Product Overview
Essential Control for Heavy Machinery.
The Hydraulic Solenoid Valve Core is the critical mechanical heart of the hydraulic control system. Designed specifically for heavy-duty applications such as Excavators, this component bridges the gap between electrical signals and hydraulic force. When the solenoid is energized, this core actuates with high precision to direct fluid flow, ensuring smooth and responsive machinery operation.

Produced by Shenzhen Sunmy Hardware Co., Ltd., this part represents the intersection of electrical actuation and mechanical precision, engineered to withstand the rigorous pressure and temperature demands of the construction industry.

Process & Manufacturing Insights
Expertise in Precision Turned Parts.
At Sunmy, we utilize state-of-the-art manufacturing technologies to produce valve cores that meet strict OEM standards.

Precision CNC Turning
The main body is crafted using advanced CNC lathes. This allows us to achieve tight geometric tolerances (concentricity and varying diameters) essential for a jam-free sliding motion within the valve body.

Material Integration
The component features a seamless integration of a durable metal shaft (Steel/Stainless Steel) with a high-grade engineering plastic knob (identified as PA66 GF30 – Polyamide with 30% Glass Fiber reinforcement) for superior thermal and mechanical resistance.

Surface Finishing
The metal stem undergoes precision grinding and polishing to reduce friction and wear, ensuring a long lifecycle even under high-frequency cycling.

Assembly & Sealing
Pre-installed with high-quality O-rings (Green/Black FKM or NBR) to ensure zero leakage under high hydraulic pressure.
