THM – WEMM – Directional Valve
Gain absolute control over your hydraulic systems, even in the event of a total power failure, with the THM WEMM Series. This specialized solenoid-operated directional valve combines the high-cycle automation of an electronic control valve with the rugged reliability of a physical emergency handle. Engineered for mission-critical applications where safety and manual intervention are non-negotiable, the WEMM series supports maximum working pressures up to 350 bar and flow rates up to 120 L/min. Whether you are managing heavy construction attachments or industrial safety systems, the WEMM series ensures your machinery remains operational and safe, regardless of electrical status.
Core Technical Specifications:-
- Valve Architecture: Solenoid Operated Directional Spool Valve
- Manual Integration: External Emergency Hand Lever
- Standard Sizes: Size 6 (NG6) and Size 10 (NG10)
- Maximum Working Pressure: 350 bar
- Maximum Flow Rate: Up to 120 L/min
Key Features & Engineering Advantages:-
- Integrated Emergency Manual Handle: Unlike standard solenoid valves with "hidden" overrides, the WEMM series features a robust, ergonomic handle. This allows operators to manually shift the spool with high leverage during electrical failures, maintenance, or emergency shutdowns, ensuring the machine can be safely repositioned.
- Extreme 350-Bar Resilience: The valve body is precision-cast and reinforced to handle the high-pressure surges and aggressive duty cycles typical of heavy civil and road machinery.
- Dual-Control Versatility: Offers the best of both worlds—seamless electrical automation for standard operation and immediate mechanical override for manual troubleshooting or emergency backup.
- High-Flow Efficiency: Despite the integrated manual mechanism, the internal flow paths are optimized to deliver up to 120 L/min (Size 10) with minimal pressure drop, maintaining the energy efficiency of your power unit.
- Rugged Outdoor Durability: Built to withstand the vibrations, dust, and moisture of harsh outdoor environments, making it a reliable choice for mobile equipment that cannot afford downtime.
Ideal Industry Applications;-
The manual override and high-pressure rating of the WEMM Series make it the primary choice for:
- Heavy Civil & Road Machinery: Managing safety-critical boom movements or steering overrides on asphalt pavers, road rollers, and motor graders.
- Emergency & Recovery Vehicles: Directing flow for hydraulic winches and stabilizers on tow trucks and heavy-duty recovery cranes.
- Drilling & Mining Equipment: Providing a manual failsafe for drilling feed circuits and auxiliary mobile supports.
- Industrial Safety Circuits: Serving as a primary control point for heavy-duty factory presses and material handling systems that require a manual "home" or "release" function.
