Product Description:

Heavy-Duty 3-Section Hydraulic Valve for Precision Control

The SD5 3-Section Hydraulic Valve is a high-performance directional control valve designed to manage hydraulic flow in complex systems with accuracy and reliability. Built for demanding environments, this valve supports double-acting operations and is perfectly suited for machinery requiring smooth, responsive, and efficient hydraulic actuation across three sections.

Whether you’re working in agriculture, construction, forestry, or industrial hydraulics, this valve ensures precise control and long-lasting performance—even under high-pressure conditions.

Engineered for High Flow and High Pressure

The SD5 3-Section Hydraulic Valve handles a maximum flow rate of 70 L/min (16 GPM) and operates safely at pressures up to 31.5 MPa (315 Bar). This makes it ideal for applications where consistent hydraulic force and fluid direction control are critical.

Additionally, it supports parallel oil circuits, which allows all sections to function independently without losing performance. This means multiple actuators can be operated simultaneously—improving workflow, efficiency, and system response time.

Compact, Rugged, and Efficient

Despite its 3-section functionality, this valve is impressively compact. Measuring only 18.5 × 19 × 10 cm, it fits easily into tight spaces while delivering maximum hydraulic performance. Additionally, its robust cast iron and tube-structured body ensures long-lasting durability—even under intense operating cycles and extreme temperatures.

Not only does its compact size make installation easier, but the valve’s modular design simplifies maintenance. Each spool section can be serviced or replaced independently, reducing downtime and maintenance costs.

Ideal for a Wide Range of Applications

Thanks to its double-acting functionality and parallel oil circuit, the SD5 3-Section Hydraulic Valve is suitable for:

• Tractors and agricultural implements
• Skid steers and loaders
• Construction machinery
• Forestry equipment
• Hydraulic presses and lift systems

Because it supports three-way operation, operators can precisely control multiple hydraulic cylinders or motors—streamlining machine efficiency and enhancing productivity.

Safe, Clean, and Easy to Maintain

To protect your hydraulic system, this valve features ≤10 µm filtration accuracy. This high filtration level prevents contaminants from damaging sensitive components, thereby improving operational reliability and extending system life.

In addition, its spring-centered spool return provides automatic re-centering, which helps avoid control errors and enhances safety—especially in mobile applications where control precision is critical.

The valve is also engineered to handle a wide viscosity range of 10–400 mm²/s, allowing it to operate with various grades of hydraulic oil and in diverse temperature environments.
