Conical Shape Double-Wall Sleeve Bubble Tight Close Body Control Pinch Valve For Modulating
The Original Pinch Valve is simple and ingenious. Developed to handle corrosive and abrasive water in flooded coal mines or other aggressive liquid, The valves could restrict flow by using a pinching mechanism to bear down on a rubber sleeve. That simple idea now serves as the basis for more sophisticated products. We carry a full line of pinch valves for on/off or modulating service that are non-clogging and resistant to abrasive, corrosive, and scaling fluids. They are ideally suited for difficult slurries and other demanding applications.
Many styles have common lengths with Plug, Gate, and Ball Valves for interchangeability. The product can close drop-tight on solids and is available with customized actuators, controls, and port sizes. The sleeve is the only part exposed to the process fluid and can eliminate the need for expensive body alloys.
The flow pattern of TEKO-Valve's pinch valves are inherently streamlined making them well suited for modulating service, however sizing then becomes critically important. For an on / off valve, port sizing is a simple case of maximum flow. If it is determined that a smaller valve can be used, the benefit is primarily economic. For a modulating valve, our Control Pinch Valve, port sizing is critically important for performance reasons and both maximum and minimum flows must be considered.
Sleeve Production
Pinch valves are commonly applied in aggressive, abrasive and corrosive media types or in high-pressure applications. To stand these conditions TEKO sleeves are handmade layer by layer in a quality process covered by Standard.
High grade sleeve materials range from wear resistant styrene butadiene to numerous other elastomers and rubber compounds. They are highly resistant to abrasive / corrosive slurries, powders and granular substances.
Sleeve Special Design
Several sleeve design options such as a conical sleeve for control valves and a suction sleeve for negative pressure applications are available.
| Design | Applications |
| Suction sleeve | Specially designed for negative pressure applications e.g. suction lines and for applications where sleeve pulsation occurs |
| Suction sleeve
| Sleeve with polyurethane lining ensure improved protection against wear |
| Sensomate sleeve | Detects and signals critical wear |
| Conical sleeve
| Ensure the most accurate control in flow control applications |
