FLANGED VALVES The DFT® Model PDC Check Valve. is a silent, non-slam check valve specially designed for use on the discharge side of reciprocating air or gas compressors. It includes a pulse-damping chamber to maintain the disc in the open position during the momentary reductions in flow associated with each cycle of a reciprocating

Ball Check Valves are simple and compact and commonly used on small water or wastewater pumps where economy is important. A Ball Check. Valve consists of a

ZRK-ZRKF-swing check valves are designed to block media on one side of the pipe within allowable pressure and temperature limits (see data sheet) and to be installed in a pipe system only. They are only to be used with media, which the material and the seals are resistant to. They are not suitable for media with solid components.

valves are typically used in controlling the rate of decompression in a large press before shifting the main valve. Pilot operated valves, like direct operated valves, permit free flow in one direction and prevent flow in the reverse direction. However, pilot operated valves permit reverse flow when a pilot pressure signal is applied to the

5CK120 - Check Valve Pilot-to-close, ball type 120 L/min (32 USgpm) • 350 bar (5000 psi) Sectional View Description Pilot to close check valves allow flow to pass in one direc- tion, with a low pressure drop to prevent reverse flow. When the pilot pressure is applied, flow is prevented in either direction.
