Key Features & Engineering Advantages:-

• Accurate Load Handling: The advanced flow regulation mechanism ensures a uniform hydraulic flow. This guarantees perfectly smooth, stable lifting and lowering, preventing sudden drops or jerks that could damage delicate cargo or endanger operators.
• Integrated Pressure Protection: A built-in pressure relief function actively protects the entire hydraulic circuit from dangerous overloading and violent pressure spikes, drastically extending equipment life and reducing maintenance downtime.
• Fail-Safe Emergency Operation: In the event of a sudden electrical power failure or pump malfunction, the valve features an optional emergency manual needle valve or push-button. This allows operators to safely release the pressure and manually lower the load to the ground.
• Shock-Absorption Capability: Specifically engineered internal geometries prevent destructive hydraulic shock during actuation, safeguarding your rigid piping and cylinder seals.
• Compact & Corrosion-Resistant: The high-strength aluminum block construction delivers a massive power-to-weight ratio while remaining highly resistant to the harsh, corrosive environments of outdoor job sites and industrial warehouses.

Working Principle & Operation:-

• Lift Up: When the electric motor is activated, pressurized fluid extends the cylinder. A built-in hydraulic check valve automatically locks the system pressure, safely holding the load in the elevated position without requiring continuous pump operation.
• Lower Down: To descend, the pump motor remains off. The solenoid valve is energized, smoothly releasing fluid back to the tank. The integrated flow control valve meticulously governs the descent speed, ensuring it remains controlled and uniform regardless of the load's weight.

Series Variants & Ideal Applications:-

• ET-02 (Light Duty): The ideal compact solution for smaller hydraulic systems requiring precise flow regulation. Perfect for pallet stackers, light goods lifts, agricultural machinery, and compact scissor platforms.
• ET-04 (Heavy Duty): Engineered to process higher flow rates and massive loads. It delivers the increased durability and capacity required for heavy industrial lifts, hydraulic tail lifts on commercial trucks, and heavy construction equipment like cranes and boom lifts.

Why Choose the THM ET-02/04 Series?

• Uncompromising Safety: Built-in relief valves and emergency manual overrides ensure your payload and personnel are always protected, even during power failures.
• Load-Independent Descent: The advanced flow control mechanism guarantees a uniform, safe lowering speed, regardless of how heavy the cargo is.
• Rugged Simplicity: The machined aluminum block and highly durable internal cartridges require minimal maintenance, significantly lowering your total cost of ownership.
