Check valves type RK/RB, RC, RE, and ER - HAWE Hydraulik - #1

Text version of the page

Check valves type RK/RB, RC, RE, and ER The check valves type RK, RB, RC, RE, and ER are used to block the flow in one direction and enable free flow in the opposite direction. The check valves type RK/RB are ball seated valves, where the valve element is spring loaded. They are sturdy and contamination tolerant due to their design. The screw-in check valves type RC may be installed in both directions with the spring loaded valve shim enabling rapid switching sequences. The screw-in check valves type RE is a shim type check valve also but without spring pre-load. This enables a very compact and simple method of blocking the oil flow in one direction. This valve can be used as a "foot valve" in the suction pipe of pumps. The mounting hole for all screw-in check valves can be easily machined with a standard drill (point angle 118°). The check valve inserts type ER feature a ball seated design and are commonly installed in the ports of ball seated directional valves or other manifold mounted valves.
