About Pinch Valve
Our manual slurry pinch valve is a control valve which uses a pinching effect to obstruct fluid flow.
About the positive opening tag
The positive opening tag are used to ensure, mechanically, that TEKO pinch valve sleeves return to a full round configuration. 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 pulls on the tags does not stress the internal structure of the sleeves, and no interior damage 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.
