Many industries use specific valves, called pinch valves, to control fluids, slurries, abrasives and corrosive chemicals. Pinch valves, available from Rhinoflex Pinch Valves , are constructed of a heavy-duty, rugged pinch mechanism that positions a sleeve. The valve offers maximum durability and ensures precise flow control in many industrial processes.

Inside every pinch valve there is a sleeve that is crucial to the performance success of the valve. This sleeve enables a pinch valve to have a bi-directional, drop tight shut off with which to control flow. Most pinch valve sleeves are made of flexible elastomer compounds, many of which resemble rubber in composition and feel. Because a sleeve's composition is crucial to the success of the valve's application, valve manufacturers offer different elastomer options from which the sleeve can be constructed.

Pinch valves are useful in a wide range of industries. The ability of a purchaser to choose the desired sleeve composition is paramount. Commonly used in the mining industry, a pinch valve's tough construction makes it suitable for use on harsh and abrasive mining slurries. Pinch valves can also be useful in demanding wastewater treatment applications. For example, a pinch valves accurate, repeatable linear flow control and drop tight, bi-directional shut off make this valve type a good choice for sludge and raw sewage control.

In the power industry, pinch valves are an important component used in lime and ash handling, commonly found two tough services. The abrasion-resistant, self-cleaning, and flexible elastomer sleeve of a pinch valve would not scale, bridge, plug or freeze on slurries. Pinch valves can also work in the treatment and handling of corrosive chemicals. Because there is no packing to maintain and no cavities, seats, or cam action to bind valve operation, pinch valves are often used in corrosive chemical applications.

Pinch valves can also be used in pulp and paper mills. Pulp stock, coating and recycled paper lines are some of the difficult applications for a valve. The flexible elastomer sleeve of a pinch valve is able to withstand these abrasive services. Pinch valves can also be a great asset in food and beverage plants, sand/silica factories, refineries, pneumatic conveying, and scrubbing.
