The Red Valve Series 5200 Control Valve design offers maximum durability with precise control and virtually eliminates maintenance. A heavy-duty pinch mechanism positions the sleeve for accurate control over a wide flow range. The valve has no packing to maintain or seats to wear, and the elastomer sleeve eliminates the need for expensive alloy bodies.

In sizes over 4", a bottom pinch bar is used to reduce the stroke length of the valve by pre-pinching the sleeve into a D-shaped port. The D-Port provides a more immediate response to control signal with no loss of flow capacity.

Cone Sleeves can be specified to further enhance control performance and match the exact C_v level desired. True feedback positioning is accomplished through the direct linkage of the pneumatic positioner to the valve stem shaft. There is no splitting of the positioner output. The benefits of true feedback positioning on Red Valve's Series 5200 valves are accurate small-change response signals to the positioner, causing similar changes in true valve position, greatly enhancing control accuracy.
