JA0F1003 XKAY-00603 401-00307B Rotary Motor Relief Valve Safety Valve Pressure Relief Valve DH60-7 R60-7 SY75 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with DH60-7 R60-7 SY75 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 plug-in type overflow valve is a key hydraulic safety component specifically designed for the distribution valves of DH60-7, R60-7, and SY75 excavators. It plays a crucial role in the hydraulic circuit of the entire machine, serving to limit system pressure, release overload pressure, and stabilize pressure. The DH60-7, R60-7, and SY75 models, which are 6-ton small excavators, are widely used in scenarios such as earthwork excavation, landscaping, housing construction, and crushing operations.

The valve body is made of high-hardness alloy steel and is formed through a single-piece machining process. The valve core and valve sleeve are precisely honed and matched, and are combined with a precise sealing interface. This design enables it to withstand the continuous erosion of high-pressure oil flow, resist wear caused by tiny impurities in the hydraulic oil, and significantly reduce common problems such as valve core sticking and increased internal leakage.

The entire valve assembly is equipped with imported quality oil-resistant and aging-resistant sealing gaskets. Regardless of the high oil temperature caused by long-term summer operation or the cold start of the machine in low-temperature environments, the sealing gasket can maintain a stable sealing effect, reducing system leakage due to sealing failure and improving common maintenance pain points such as weak engine warming, slow operation, and inability to maintain pressure. The product features a standard threaded plug-in structure. The thread specification, valve body outer diameter, oil port position, and installation dimensions are strictly in accordance with the original vehicle standards. It can be directly installed into the valve hole of the distribution valve to complete the replacement, without any modification to the pipeline or valve body. The maintenance and disassembly process is simple and convenient, significantly reducing the downtime for excavator maintenance, and is highly suitable for rapid emergency repair and replacement at the maintenance site.
