Hydraulically operated, pilot-controlled, pressure relief valve designed to maintain constant upstream pressure within close limits. This valve can be used for pressure relief, pressure sustaining, back pressure functions in a by-pass system. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to ...

Our pressure reducing valve is a hydraulically driven, pilot valve-controlled control valve. Automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. This valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. No matter how the flow rate or pressure ...

Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects. Water hammer refers to the high-pressure shock waves that occur when the flow of fluid abruptly stops (due to pump shut down or a valve disc quickly closing) in a piping system. When water hammer occurs, the resulting flow reversal places severe stress on the ...

The center line of the disc rotation is horizontally and vertically offset from the body seat. This high-performance designeliminates“seat set” compression while the valve is in the open position. Compression on the seal is released after only a few degrees of opening which reduces friction and wear. This makes the valve ideal for modulation or in the open position for extended ...
