Built for Performance – OEM SD8 Manual 8-Spool Sectional Control Valve
For industries that rely on strong and accurate hydraulic control, the OEM SD8 Manual 8-Spool Sectional Control Valve is a solid and smart solution. Built for heavy industrial machinery, this valve is designed to manage multiple hydraulic functions smoothly and safely. With support for up to 8 spools, it offers great control while handling high flow rates and pressure with ease.
Whether you’re working with construction equipment, factory machines, or agricultural systems, this valve brings power, safety, and simple control together in one compact unit.
Key Features of the OEM SD8 Manual 8-Spool Sectional Control Valve
The OEM SD8 Manual 8-Spool Sectional Control Valve stands out with its strong design, high flow performance, and flexibility in control options. Let’s take a closer look at what makes this valve a top choice in demanding environments.
High Flow and Pressure Performance
Built to manage heavy-duty tasks, this valve supports a maximum flow rate of 80 L/min (or 16 gallons per minute) and operates at pressures up to 350 bar (35 MPa). This makes it suitable for tough applications that require consistent hydraulic pressure and flow.
Sectional Design for Full Control
Thanks to its modular 8-spool configuration, this valve lets you control multiple hydraulic functions from one location. The design supports 1 to 14 sections, so it can be customized for your system’s needs. This setup is especially useful in machines where several components must be operated independently.
Compact Yet Strong
Despite its strength, the valve is compact in size — measuring 42 x 27 x 14 cm and weighing 30.5 kg. This makes installation easier and allows it to fit well into different machine layouts without taking up too much space.
Smooth Operation with Flexible Control Options
Manual and Remote Control Options
The OEM SD8 Manual 8-Spool Sectional Control Valve gives you several control choices. On the spring side, you can use either spring return or detent controls. On the lever side, you have the option of:
- Manual control
- Pneumatic control
- Electric and pneumatic control
- Hydraulic and electric control
- Hydraulic control
- Remote control
These options allow you to adjust the control system to match your machine’s design and your operator’s preference.
Wide Range of Spool Functions
The valve supports various spool function types including O, P, Y, and A, allowing you to choose the one that fits your hydraulic tasks best. Whether your system needs simple directional control or more advanced functions, this valve has you covered.
Clean, Reliable, and Efficient
Excellent Filtration and Oil Support
This valve is made to keep your hydraulic system clean and efficient. It works with hydraulic oil and supports a filtration accuracy of ≤10µm, protecting your machinery from damage caused by particles or debris. The suitable viscosity range of 10–400 mm²/s means it works well with a wide range of hydraulic oils.
Works in Harsh Conditions
With a temperature range of -40°C to +80°C, the OEM SD8 Manual 8-Spool Sectional Control Valve performs reliably in both freezing and hot environments. This makes it perfect for outdoor machines, factory floors, and field equipment.
Easy Installation and Compatibility
Port Sizes and Connections
This valve comes with standard G1/2 and G3/4 work ports, and a ¾-inch pressure port, ensuring easy connection to most hydraulic systems. The L-type screw port connection makes it simple to install or remove the valve without special tools.
