Detail

HAWE HRP 7 V is a high-performance pilot-operated check valve, featuring reliable zero-leakage sealing and pre-unloading cushioning design. It serves as a core component for ensuring precise positioning and stable operation in high-pressure hydraulic systems. The valve enables one-way flow conduction and reliable reverse cut-off, and its reverse passage can be flexibly unlocked via an external control signal, achieving a perfect balance between locking safety and operational flexibility.

A core advantage of the HAWE HRP 7 V pilot-operated check valve lies in its zero-leakage performance in the closed state, which can accurately lock the position of hydraulic actuators and prevent displacement caused by system leakage or external interference. Its unique pre-unloading structure effectively suppresses pressure shocks under high-pressure and large-flow working conditions, enabling smoother valve port switching and significantly improving system stability and component service life. The independent oil discharge design optimizes the back pressure of the control piston, ensuring that the valve's response is not affected by fluctuations in return oil pressure for more precise operation.

With its stable performance, HAWE HRP 7 V is widely applied in construction machinery, providing reliable locking for the outrigger and boom circuits of cranes and excavators to prevent load falling. In metallurgical equipment, it maintains stable oil cylinder pressure for rolling mill screw-down systems and blast furnace equipment, ensuring production accuracy. It is also suitable for marine machinery, used for position locking of steering gear and windlass systems to withstand the impact of ocean waves.

In addition, it is applied in the mold clamping and ejection circuits of injection molding machinery, the supporting and pressure-holding systems of coal mine hydraulic supports, the positioning of tooling fixtures in automated production lines, as well as the key hydraulic circuits of aerospace. Relying on its safe and reliable locking and pressure-holding capacity, it meets the hydraulic control requirements of high pressure, heavy load and high precision in various industries.
