Two-way Cross-flow Relief Valve
Frequently Asked Questions
What is a Two-way Cross-flow Relief Valve?
A two-way cross-flow relief valve is a hydraulic control element that is mainly used to control the pressure of hydraulic actuators (such as hydraulic cylinders or hydraulic motors) to prevent overload or impact. It can provide overflow protection in both directions and allow oil to flow between each other within the set pressure range. It is commonly used in hydraulic motors or double-acting hydraulic cylinders.
What is the Function of a Two-way Cross-flow Relief Valve?
Overload protection: prevents damage to the hydraulic cylinder or hydraulic motor due to overload.
Prevent hydraulic shock: buffer the pressure shock during switching to avoid damage to the system.
Two-way pressure control: ensure that the pressure of the actuator in both directions is stable.
Energy recovery (partial design): Through cross-flow, sometimes some energy can be reused to improve system efficiency.
Typical Applications of Bidirectional Cross-flow Relief Valves?
Hydraulic motor drive systems (such as travel drives, motor drives)
Double-acting hydraulic cylinder systems (such as lifting and excavation equipment)
Wind turbine hydraulic control systems
Construction machinery (such as excavators, cranes, forklifts)
Injection molding machines, presses and other industrial equipment
