A adjustable valve allows liquid flowing unidirectional flow (V2 to C2). The reverse opening must be implemented through a pilot pressure control. One -way flow, the pilot piston is controlled by the pilot pressure, and the pressure of the overflow valve sets the pressure to control the reverse liquid flow.
These valve can lock the load without leakage, which is very suitable for many clamp function applications. It can also prevent the stall of the reverse load from falling in the case of the hose failure. For the decline load, because these valves can detect the real pressure of the load from beginning to end to avoid overload status, the operating state control function can be improved in most systems.
For a pair of hydraulic cylinders, a balanced hydraulic wrench can be used: the pilot pressure will first open the valve at the maximum load cylinder; so that the load pressure is transmitted to another oil cylinder, and these corresponding valves that are still in a closed state need to be compared to the original. You can turn on the pressure of a small pilot.
In order to obtain the best safety performance, the installation of these valves should be close to the actuator, which can be connected to both flange or installation through pipelines.
The function of the balance of hydraulic wrench module
A-unidirectional liquid flow through the one-way valve is used to improve the load.
B-When the switching of the valve does not work, or when the oil pump stops working, the oil return is cut back.
C-When the oil supply is exchanged to the valve, the pilot pressure is common to the balance of the hydraulic wrench to accurately control the opening size of the overflow valve, so as to achieve the purpose of accurately control the speed of the reduction. Balanced hydraulic wounds when trending overload have the same function.
D-When the load is inertia, the oil temperature rises, or the external force causes the pressure fluctuations, the hydraulic wrench is used for the use of the discharge valve (the main valve must be the median unloading).
