GVO 60357922 Breaker Valve Pressure Relief Valve Hydraulic Safety Valve SY850 SY870 SY750 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with SY850 SY870 SY750  excavators, is a key pressure control valve in the hydraulic system. It regulates hydraulic pressure, releases overload pressure, protects core hydraulic components such as the main valve and hydraulic pump, and ensures stable operation of the entire machine.

This relief valve is precision-machined from high-quality steel and undergoes overall quenching treatment. Equipped with oil-resistant and high-pressure-resistant seals, it boasts excellent sealing performance, impact resistance, and wear resistance. Suitable for the high-pressure hydraulic conditions of excavators, it effectively prevents internal leakage, pressure loss, operational instability, and vibration.

Product Introduction

This plug-in type overflow valve is a dedicated pressure control valve for the excavator's distribution valve. It is responsible for limiting system pressure and providing overload protection. It has a standard plug-in specification, is easy to disassemble and maintain, and is an important safety component of the excavator's hydraulic system.

The valve body is machined from high-strength alloy steel and undergoes quenching and tempering heat treatment. The valve core is precisely ground and matched, and the sealing components are made of materials resistant to high pressure and aging. This effectively prevents internal leakage and external leakage. It adopts a threaded plug-in structure, which can be directly inserted into the main control valve's valve hole without the need for an additional valve body, thus saving internal space. It can stabilize the maximum system pressure, buffer the hydraulic shock caused by operations, protect the hydraulic pump, main control valve, and high-pressure oil pipe, and prevent components from being damaged due to overpressure. It is widely used in the maintenance and replacement of main control valves of large and medium-sized excavators.
