Dual Pinch Vavle Fully Enclosed Body Type (DPVFE)
Dual Pinch Valve Fully Enclosed Body Type (DPVFE)
Dual’s Pinch Valve consists of a tough, but flexible full bore sleeve, which forms part of the pipeline. The valve is closed mechanically via movement of the Pinch Bars located on opposite sides of the sleeve. The core of the Pinch Valve is the sleeve. The sleeve is reinforced with high-strength fabric. The valves are well suited for on/off and throttling control applications where scale build up is a problem. The valve body is fully enclosed, no outside moving parts.
