The SV291 through SV295 Series valves are 2-way, pilot operated, anti-water hammer, and normally open. These valves are designed to reduce or control water hammer, which typically occurs with in-compressible fluids when the closing of a valve creates a sudden change of the fluid velocity. Restriction of the pilot flow in these valves will prevent them from slamming closed. Valve and piping system life is enhanced since the noise, vibration, and shock of water hammer are reduced.
Where small flows (CV <3.0) at relatively low pressure differentials are present, the water hammer is eliminated by the fixed restriction of the pilot flow. This is the standard design for the industry. However, to reduce water hammer in high flow applications, a unique field adjustment device can effectively control the water hammer in an application. The closing time on these valves can be adjusted by a 4-position selector. Position 1 allows the fastest closing, position 4 the slowest.
TYPICAL APPLICATIONS:
Water Treatment, Irrigation, Cooling, Car Washing Equipment, Petroleum Processing, Dish and Bottle Washing
