G1/2 90LPM Hydraulic Bidirectional Tubular Balance Valve

Pressure Counterbalance Valves Description:

The balance valve, also known as the speed limit lock, is a pressure valve used to control and adjust the system pressure, which is based on the principle of balancing the liquid pressure on the spool and the spring force.

These Over Centre Valves are used to control the actuator movements and block it in both directions. In order to have the descent of a load under control and avoid the load's weight being carried away the valve will prevent any cavitation of the actuator. Type "A" is different due to the connection positions and the pilot ratio.

Working principle: The anti-regulation in the valve body automatically reduces the diameter when the pressure at the entrance increases, reducing the change in flow rate, and vice versa. If it's reversed, the system won't work. And the regulating valve plate is directional, and the reverse pressure can even reduce or even close the flow rate; The balance valve belongs to the regulating valve category. By changing the gap between the valve core and the seat (that is, the opening degree), the flow resistance of the fluid flowing through the valve is changed to achieve the purpose of regulating the flow rate. The balance valve is equivalent to a throttling element whose local resistance can be changed for an incompressible fluid, as determined by the flow equation.
