The Model 770-55-U Flow Control Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that maintains preset maximum flow, regardless of fluctuating demand or varying system pressure. The valve opens and shuts off in response to an electric signal.
Model 770-55-U

Typical Product Applications
Parallel Valve Installation
In a distribution network, there is often a need to respond to several flow regimes. In flow control valves, the orifice limits the valve adjustment range to about ±15%. Parallel installation of two Model 770-55-U valves enable:
- Flow limiting for various flow regimes
- Equalizing operating hours between valves
