Note The regulator may remain in the pipeline during maintenance procedures unless the main valve body is replaced or removed for repairs. . Whenever a gasket seal is disturbed by removing or shifting gasketed parts, a new gasket should be installed upon reassembly. This is necessary to ensure a good gasket seal. . Disassembly 1. Disconnect all tubing and remove the pilot from the main valve. . 2. Remove the cap screws (key 3, not shown) from a cast iron body, or stud nuts (key 4) from a steel body, and lift off the body flange. 3. For the NPS 1, 1-1/2, and 2 sizes (DN 25, 40, and 50), remove the top cylinder (key 17), and pull out the top piston with attached stem and other parts.
