P80 Two-way Hydraulic Control Check Valve 

Hydraulic Valves Description: A two-way hydraulic control check valve is a valve used to control the direction of liquid flow in a hydraulic system.  It has two connecting ports, one for entering the liquid and the other for exiting the liquid.  The valve has a piston inside that is pushed by pressure as the liquid flows in from the inlet, opening the valve and allowing the liquid to flow out.  When the direction of liquid flow reverses, the piston will be stopped by the reverse flow of liquid, thus closing the valve to prevent the liquid from flowing back.  This valve is suitable for hydraulic systems that need to control the direction of liquid flow to ensure the stable operation of the system.
