Circuit Setter

Calibrated Balance Valves

with Flanged Connections

DESCRIPTION

The Bell & Gossett Circuit Setter calibrated balance valve is a

precision machined triple purpose balancing instrument. It is precisely

calibrated for use as a presettable balance valve, variable orifice flow

meter and positive shut-off service valve.

Valves are furnished with a calibrated nameplate and memory stop

indicator which permits the value to be preset to a fixed open position

and then closed for service without disturbing valve setting.

Valves are equipped with capped readout valves fitted with internal

check valves. Sizes 2-1/2"-

4" (brass ball) include a 1/4" NPT tapped

and plugged drain port as standard.

MAXIMUM OPERATING TEMPERATURE

250°F (121°C)

MAXIMUM WORKING PRESSURE

175 PSIG (1207 kPa)

TYPICAL SPECIFICATION

Furnish and install as shown on plans and with manufacturer's

recommendations Model CB calibrated balance valves.

PRE-SET BALANCE FEATURE

Valves to be designed to allow installing contractor to pre-

set balance

points for proportional system balance prior to system start-

up in

accordance with pre-set balance schedule.

VALVE DESIGN AND CONSTRUCTION

Valves shall be of heavy-

duty cast iron {flanged} construction with 125

psi ANSI flange _____ connections suitable up to 175 psi working

pressure. Valves 2-1/2" -

4" pipe shall have a brass ball with glass and

carbon filled TFE seat rings. valves 4" -

12" shall be fitted with a

bronze seat, replaceable bronze disc with EPDM seal insert, and

stainless steel stem.

DESIGN PRESSURE/TEMPERATURE

IMPORTANT

When monitoring system flow care must be exercised to avoid

direct skin or eye contact with liquids that may escape. Liquids

with temperatures in excess of 120°F (49°C) may cause burns.

Bell & Gossett Circuit Setter Balance Valves are not

recommended for use with meter connections pointing downward.

To retain calibrated accuracy, a minimum length of unrestricted

straight pipe adjacent to the valve should be maintained as

follows:

SIZE

INCHES (mm)

UPSTREAM "A"

(In Pipe Diameters)

DOWNSTREAM "B"

(In Pipe Diameters)

2-1/2"-4"

(63.5-101.6) 3 1

4"-12"

(63.5-304.8) 5 2

Best use results maximize straight pipe length entering and

leaving valve. Obstructions or changes in planar flow profiles

entering valve may affect accuracy if too close to valve.
