Dual Pinch Valve Open Body Type (DPVO)

Dual’s Pinch Valve consists of a tough, but flexible bore sleeve, which forms part of the pipeline. The valve is closed mechanically via movement of the Pinch Bars located on the opposite sides of the sleeve. The core of the Dual Pinch Value is the sleeve – this sleeve is reinforced with high-strength fabric. The valve are well suited for on/off and throttling control applications where scale build up is a problem.
