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.

Series C check valves permit free flow in one direction, and dependable shut-off in the reverse direction. Operation When pressure going through the valve is increased to the cracking level, the valve opens. When the pressure is reduced to below the cracking level, the valve closes. Features • Stainless steel poppets standard.

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.

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.

A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of

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. For more information contact the company.

Nov 11,  · As mentioned above, a check valve, also called a non-return valve, reflux valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in one

Series C check valves permit free flow in one direction, and dependable shut-off in the reverse direction. Operation When pressure going through the valve is increased to the cracking level, the valve opens. When the pressure is reduced to below the cracking level, the valve closes. Features • Stainless steel poppets standard.

Re-seal pressure is defined as the downstream pressure at which the check valve closes bubble-tight. Example: For a valve with a spring having a rated cracking pressure of 25 psig (1.72 bar), the actual cracking pressure ranges between 20 and 30 psig (1.38 and 2.07 bar). The re-seal pressure range would be 16 to 20 psig (1.10 to 1.38 bar).

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.

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.

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.
