Truflo Pinch Valves

Truflo Pinch Valve

High-pressure control across diverse industries and applications.

The Truflo Pinch valve is specifically designed to replace diaphragm valves and has the same face to face dimension. It outperforms and outlasts diaphragm valves and is environmentally more efficient than diaphragm valves. The 100% full port design eliminates any dead spots or crevices and the valve is an extension to the pipe in the fully open position, with no turbulence and no head loss.

The self- cleaning flexing action of the sleeve eliminates inline scaling and blockages. All mechanical parts are completely isolated from the medium. The valve has only five major components, making it easy to use, easy to maintain and it is extremely fitter friendly. The valve, like all Atval pinch valves, is bi-directional and offers drop tight shut off across the full pressure range.

Full pressure rating is maintained throughout the size range, i.e. it does not decrease in the larger valve sizes however, mechanical assistance may be necessary for sizes 200mm and above. Please consult the factory as this is factory related.
