Production Details of the Check Valve RVP 30

The check valve type RVP 30 has the task of, preferably closing a flow leak free in one direction and to permit free flow in the opposite direction. 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.
