The RVVL series check valve is specially designed for line-mounting installations. It is characterized by high opening pressures and incredibly low pressure rise. This is reflected in the flat performance graph. The valve can be used as a preload valve. The spring-loaded
spherical poppet-type check valve is very robust, extremely leak-proof, and insensitive to contamination. The valve seat, poppet, and body are hardened. The properties of the sealing faces have been enhanced by precision mechanical processing. The valves prevent
flow in the screw-in direction (B to A) and open in the opposite direction. The check valve is supplied completely mounted in a hexagonal body. The valve is available in nominal sizes 04, 06, 08, 10, 16, 25, 32 and 40.
