Electric Pinch Valve (Motorized Slurry Control)

The Electric Pinch Valve, also known as a Motorized Squeeze Valve, is an automatic flow control device designed for extreme environments where media is highly abrasive, corrosive, or contains high concentrations of solids. Its core advantage is the complete isolation of the operating mechanism from the fluid, ensuring excellent resistance to acid attack and eliminating external/internal leakage.

It replaces traditional valves like stainless steel ball or plug valves in services involving slurries and corrosive waste.

⭐ Key Product Features & Advantages

Zero Leakage Guarantee: The valve achieves shut-off by squeezing a flexible rubber sleeve (tube). The sealing point is internal to the sleeve, eliminating internal and external leakage.
Extreme Media Resistance: The internal rubber sleeve is the only part that contacts the medium, making the valve highly resistant to abrasion from slurries and powders and acid corrosion.
Automated Operation: The valve is equipped with an Electric Actuator for automated, remote, or controlled operation. Other drive modes like manual or pneumatic are also available upon request.
Easy Cleaning: The full-bore, straight-through design aids in cleaning processes and minimizes pressure drop when fully open.

💡 Working Principle

The motorized mechanism converts the actuator’s rotational power into linear motion to compress the sleeve:

Closing Action: The electric device turns the stem, which simultaneously drives the upper and lower gates to move towards each other.
Sealing: The gates squeeze the internal rubber sleeve completely shut, stopping the flow.
Operation Note: Because the rubber sleeve resists compression, operators (or the actuator’s limit switches) must ensure the compression stops immediately upon full shut-off. Excessive force or manual assistance is strictly forbidden to prevent damaging the sleeve or mechanism.
