The 4WE10 high-pressure solenoid directional valve is a mature control component for medium and high-pressure hydraulic systems. Its core advantages are concentrated in multiple dimensions such as high-pressure and high-flow adaptability, operational reliability, and ease of maintenance. The specific advantages are as follows:
1. Strong adaptability to high pressure and high flow
Excellent pressure-bearing performance: The maximum working pressure of the A, B, and P interfaces can reach 315bar, and the nominal pressure of some upgraded models can reach 350bar. It is suitable for most medium, high, and heavy-duty hydraulic systems.
Adequate flow capacity: Supports a maximum flow of 120~160L/min. By optimizing the valve port flow channel structure, the resistance is reduced, the system pressure drop is reduced, and the demand for rapid reversal of medium and large flow conditions is met.
2. Stable operation and long life
Wet coil design: The electromagnetic coil can be directly immersed in the hydraulic oil, greatly improving the heat dissipation efficiency and controlling the temperature rise within 45K. Compared with the dry coil, it has lower noise and longer continuous working life. The average number of fault-free switching can reach more than 12 million times.
High sealing reliability: Optional fluororubber sealing material, with a temperature resistance range of -30℃~90℃, can withstand a variety of hydraulic media, extremely low internal leakage under high pressure, and the leakage can be controlled within 0.1mL/min under a pressure difference of 100bar.
Excellent valve core accuracy: The valve core centering accuracy can reach ±0.008mm. The valve body is made of ductile iron and has been precision honed on both sides. It has strong anti-pollution ability and is not prone to jamming and crawling problems during long-term operation.
3. Easy installation and maintenance
Flexible coil design: The electromagnetic coil can be rotated 90° to adapt to different spatial layouts. There is no need to open the pressure sealing chamber of the valve when replacing the coil, improving maintenance efficiency by 50%.
Manual emergency operation: Equipped with a concealed manual emergency push rod as standard, the valve core position can be manually switched during power outage or failure, which facilitates equipment debugging and troubleshooting and avoids complete loss of control of the system.
Good installation compatibility: Complies with ISO 4401 international standard installation dimensions, supports plate installation, facilitates hydraulic system integration, and can directly replace mainstream brand products of the same specifications.
4. Wide scene adaptability
Strong electrical compatibility: Supports a variety of power supply specifications such as 24VDC and 220VAC, allowing voltage fluctuations of ±10%, with a protection level of IP65, and can be adapted to harsh outdoor, humid, and dusty industrial environments.
Rich function options: Provides a variety of intermediate functions such as J, E, H, O, etc., which can be adapted to different circuit needs such as unloading, pressure maintaining, and hydraulic cylinder floating, covering most hydraulic application scenarios such as machine tools, engineering machinery, metallurgy, and plastic machinery.
Strong scalability: Optional valve core position feedback contacts and LED status indicators can be directly connected to the PLC interlocking logic of the automated production line to reduce the density of system fault points.
