A heavy-duty, rugged pinch mechanism positions the sleeve, resulting in accurate flow control. Our 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. TECGGEAR Valve Control Products are available with pneumatic, electropneumatic, or digital positioners to link up to all control systems.SpecificationSize Range: 1" (25mm) to 36" (900mm)Temperature: -50degF to 250degFMax.

This is specially important for valves in low-pressure service(less than 2 psi) and essential in vacuum applications.The positive opening tags are attached to the exterior of the sleeve and are secured by a nylon-reinforced "Belly Band" around the outside of sleeve body. This achieves two major operational advantages. First, the pinch bar pull on the tags does not stress the internal structure of the sleeves, and no interior damange can result and long lift span is maintained.Secondly, as the "belly band" is pulled from the top and bottom, the sides are drawn toward the centerline of the valve. This mechanically assists the sleeve externally, in addition to the line pressure inside the sleeve, to return the sides of the sleeve to a completely round position. Thus structural stress on the sleeve is minimized and superior performance is enhanced.
