WROPOL ENGINEERING - Controlled check valves

Intended use: Controlled check valves with ZST hydraulic control are to be used in open hydraulic systems in which it is necessary to close the flow from receiver to sink with a possibility to control this flow. ZSZ valves can be installed on a hydraulic installation conduit. Position of installed valve in space can be chosen arbitrarily.
