Manual Pinch Valve

Manual Pinch Valve

Pinch valves are commonly used in wastewater treatment plants (sludge treatment, gravel cleaning, raw sewage, lime, carbon sludge), power plants (FGD systems, ash removal systems, coal conveying), mining (tailings, flotation control, sludge discharge lines, tailings filling, various other slurries) chemical processes (corrosive and abrasive media, powders, particles) and paper mills, food industry, pulp mills, glass, electronics industry, cement industry, sand,  and industrial wastewater treatment plants and many other fields.

Description

Description of Manual Pinch Valve

Pinch valves are ideal valves for fluids containing solid particles or contaminants to isolate and regulate pipelines. Because the sleeve is the only part in touch with the medium, it is extremely resistant to wear and corrosion. Even if complicated chemical processes are occurring in the pipeline, the pinch valve is still easy to handle them. Its applications include power plants, sewage treatment plants, mining, and chemical process control.

Which Benefits Will You Get If Buy Pinch Valves From THINKTANK?

● High Wear and Corrosion Resistance

Our pinch valves can handle all types of medium concentration acid and arbitrary concentration alkali salt solution, and these pinch valves can carry pulp, dry and wet powder, and crystalline material medium.

● Complete Diameter

When the pinch valve is open, its overall design may be totally integrated with the pipeline system; it won’t modify the pipe’s diameter or structure and has no impact on the pipeline’s flow medium.

● Can be Closed with Particles

Because the pinch valves are self-cleaning, any particles that accumulate in the sleeve wall are broken away when the valve is activated. This is attributed to the sleeve’s flexibility, which allows the valve to last longer than many rival products currently on the market.

● There is No Leakage.

When the valve is coupled to the pipe, the flow path and control medium space are entirely separated, and there will never be internal and external leakage, therefore eliminating running, risk, drop, leakage, and so on.

● Low Maintenance Costs

Pinch valves do not have seats, packing, rings, or telescopic tubes that need to be replaced on a regular basis. Only the sleeve needs to be replaced. The valve will be as good as new when the sleeve is changed.
