Use And Operation
Counterbalance Valve are used to control actuator's movements and block in bothdirections in order to have a under control descent of a load; load's weight doesn't carry it away, as the valve prevents any cavitations of the actuator.This valve is ideal when normal overcentre valves doesn't work properlyas it's not sensitive to back pressure. They allow to work in series with more movements.Haohong Hydraulic also has MONOBLOCK CONTROL VALVES and Pressure Relief Valves.
Overcenter valves are used where there is vital importance in the system. VBCD DE FL series are used to control actuator’s movement and block in both directions. Pressure is adjustable and sensitive. They can be used on crane booms and can easily mounted on cylinder with flanged ports.
