XKAY-00976 Rotating Motor Relief Valve Hydraulic Safety Valve Control Valve R210VS R220VS R225VS R300VS R330VS Excavator Parts

Product Description

The GVO excavator relief valve, compatible with R210VS R220VS R225VS R300VS R330VS 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 rotary relief valve, designed for the R210VS, R220VS, R225VS, R300VS, and R330VS series of excavators, is the core cartridge-type pressure protection component of the hydraulic system for the rotary motors of the VS series machines. It is directly installed inside the valve chamber of the rotary motor and is mainly responsible for pressure limitation in the rotary circuit, overload relief, and rotary braking buffering operations.

The valve body is forged from high-toughness alloy steel and undergoes a complete quenching and tempering heat treatment process. The overall structural strength is high, and it has excellent resistance to high pressure and impact. It can withstand the continuous testing of the alternating high pressure conditions of the VS series machines for a long time. The working surface of the valve core and valve sleeve is treated with high-precision mirror grinding, and the sealing position of the valve orifice is hardened and strengthened. Combined with anti-aging and high-pressure sealing rubber rings, even when exposed to a long-term high-temperature hydraulic oil environment, it can stably maintain the sealing performance, reducing the occurrence of internal leakage and external leakage faults in the valve components. The flow channels of the valve group have been optimized through flow simulation, resulting in a sensitive pressure relief response, crisp opening and closing actions, and no common problems such as valve core jamming, pressure adjustment drift, or pressure relief lag.
