Foot Valve
Foot Valves are used to prevent back flow of the medium from the suction pipe of pumps; when the pump is turned off.
The valve disc is soft seated, which guarantees complete closure.
Due to its spring mechanism, closure of the valve is obtained before back flow reaches the valve, thereby minimizing the surge conditions.
As a result, Foot Valve operates in a fast way and closes silently.
Moreover, with the filter function, it prevents residuals from entering the pipeline and harming the pump or other crucial devices.
Foot Valve body is in globe design to minimize the head loss, and can be installed in vertical position with the direction of flow upwards.
Lift Type
Lift Check Valves has a disc that lifts up off its seat by higher inlet pressure. When the inlet pressure drops, the disc is closed before the back-flow reaches to the valve, enabling non-slam & drip tight closure.
It has a relatively short valve disc travel resulting in an immediate valve disc closing on no flow conditions, minimizing water hammer and surge conditions.
Lift Check Valve has a center-guided, spring loaded valve disc with a resilient seal, acting over a bronze or stainless steel removable valve seat.
It can be furnished with valve position indicator and electrical limit switches and can be serviced without being removed from the pipeline.
Silent Type
Silent Check Valves are designed to have drip tight sealing in case of back flow.
Moreover, the valve disc is soft seated, which guarantees complete closure.
Due to its spring mechanism, closure of the valve is obtained before back flow reaches the valve, thereby minimizing the surge conditions.
As a result, Silent Check Valve operates in a fast way and closes silently.
Silent Check Valve body is in globe design to minimize the head loss, and can be installed in any position, flow up or flow down.
Swing Type
Swing Type Check Valves are designed to have drip tight sealing in case of back flow.
The disc is opened in normal flow direction, providing laminar flow.
When there is a pressure change in the system and flow is coming back, the disc acts and closes the valve.
Accessories that enable slow or fast closing of the disc are available upon request.
