Key Features Premium Materials: It is made of premium vermicular graphite cast iron with the CNC machining and galvanizing processes, which is sturdy, not easy to deform, wear-resistant, impact-resistant. Extreme Pressure Resilience: Engineered to withstand intense hydraulic mechanisms with a Max operational pressure of 31.5MPa, this feature ensures optimal performance and reliability even under the most demanding machine operations. Powerful Function: Using a parallel oil circuit, 7 spools with joystick control, this 7-spool valve is used to operate the double-action cylinder and accurately controls various parts of the hydraulic machinery, which is more convenient and practical to use. Advanced Flow Management: Featuring a maximum flow capacity of 13 gallons per minute and an adjustable pressure relief valve, this mechanism delivers precise and efficient fluid control to satisfy a wide range of operational demands. Thoughtful Design: The oil drain port bolt is protected by a protective cover to prevent wear and extend its service life. This product is designed with sealed grooves, which can effectively prevent leakage and also serve to separate the oil chamber. The valve core return spring is made of galvanized alloy material, which has better corrosion resistance. High Security: Incorporating an internal check valve to prevent hydraulic oil backflow and an adjustable relief valve to fine-tune mechanism pressure, this feature significantly improves operational stability and overall safety. Application This product is widely used in warehouses, factories, construction sites, and other locations, and is suitable for small tractors, tractor loaders, wood splitters, forklifts, sanitation vehicles, and other mobile equipment.
