Bell & Gossett V58046B Wafer Valve Automatic Flow-Limiting Valve - Manual

DESCRIPTION
The Bell & Gossett WAFER Valve is designed to fit between
two 150 lb. ASME flanges and to automatically control the
flow in a piping system to a selected preset flow requirement.
As pressure differential increases, a cartridge inside the valve
body reduces the flow area to accurately maintain the pre-
selected flow rate.
Operational Limits
Maximum Operating Temperature: 250ºF (121ºC)
Maximum Operating Pressure: 250 psig (1724 kPa)
Flow Control, Differential Pressure:
2 to 60 psig (14 to 414 kPa) nominal
INSTALLATION INSTRUCTIONS
1. For installing Wafer Valves:
a) Install the Wafer valve in the piping system/circuit
where it is desired to maintain the flow at a pre-
selected value. The lifting lug (eye-bolt) provided (from
4" thru 20") will make handling of the valve easier.
Install the lifting lug into the valve body. Install
between two identical 150 lb. ASME flanges. Use long
threaded rods to connect the two flanges together
and secure the wafer valve and mating gasket in full
contact with the flanges. Torque each nut on the
threaded rod to specified torque value necessary for
typical flange torque connections.
b) Install the unit so that the flow arrow on the body
housing points in the direction of flow.
