Bubble Tight High Performance Low Pressure Air Operated Slurry Pinch Valve
TEKO Air Actuated Pinch Valves offer a cost-effective solution to flow control problems. Adding air pressure within the annular space between the body and the sleeve can open, throttle or close the valve.
TEKO Air Actuated Pinch Valves offer a cost-effective solution to flow control problems. The key is in the rubber sleeve - the valve's only wetted part. Actuation of the valve is accomplished by air or hydraulic pressure placed directly on the elastomer sleeve. Adding air pressure within the annular space between the body and the sleeve can open, throttle or close the valve. The valve body acts as a built-in actuator, eliminating costly hydraulic, pneumatic, or electric actuator. The sleeve’s elasticity allows the valve to close drop-tight around entrapped solids, eliminating hang-ups that can damage the valve. Sealing area is equal to 95% of the valve’s length. In general, 25 psi over line pressure is required for full closure of air actuated pinch valves.
there are no seats or packing to replace, or cavities or dead spots to collect debris and bind valve operation. Special design sleeves made of imported rubber provides good performance for the valve. . When the valve is open, it is like a straight piece of pipe in the line. The Valves are used on remote locations or harsh environments since there are no external links, levers, pistons or rotating parts to cause downtime.
Throttling control is accomplished by using a booster or proportional relay to modulate air pressure to this type valve. A changing air signal through the proportional relay will modulate the Valve.
How does air operated pinch valve work?
Supplying compressed air/fluid (minimum pressure difference 2 bar) into the casing of the TEKO air operated Pinch Valve compresses the sleeve, which is specially manufactured with high rebound elasticity. The body's design guarantees that the sleeve can close freely to form a lip shape. This ensures that the product flow is completely sealed off tight and that the sleeve is guaranteed the longest service life at the same time. This closes the air operated Pinch Valve and completely seals off the flow of the product.
The maximum operating pressure is dependent on the nominal diameter and is around 2-6 bar. As soon as the supply of compressed air/fluid is interrupted, and the air operated Pinch Valve casing is vented or drained, the specially manufactured sleeve is opened by its rebound elasticity/resilience, enabling the pressure in the medium to flow through the full passage of the TEKO air operated Pinch Valves.
What are the benefits of air operated pinch valves?
Free flow of product, minimum frictional resistance, 100% leak free, no blockages and low net weight are among the most important benefits of air operated Pinch Valves.
A flattened and elliptical casing design of all flanged types ensures minimum compressed air consumption. This results in energy savings and ensures a specified, lipped fold pattern to the sleeve of the air operated Pinch Valve. This specific, lipped fold pattern ensures the complete sealing of the product flow. Even large solids are enclosed by the sleeve in the air operated Pinch Valves and are thus tightly sealed.
