Suitable for most pumping applications including suction lift and low differential head. Booster pump control valves are installed in-line, directly downstream of the pump discharge.
Our pump control valves substantially reduce surges that occur when a pump starts or stops. ISC’s pump control valves are smart, they know when to open, when to close and they do it effortlessly. The pump control valve is normally closed and on pump start-up, a pilot solenoid is energized to open the valve, at a rate governed by the opening speed control. When shut-down is required the pilot solenoid on the valve is de-energized to commence closing. The pump is kept running while the valve slowly closes. When the valve is almost fully closed and flow is virtually zero, a stem mounted cam triggers the limit switch to stop the pump. In the event of a power failure, the built-in mechanical drop check closes immediately when the flow stops, independently of the valve position. Surges are minimized by closing the valve before reverse flow occurs.
