Product Specification

61029693 VZ02360-9599A Hydraulic Hold Valve Control Valve Balance Valve SY205 SY215 SY335 SY365 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with SY205 SY215 SY335 SY365 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 overflow valve is a pressure protection component specifically designed for the multi-channel hydraulic systems of SY205, SY215, SY335, and SY365 series excavators. It is a core pressure regulating safety element of the hydraulic system, responsible for limiting the maximum working pressure of the system, automatically discharging under overload conditions, and stabilizing the pressure of the circuit. It is a key component that ensures the smooth operation of various precision hydraulic components such as the main distribution valve, main hydraulic pump, and hydraulic cylinders of the excavator. 

In high-intensity operation scenarios such as earthwork excavation, rock crushing, heavy-load mining in mines, and infrastructure construction, when the excavation load suddenly increases and the hydraulic circuit pressure exceeds the preset safety threshold, this overflow valve can respond quickly and open, redirecting the excess hydraulic oil for backflow and pressure relief, effectively suppressing instantaneous high-pressure impacts and avoiding major faults such as pipe burst, pump body damage, and valve component deformation. It serves as a crucial barrier for establishing a solid and reliable pressure protection system for the entire hydraulic system of the excavator. 

The valve body installation holes, oil passage layout, and internal valve core assembly are precisely aligned with the structural dimensions, perfectly adapting to the SY205, SY215, SY335, and SY365 models. There is no need to modify the piping or installation base, and maintenance personnel can quickly complete disassembly, replacement, and installation, significantly reducing the downtime for equipment maintenance and effectively lowering the economic losses caused by project shutdowns. It is highly applicable for emergency repairs on construction sites or daily maintenance and replacement in repair shops.
