DFT® PDC® Check Valve (Pulse Dampening Check Valve) - Built for Reciprocating Compressors

Описание: https://industrial.dft-valves.com/pdc...
The DFT® model PDC® Check Valve is a pulse dampening check valve specially designed for use on the discharge side of reciprocating air or gas compressors. It is a flanged check valve that can be installed in either a vertical or horizontal orientation. The PDC contains a pulse dampening chamber which helps main­tain the open disc position during intermediate pressure drops (pressure pulses) due to the reciprocating action of the pump. The PDC® check valve is available in sizes up to 26” line size, class 1500 from DFT Inc.

Compressors – especially reciprocating compres­sors – can generate pressure pulsation in a system. Pulsation occurs due to the intermittent drops in pressure between the upstroke and down stroke of the reciprocating motion. This results in shaking or vibration within the system (similar to hammering) which can cause accel­erated wear on the valves, piping, and fittings. Wear of compressor components can ultimately lead to gas leakage and subsequent reduction in output pressures through the piping system. Specify DFT’s model PDC for superior protection of your compressors.
