Product Description:

High-Performance 4-Spool Hydraulic Valve for Demanding Applications

The SD5 Manual 4-Spool hydraulic valve is a robust, high-capacity directional control valve designed to deliver superior control in hydraulic systems requiring four independent spools. Whether you’re operating agricultural machinery, construction equipment, or industrial hydraulic systems, this valve provides the reliability and precision your operation demands.

With its durable cast iron body, smooth manual operation, and compact monoblock design, it’s the ideal solution for managing multiple hydraulic actuators efficiently and safely.

Precision Flow and Pressure Management

The SD5 Manual 4-Spool valve is built for high-flow environments, supporting up to 70 L/min (16 GPM). Its maximum working pressure of 31.5 MPa (315 Bar) ensures it can handle heavy-duty hydraulic tasks with ease. This high-pressure tolerance makes it a great choice for applications where consistent hydraulic force is essential.

In addition, the valve’s parallel oil circuit design allows each spool to operate independently. As a result, users can control multiple cylinders or motors simultaneously, without performance loss.

Compact Design, Maximum Control

Although this valve handles high flow and pressure, it remains compact and easy to install. Measuring just 24×21×12 cm, the SD5 Manual 4-Spool valve fits seamlessly into most hydraulic systems. Its monoblock construction minimizes the risk of leakage and simplifies installation, while its manual lever system provides operators with responsive and accurate control.

Additionally, the valve’s four-way configuration supports versatile operations, making it suitable for multi-directional fluid flow in complex systems.

Applications Across Industries

This valve’s flexible design and reliable performance make it suitable for a variety of industries, including:

• Agricultural Equipment (tractors, sprayers, plows)
• Construction Machinery (loaders, cranes, mini-excavators)
• Industrial Systems (presses, conveyors, lift tables)
• Forestry and Material Handling Equipment

Since it features a 3/8″ BSP pressure port and standard A/B work ports (G3/8 & G1/2), integration into new or existing hydraulic setups is straightforward. Moreover, its robust build ensures consistent performance in both indoor and outdoor environments.

Built for Longevity and Low Maintenance

To keep your system running smoothly, the SD5 Manual 4-Spool valve is designed with ≤10 μm filtration accuracy. This ensures only clean hydraulic oil reaches internal components, reducing wear and extending the valve’s lifespan.

Furthermore, its compatibility with a wide viscosity range (10–400 mm²/s) and extreme temperature conditions (-40°C to +80°C) makes it dependable year-round, even in harsh environments.

Thanks to its manual operation, the valve eliminates the complexity and failure risk associated with solenoid or electronic controls—making it a perfect fit for rugged field operations.

Conclusion

The SD5 Manual 4-Spool 45 LPM Valve 3/8″ BSP Monoblock Directional Control is a powerful, efficient, and user-friendly solution for managing complex hydraulic systems. It delivers reliable high-pressure performance, smooth manual operation, and multi-spool functionality in a compact and rugged package.

Whether you’re replacing outdated components or designing a new hydraulic system from scratch, this valve offers unmatched performance, reliability, and value.
