Features:
▶ Subplate connection
▶ Leakage-free closure in one direction
Application:
The check valve RVP 25 is mainly used at the outlet of the pump as a back pressure valve and bypass valve.
The check valve type RVP 25 can be used in various high press industrial environment. It has the task of, preferably closing a flow leak free in one direction and to permit free flow in the opposite direction. The structure diagram is as follows. It basically comprises of the housing (1), poppet (2) compression spring (3),and spring seat(4). The stroke of the poppet (2), which is guided on its outside diameter,is limited by a mechanical stop. The built-in compression spring (3) supports the closing movement. Furthermore the compression spring(3) holds the poppet (2) in the closed position even when there is no flow through the valve.
