AWP Stop check valve RVAK
Check valves with a rising stem with a PTFE ring seal on the stem stop, with regulating cone.
AWP stop check valves are automatically activated locking units. They are opened by the pressure exerted by the working medium upon the valve plate. As soon as the flow is interrupted or the flow direction is reversed, the valve locks automatically. It can also be locked manually with the rising stem by using the handwheel. The built-in damping device makes this type especially suitable in cases where the power requirement varies significantly.AWP stop check valves are suitable for installation in the refrigerant cycles of industrial refrigeration systems. They are installed on the pressure or suction side of compressors, or in pipes for which only one direction of flow is permitted. AWP stop check valves are maintenance-free. Any defects that occur in the functional performance of the valves can be repaired.
