Description

Our pilot-operated check valves are leak-proof check valves with which the flow direction from B to A is open and the flow direction from A to B is normally blocked. If a hydraulic control pressure is applied to connection X, the pilot-operated check valve can be unlocked whereby the flow from A to B will also be opened. Connections A - B - X are sealed vis à vis each other in a leak-proof manner. The screw-in cartridge of the pilot-operated check valve is formed in a way that permits it to be screwed into a simple stepped bore. Technical data Pilot-operated check valves with ball cup – patented Screw-in model Permissible operating pressure: Viscosity range: 5 - 500 cSt Pressurising medium: hydraulic oil Installation position: optional
