Operation:

The electronic control valve is the dual solenoid, diaphragm actuated control valve.  

It is positioned by its two solenoid pilots (2) and (3).  

With pilot (2) closed and pilot (3) open, the diaphragm chamber of the main valve (1) in vented to downstream and the valve moves further open at an adjustable rate.  

Conversely, with pilot (2) open and pilot (3) closed, inlet pressure is applied to the main valve diaphragm chamber, moving the valve further closed at an adjustable rate.  

Finally, with both pilots closed, the diaphragm chamber is “hydraulically locked” (no flow on or off the chamber) and the valve holds its position.  

The electronic control valve can be ordered with normally open, or normally closed pilots.   In the event of failure, the valve will close, open or hold its last position depending on which failure position is specified.


Diaphragm actuated pressure relief/sustaining valves are used to protect systems from excessive over-pressure or to sustain a minimum upstream pressure.  The valve’s pilot system senses the upstream (inlet) pressure. As long as the upstream pressure is below the setting of the valve’s pilot the main valve is tightly closed.   When the inlet pressure rises above the setting of the valve’s pilot opens the main valve to allow flow into the downstream system (sustaining application) or to allow excess pressure to be discharged out of the system (relief application).  GA diaphragm actuated relief/sustaining valves can be supplied with solenoid shutoff and/or check function as well as other optional features.  

Electric Check Pump Control Valve

Flow Control Valves Differential Piston Actuated

​The Pressure Reducing Valve functions to reduce a higher upstream pressure to a lower, downstream pressure regardless of fluctuations in pressure or variations in flow. This rugged and versatile piston control valve provides superior design, simple operation, and maximum performance in water control. Maintains a constant downstream pressure despite fluctuations in demand and inlet pressure.

Meets American Iron and Steel requirements.​

​​Electric Check Pump Control Valves are installed on the discharge of a water pump to control surges associated with the starting and stopping of the pump. This rugged and versatile piston control valve provides superior design, simple operation, and maximum performance in water control. The development and proliferation of SCADA, CAN, Intranet, and Cellular systems has increased the requirement for electronically controlled valves that interface with these systems.  The Digital Control Valves were specifically designed for this task. While retaining the advantages of simplicity and line pressure operation, these valves offer an ease of operation and degrees of flexibility not previously achieved.
