CHECK VALVE 7/8 3122/7 CASTEL KM113 Forged brass check valve: Model: 3122/7 Connection ODS: 7/8 Kvm3/h value: 6.6 Min. (bar): 0.1
The check valve is a device that allows the circulation of the fluid in a single direction within a piping or a conduit, which is why it is important to check the correspondence between the direction of the flow inside the piping and the direction indicated by the arrow on the valve body. This type of valve can be installed in all the branches of a refrigeration system when it is necessary to avoid the undesirable consequences of reversals of the flow direction, in accordance with the limits of use and the established performance.
The check valve is made up of an element linked by a guide which, through the action of a spring, is pushed against the valve base when the pressure to open the valve is insufficient. On the contrary, if sufficient positive pressure is given, the check valve will open allowing the passage of fluid.
Castel offers different types of check valves, among others, hermetic and removable.
