Throttle check valves SDRVM
The throttle check valve SDRMV consists of adjustable throttle valves SDM and check valves RVM (size G1/4), which are integrated in a valve block. Depending on the closing direction of the check valve is a throtteling of the flow in one direction and a low-loss flow through the check valve in the other direction. Herewith it is possible to set the speed of the cylinder or motor into the requested direction. The throttle check valve is located between a seated valve and the cylinder or motor.
