Product Specification

84327668 51650-16 Pressure Relief Valve Control Valve Hydraulic Safety Valve Case H30 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with Case H30 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 threaded cartridge relief valve is an important pressure control component of the hydraulic system of excavators. It adopts a standard cartridge structure and is used for pressure limiting and overload protection of the system. The installation and replacement are simple, and it is compatible with multiple hydraulic main circuits and branch circuits of excavators. 

The valve body is made of high-strength alloy steel and undergoes heat treatment and precise machining. The valve core is precisely ground for high precision fit. The sealing components are resistant to high pressure and oil corrosion, effectively controlling internal leakage. The threaded cartridge structure is directly installed in the valve hole, without the need for an additional valve body, saving installation space. It can stabilize the system pressure, absorb oil circuit shock, protect hydraulic pumps, distribution valves, and high-pressure pipelines, reducing damage to hydraulic components caused by overpressure, and is widely used in the maintenance and replacement of hydraulic circuits of small and medium-sized excavators, wheel excavators, and construction machinery.
