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).

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.

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.

Duo-Chek Valves Duo-Chek high performance non-slam check valves are the original Mission wafer check valves introduced to the market in the late 50's. They are available in the sizes, pressure classes and configurations you need to meet the most demanding of applications. Our product range includes, but is not limited to, • Sizes: 2" to 72"
