Dual Pinch Valve Open Body Type (DPVO)
Dual Pinch Valve Open Body Type (DPVO)
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 above and below the sleeve. The core of Dual Open body pinch valve is the sleeve. The valves are well suited for on/off application use as well as throttling control applications involving slurries, powders, liquids, granulated materials and where scale build up is a problem.
