FAQ

What is the basic operating principle of a pinch valve?

Pinch valves regulate fluid flow by squeezing a flexible sleeve along the centre line. When open, they provide a full, unrestricted bore.

What are the main components of a pinch valve?

The valve comprises three key parts: the body, an internal rubber sleeve, and end connections. The sleeve, which closes the valve when compressed, is wear-resistant, absorbing impact energy and returning to shape.

What are the advantages of pinch valves over traditional valve types?

Benefits include low maintenance, a compact design, quick operation, self-cleaning, tight shutoff, and minimal turbulence. Only the rubber sleeve needs periodic replacement.

What is the typical operating temperature and pressure range for pinch valves?

Standard models operate up to 250°F, with special versions for temperatures from -100°F to 550°F. Pressure ratings depend on valve size, ranging from 100 psig for 1-inch valves to 15 psig for 12-inch ones, with special models reaching 300 psig.

What industries commonly use pinch valves?

Pinch valves are commonly used in wastewater treatment, cement, mining, food and beverage, medical, and pharmaceutical industries, particularly for handling slurries, powders, and abrasive materials.
