Red Valve's Series 5400 Control Pinch Valves feature centerline valve closure, true feedback positioning, compact size, enclosed mechanical parts and accurate, repeatable variable venturi flow control.
Centerline closure is extremely important for larger size pinch valves on extremely abrasive and high velocity applications. Centerline closure outlasts all other types of gate, plug or ball valves on control of abrasive and corrosive slurries. The resilient elastomer sleeve outlasts even Stellite-coated control valves.
Variable Orifice and Cone Sleeves can be specified to further enhance control performance and match the exact Cv level desired. True feedback positioning is accomplished through the direct linkage of the pneumatic positioner to the valve stem shaft. The benefits or true feedback positioning on the Series 5400 include accurate small responsive signal changes to the positioner, causing similar changes in true valve position, greatly enhancing control accuracy and repeatability.
