HD – SED6 – 3/2 and 4/2 Way Directional Poppet Valves with Solenoid Actuation
Achieve absolute, leak-free directional control in your mid-pressure hydraulic systems with the HD SED10 Series. Available through Thm Hydraulics, these direct-operated poppet valves with solenoid actuation provide dependable and efficient fluid regulation in a robust Size 10 frame. Engineered with a specialized poppet-and-seat architecture, the SED10 ensures a 100% tight seal in the closed position, preventing internal bypass leakage. Capable of handling operating pressures up to 350 bar and flow rates up to 40 L/min, this valve series is the ultimate choice for applications where pressure retention, safety, and precise holding are critical.
Core Technical Specifications:-
- Component Architecture: Direct Operated Directional Poppet Valve
- Nominal Size: Size 10 (NG10)
- Ways/Positions: 3/2 Way or 4/2 Way (Configuration dependent)
- Maximum Operating Pressure: Up to 350 bar
- Maximum Flow Capacity: Up to 40 L/min
- Actuation Type: Solenoid Actuated (Direct)
Key Features & Engineering Advantages:-
- Absolute Leak-Free Seating: Unlike traditional spool valves, the poppet design features zero internal leakage at the closed ports. This is essential for load-holding applications, preventing unintended cylinder drift and ensuring exact positioning.
- Dependable Solenoid Operation: The direct-acting solenoids ensure smooth, responsive, and reliable switching. The valve is designed to operate flawlessly even after remaining under pressure in one position for long periods, eliminating "stiction."
- Integrated Safety: Comes standard with a protected manual override, allowing technicians to manually trigger the valve for system testing, commissioning, or emergency operation during a power failure.
- Robust 350 Bar Performance: Built to withstand standard high-pressure industrial environments, ensuring consistent torque and power output for your actuators.
- Flexible Standardized Mounting: Adheres to DIN 24340 Form A, ISO 4401, and CETOP standards (optional pattern compatibility), ensuring seamless "drop-in" installation on global manifold designs.
- Individual Electrical Connection: Designed with an individual electrical connection for straightforward, error-free wiring in your control cabinet.
Ideal Industry Applications:-
The leak-free poppet design and 350 bar pressure rating make the HD SED10 the premier choice for:
- Work Holding & Clamping: Maintaining precise pressure in hydraulic clamps and fixtures for CNC machining centers.
- Load-Holding Circuits: Serving as the fail-safe blocking valve in lifting platforms, presses, and safety machinery to prevent accidental movement.
- Injection Molding Machinery: Managing auxiliary functions in molding equipment where cleanliness and accuracy are vital.
- Accumulator Charging Systems: Controlling the flow from hydraulic accumulators, ensuring no pressure loss during standby periods.
Why Choose the HD SED10 Series?
- Zero Energy Loss: By stopping internal leakage, your pumps run more efficiently and your system maintains its set pressure without constant correction, lowering operational costs.
- Uncompromising Safety: For load-holding applications, the SED10 provides the ultimate peace of mind. As long as the valve is closed, the load stays where you put it.
- Direct-Acting Simplicity: By eliminating pilot lines, the SED10 removes potential failure points, offering a compact, reliable, and straightforward solution.
