Product Specification

GVO 21N-60-32211 Hydraulic Valve Pressure Relief Valve Safety Valve PC1250-7 PC1250-8 PC1250-11 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with PC1250-7 PC1250-8 PC1250-11 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 type of relief valve is specially designed for PC1250-7, PC1250-8, and PC1250-11 super-large mining excavators. It is the core pressure protection component on the main distribution valve. In mining operations, the impact load is extremely high. The relief valve is responsible for limiting the maximum pressure of the hydraulic system, achieving overload relief and discharging, quickly releasing the instantaneous high pressure in the circuit. It plays a crucial protective role for high-priced core components such as the main hydraulic pump, multi-way valve, rotation motor, and traveling motor, preventing damage to the components due to overpressure and ensuring the stable and safe operation of the entire hydraulic system. It is an essential hydraulic accessory for the maintenance of large mining excavators in mines.

The valve body is forged from high-strength alloy steel as a whole, and the valve core undergoes high-precision grinding and vacuum heat treatment. It has extremely high pressure resistance, impact resistance, and wear resistance. For the PC1250 series high-flow high-pressure hydraulic system, the clearance between the valve core and the valve sleeve is strictly controlled. It is equipped with high-pressure-resistant and anti-aging sealing components to minimize internal leakage of the valve and eliminate the problems of cross-pressure and oil leakage. It can adapt to high-load and harsh working conditions in open-pit mines and rock mining, resist the erosion of high-temperature hydraulic oil, withstand frequent alternating high-pressure impacts, and effectively extend the service life of the valve components, reducing the downtime losses of mining equipment.
