Master complex multi-actuator systems with the THM SD8 Series Sectional Directional Control Valve. Engineered for heavy-duty performance and ultimate scalability, the SD8 series can be configured with anywhere from 1 to 14 sections, making it the most adaptable control hub in its class. Whether you are running an open-center or closed-center hydraulic system, this valve delivers high-pressure endurance up to 315 bar and a robust flow capacity of 90 L/min. With its modular "sectional" architecture, the SD8 allows for specialized circuit combinations, ensuring that every function of your heavy machinery operates with pinpoint accuracy and dedicated safety.

Core Technical Specifications:-

• Valve Architecture: Modular Sectional Design (1 to 14 Sections)
• Maximum Operating Pressure: 315 bar
• Maximum Flow Rate: 90 L/min
• Spool Diameter: 18 mm (Interchangeable)
• Circuit Types: Parallel, Tandem, or Series Circuits

Key Features & Engineering Advantages

• Massive Scalability: The modular design allows you to build a valve bank tailored exactly to your machine's needs—from a single-spool setup to a massive 14-section manifold for complex, multi-functional equipment.
• Individual Section Protection: In addition to the main pressure relief valve, every working section is fitted with an individual load check valve. This prevents fluid from back-flowing when a spool is shifted, ensuring that loads do not "drop" even slightly during multi-function operations.
• Interchangeable 18 mm Spools: High-precision 18 mm spools are fully interchangeable, allowing for easy maintenance and the ability to customize individual sections for different functions (e.g., double-acting, single-acting, or motor spools).
• Flexible Circuit Configurations: Supports Parallel, Tandem, or Series circuits, giving designers the ability to prioritize speed, torque, or simultaneous operation across different actuators.
• "Power Beyond" Capability: Available with an optional carry-over port, allowing the SD8 to act as a high-pressure source for additional downstream valves, simplifying complex hydraulic plumbing.
• Specialized Intermediate Sections: Available with intermediate sections and a wide range of port valves to meet the unique requirements of specialized industrial or mobile circuits.
• Rugged Manual Control: Built for tactile reliability, the SD8 is optimized for manual control, providing operators with direct, "mechanical-feel" feedback in the most demanding environments.

Ideal Industry Applications:-

The scalability and high-pressure rating of the SD8 Series make it the premier choice for:

• Heavy Civil & Road Machinery: Managing multiple complex functions on asphalt pavers, motor graders, and medium-sized excavators.
• Agricultural Equipment: Ideal for multi-function harvesters, forestry equipment, and complex tractor-mounted implements.
• Waste & Sanitation Vehicles: Controlling the various lifting, tipping, and packing cycles on multi-function refuse trucks.
• Material Handling & Cranes: Providing secure load-holding and precise directional control for mobile cranes and large-scale lifting platforms.
