double counterbalance valve manufacturer in pakistan


Double counterbalance valves with in line body double counterbalance valves with in line body can be used in open center or closed center hydraulics systems, to control double direction overcenter motion.aluminium or steel valve body,different pilot pressure ratios and damping ways are available .flow rate from 2-250 l/min,max operating pressure 35 mpa(aluminum valve body 20 mpa)
Operation principle of counterbalance valve. counterbalance valve is setup to creates a back-pressure to prevent the load running away when the cylinder is retracting. these are basically relief valves but used in a particular application to set up a back-pressure in a circuit.
Polyhydron counterbalance valvebacked by a client-centric approach, we are acclaimed as a leading manufacturer and supplier of an outstanding range of polyhydron counterbalance valve. under the observation of our diligent experts, the provided valve is manufactured using
Understanding counterbalance valves. this valve can also be used with hydraulic motors and is then commonly called a brake valve. both counterbalance valves and pilot-operated check valves can be used to lock fluid in a cylinder to prevent drifting. however, a pilot-operated check valve cannot control an over-running load.

    Counterbalance valves with pilot assist are meant to control an overrunning load. the check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2.

    When liftinga load with a double-acting cylinder and a 9720 or 9721 valve in the systemthe return oil is checked at the 9720 or 9721 valve by an internal pilot operated check valve. if a hose(s) from the pump to the 9720 or 9721 valve is broken, the load will remain positively supported by this internal pilot operated check valve.

    Counterbalance valves. when the directional valve shifts, an overrunning load forces the actuator to move faster than pump flow can fill it. oil at high velocity leaves one end while the opposite side starves for fluid. a vacuum void forms in the inlet side of the actuator that must be filled before applying force.
