The DUAL PLATE WAFER CHECK valve LUG type covers the bolt along the entire length of the body. LUG type valves are supplied in scallop to keep the weight as low as possible, thereby minimizing the cost. LUG type valves are supplied with straight-through bores according to API-594. Note: 1.

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

check valves. Our products are manufactured and tested in accordance with respective API, ASME, and ANSI standards. Southern California Valve is a global leader in valve manufacturing for power, paper and pulp, oil and gas, and petro-chemical industries. SCV check valves have serviced critical backflow prevention applications for more than 40

A Ball Check Valve consists of a threaded or flanged body with internal features that guide a rubber‐coated ball in and out of the seat as the flow goes forward and reverse. The ball rolls during operation and has a tendency to clean itself. The valve's top access port provides ease of maintenance without removal of the valve from the line.

detectable flow is measured. range would be 16 to 20 psig (1.10 to 1.38 bar). Check valves Re-seal pressure is defined as the downstream pressure at which the having springs with rated crack pressures of 3 psig (0.21 bar) or check valve closes bubble-tight. less may require up to 4 psig (0.28 bar) back pressure to re-seal bubble-tight.

A check valve allows fluid flow only in one direction that's why it is called a one-way valve or non-return valve. Check Valve works on the principle of differential pressure. It means the check valve will only open if the upstream pressure is more than the downstream pressure.

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

Easy Riser® Swing Check Valve, trim, and associated equipment. Prior to installing the valve, thoroughly flush the water supply piping to verify that no foreign matter is present. The Easy Riser® Swing Check Valve may be installed in the vertical position with direction of flow up, or in the horizontal position with the access cover up. 1.

The Silent Check Valve was designed to open at approximately ¼ to ½ psi (2-3 kPa). This means that when a pump is shut down, a Silent Check Valve will completely close while there is still positive head on the inlet side of approximately ½ psi (3 kPa). In this simple manner reverse flow, which is a major cause of water hammer, is prevented.

Parker C Series Check Valves are designed for uni-directional flow control of fluids and gases in industries such as chemical processing, oil and gas production and transmission, pharmaceutical, pulp and paper, power and utilities.

Check valves with fixed cracking pressures, C, CP, and CH series, are cycled six times prior to testing . Every valve is tested to ensure it seals within 5 

your equipment is to have the right check valve for the job installed correctly. Mr. R. W. Zappe, in his book, Valve Selection Handbook, states that in general a compressor type check valve, such as the Hoerbiger Design, is a good choice for use in gas service. Depending on the flow conditions, the valve may be

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.
