Throttle check valves - ZDZ1

Intended use: Throttle check valves are to be used in hydraulic systems in which they are responsible for throttling - in liquid flow in the check direction and free flow of the entire liquid output in flow in the opposite direction. Degree of throttling is adjusted smoothly (not by steps). Adjustment may be performed while valves are in operation. They may be installed on high pressure conduits in front of pressure receivers.
