Check valves are mainly used to hold a hydraulic cylinder in a certain position. A double-acting, pilot-operated check valve installed in the line between the hydraulic valve and the cylinder allows free flow in one direction and allows backflow only when pressure is applied to the pilot piston.
The hydraulic valve is connected to both central connections (V1 + V2). The hydraulic cylinder is connected to the outer connections (C1 + C2). The hydraulic cylinder can then only be moved when there is oil pressure from the valve.
Variant A is supplied with connections for 3mm hoses.
Variant B is supplied with connections for 4mm hoses.
The middle connections are connected to the Valve
The outer connections are connected to the cylinder.
The blocks with the outer hose connections can be mounted rotated in 90° steps.
