Double Check Valves with Hydraulic Operation
A check valve is the simplest type of directional control valve used in hydraulic systems. Check valves stop the flow of fluid in one direction and allow free flow in the opposite direction. They are also known as non-return valves. They are used to block pressure spikes, prevent oil lines from draining and block oil flow from the accumulators.

These valves are used to block the cylinder in both directions. Flow is free in one direction and blocked in the reverse direction until pilot pressure is applied. They are used on double acting cylinders. These valves can be assembled directly on cylinder with flangeable surface.
Port sizes: From BSP 1/4’’ to BSP 3/4’’
Max. flow: From 20 litre/min up to 100 litre/min
Max. pressure: From 300 bar up to 350 bar
