The Oil Distribution Valve (Part No. 86746930) serves as a core hydraulic control accessory specially designed for Hydraulic Rock Drills — a critical component that directly determines the operational efficiency and stability of hydraulic rock drilling equipment in mining and construction scenarios. It precisely distributes hydraulic oil flow to different actuators of the rock drill and dynamically adjusts the drill’s impact frequency and propulsion speed according to actual working conditions. We manufacture this accessory in strict accordance with the original technical standards of hydraulic rock drills, so it suits various hydraulic rock drill models operating under harsh working conditions, including open-pit mining, underground tunnel excavation, quarry stone crushing, and infrastructure construction rock drilling projects. Whether facing high-intensity continuous operation requirements or complex geological environments with gravel and vibration, the valve maintains stable performance and ensures the smooth progress of drilling operations.
Compared with ordinary oil distribution valves on the market, the Oil Distribution Valve Part No. 86746930 adopts a high-wear-resistant alloy steel material formula we independently optimized for hydraulic rock drill working characteristics. Our production team applies multi-stage precision machining processes, including CNC turning, milling, and honing, to shape the valve body. We also add a professional anti-corrosion and anti-wear coating on the valve body surface, which effectively enhances its resistance to hydraulic oil erosion, mechanical vibration wear, and external environmental corrosion. In terms of performance advantages, the valve achieves ultra-high pressure resistance up to 31.5 MPa, delivers excellent sealing performance to eliminate hydraulic oil leakage risks, and offers strong impact and wear resistance to adapt to long-term high-load operation. These superior performance characteristics not only reduce the failure rate of the rock drill’s hydraulic system but also significantly extend the service life of the entire rock drill equipment, thereby cutting down the frequency of equipment maintenance and accessory replacement for users and saving their long-term operation costs.
In terms of installation and application, we design this oil distribution valve with a perfect fit to the original hydraulic rock drill interface. Users can directly connect it to the original hydraulic pipelines without additional modification, drilling, or adjustment of the hydraulic circuit. It fully matches the hydraulic circuit design of mainstream brand hydraulic rock drills and covers most models of well-known brands in the industry. The installation process is simple and efficient, requiring only basic hydraulic tool operation and professional technical guidance, which greatly shortens equipment maintenance downtime. For mining construction units, infrastructure engineering companies, and equipment maintenance service providers, this accessory acts as an indispensable high-quality replacement part that helps maintain stable equipment operation, improve construction efficiency, and ensure the on-schedule completion of project construction periods. In addition, we equip the product with a complete quality inspection certificate and installation manual, providing users with a full range of after-sales support and technical guidance.
