Product Specification

YN30V00120F1 YN30V00120F1 Root Pressure Relief Valve Control Valve Bypass Valve SK200-8 SK210-8 SK235 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with SK200-8 SK210-8 SK235 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 main relief valve, designed for SK200-8, SK210-8, and SK235 excavators, is a core pressure control plug-in valve within the distribution valve assembly. It is responsible for limiting the pressure of the entire hydraulic system and providing overload relief protection, directly determining the digging power of the entire machine and the working stability of the hydraulic system.

The valve body is machined from high-quality alloy steel and undergoes quenching and tempering heat treatment. It has high overall strength and is resistant to high pressure without deformation. The mating parts between the valve core and the valve sleeve are processed using ultra-precision grinding technology. The sealing surface of the valve port is hardened to resist the erosion of high-pressure oil and the wear caused by tiny impurities in the oil, significantly reducing the probability of valve port erosion and internal leakage increase. The internal core spring is made of high fatigue-resistant spring steel, which can withstand high-frequency pressure alternating impacts and is unlikely to show spring softening or elasticity decline during long-term operation. It is equipped with high-quality oil-resistant sealing components, which can withstand high-temperature immersion by hydraulic oil and effectively prevent leakage inside and outside the valve.
