This product is a professional hydraulic control valve component with stable performance and reliable quality. It is widely matched with various construction machinery, industrial hydraulic equipment and special vehicle hydraulic systems. It is mainly used to control hydraulic oil circuit switch, pressure balance and flow control, and can adapt to various complex working environments to ensure smooth and safe operation of the whole hydraulic system.

It is suitable for standard industrial mineral hydraulic oil, and the fluid cleanliness shall meet the common hydraulic system usage standard. The product can work stably under rated working pressure and withstand short-term impact pressure within the safe range. It can maintain stable working performance in normal working ambient temperature range. The internal sealing structure is excellent with low internal leakage. The overall operation is smooth, the action is sensitive, and it has long continuous working service life.

Adopt high-precision machining technology for internal core parts, with good wear resistance and compression resistance. The overall structure is compact and reasonable, easy for on-site installation and layout. The internal oil passage is optimized to reduce flow resistance and improve hydraulic transmission efficiency. It has good vibration resistance and impact resistance, and will not be easily affected by equipment vibration during operation. Simple internal structure, fewer failure points and convenient later inspection and maintenance. Standard installation size, strong versatility and easy replacement and matching.

Clean the installation surface and internal oil passages thoroughly before installation to remove all impurities and oil stains. Align the product with the installation position accurately and fix it with standard fasteners according to the specified fastening strength. Do not use excessive force to avoid component deformation and internal clamping stagnation. Connect hydraulic pipelines strictly according to the oil inlet and outlet direction, and ensure all joints are connected tightly without loose gaps. After installation, check the overall assembly state again to confirm no installation deviation.

Complete all installation work and pipeline connection, then carry out no-load test operation. Slowly fill hydraulic oil into the system and check all connection positions for oil leakage. After confirming no abnormal conditions, start formal equipment operation. Keep the circulating hydraulic oil clean in daily use, and avoid impurities entering the valve body to cause blockage and failure. It is forbidden to use the product beyond the rated pressure and working limit. When stopping the equipment, stop the working action first, then release the system internal pressure steadily.

Regularly check the appearance and connection parts of the product, and deal with oil seepage and looseness in time. Replace hydraulic oil and system filter elements regularly according to the working cycle to ensure clean oil quality. Regularly observe the working action state of the valve, and adjust and maintain in time if slow action and unsmooth switching occur. Keep the product surface clean to prevent dust and oil dirt from accumulating and affecting heat dissipation and normal use. It is not allowed to disassemble the product privately without professional technical support, so as not to damage the internal precision matching structure.

All installation, disassembly, maintenance and debugging operations must be completed after the equipment is shut down, power is cut off and all hydraulic pressure is completely released, so as to prevent high-pressure hydraulic oil from causing personal injury. Operators shall abide by relevant safe operating norms. Keep the product away from high temperature heat sources, open fire and corrosive substances to prevent accelerated aging and performance failure. Once abnormal noise, excessive heating and functional failure occur during operation, stop using immediately and arrange professional personnel for inspection and troubleshooting.
