HS4 Series Hydraulic Sectional Directional Control Sliding Spool Valve

HS4 Series Hydraulic Sectional Directional Control Sliding Spool Valve

In modular hydraulic systems of small-scale construction machinery, agricultural equipment and light industrial production lines, the flexible control of the flow direction of hydraulic oil is of vital importance. The HS4 series hydraulic plate-type directional control slide valve is precisely the key component designed for this demand, which can precisely direct the hydraulic oil to the actuator according to the operational requirements. This slide valve features a precisely machined valve core that slides within the valve body, achieving smooth switching of the hydraulic flow direction by opening or closing the oil circuit. The HS4 hydraulic valve adopts a plate-type structure design and supports modular combination. It can be flexibly adapted to multi-directional control systems and is particularly suitable for equipment with limited installation space.

The HS4 hydraulic valve performs exceptionally well in modular systems thanks to its precise directional control and flexible assembly capabilities.

• Precision spool valve control: The valve core is ground to the micron level and fits closely with the valve body, keeping the internal leakage within 0.1L /min, effectively maintaining the system pressure and avoiding energy loss
• Fast dynamic response: The movement resistance of the slide valve is less than 5N, and the direction switching time is less than 100ms (such as in the precise lifting and lowering of agricultural machinery booms and other operation scenarios)
• Advantages of modular assembly: Compared with integral valves, this spool valve supports the combination of 2-4 valve groups according to actual needs (for example, simultaneously controlling the lifting cylinder and the tilting cylinder), reducing redundant components
• Maintenance convenience: When a single plate valve malfunctions, it can be replaced independently without disassembling the entire valve, minimizing downtime to the greatest extent

HS4 series split-type multiway valve has introduced European advanced technology, including compact structure, high pressure resistance, long service life, 1-14 connections, and two hydraulic systems of middle opening and middle closing. HS4 each piece of valve body can be according to customer requirements to increase the overflow valve, filling oil valve. The control methods include manual control, pneumatic control, electro-hydraulic control and flexible shaft remote control. The valve is widely used in construction machinery, sanitation machinery, mining machinery and other machinery hydraulic system.
