Red Valve Control Pinch Valves offer maximum durability with precise control and virtually no maintenance. A heavy-duty, rugged pinch mechanism positions the sleeve, resulting in accurate flow control. Red Valve Control Pinch Valves have no packing to maintain or seats to wear, no fugitive emissions and no need for expensive body alloys.
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, with no splitting of the positioner output. Red Valve Control Products are available with pneumatic, electropneumatic, or digital positioners to link up to all control systems.
To ensure that the right valve and sleeve trim is supplied for each installation, Red Valve designed a comprehensive Control Pinch Valve Sizing Program. This unique program takes into account all parameters involved in the sizing of a control valve, including pressure drop, flow rate, viscosity and much more. The program will calculate the optimum valve size and sleeve trim, and even provides more than one possible option to give the user maximum design flexibility.
