APPLICATIONS:

The pilot operated check valves allow free flow in a direction (with low pressure drops)and stop it in the opposite direction until they are opened by the pilot pressure(coming from the other line of the circuit).

APPLICATIONS:

Under pressure so that the fluid flow from the V to C, and the flow from C to V and blocked in the reverse direction.

 

 

APPLICATIONS:
The overcenter valves are employed to control the block and the motion of an actuators in one direction(single overcenter valves)or in both the directions(dual overcenter valves)

 

 

 

APPLICATIONS:
The shuttle valve is equivalent to two check valve Combination valve,and its role is equivalent to "OR gate".There are 3 Ways valves,  which detect the higher pressure signal between 2 input signal.

 

 

APPLICATIONS:
Connect circuit port with pressure to P and tank port to T.Port P is reversible.
The circuit is used to control flow and pressure.
