Additional Info
Original manufacturer: Northman, commonly known as Haitian dedicated hydraulic valve. High precision ground spool, low internal leakage and excellent durability.
I. Product Features
1. Oil-immersed Electromagnetic Operation Design: The spool operates immersed in the oil within the system, providing lubrication. This ensures smooth and silent operation even under high pressure and high-frequency switching conditions.
2. High Energy Efficiency: The valve body's flow channel is specially designed with low internal impedance, reducing internal pressure loss and improving energy efficiency, thereby lowering operating costs.
3. Reduced Temperature Rise and Extended Service Life: Due to the low internal impedance and reduced pressure, the temperature of the hydraulic oil is correspondingly lowered, preventing oil degradation and extending its service life. This reduces the frequency of oil changes and associated costs. Additionally, the machine itself is less affected by heat, preventing accuracy errors or deformation due to thermal expansion, thus saving on maintenance expenses.
4. High-Pressure Application: This electromagnetic directional control valve can be used under high pressure, with a maximum pressure rating of up to 315 bar (specific pressure range may vary depending on the model and configuration), making it suitable for high-pressure and large-flow applications.
5. Special Coil Design: The electromagnetic coil is made of special materials and features a unique anti-loosening design for the fixing nut, preventing coil detachment due to vibration and ensuring operational safety.
6. Excellent Electrical Installation Waterproof and Dustproof Properties: The electrical connection methods include junction boxes and plug-in connection sockets, both equipped with indicator lights. The electrical junction box has a tightly sealed waterproof and dustproof design.
7. Easy Installation: The valve body's fixing bolts are externally connected, facilitating easy disassembly and assembly. Additionally, the ample space for electrical wiring makes installation and connection straightforward.
