The determining factor of this valve in every aspect of usage, no matter whether the processing involves liquids, fluids or heavy duty and abrasive materials, is the elastomer sleeve. It is the controlling factor of any Air Pinch Valve, not only in respect of usual high performances, but for total versatility in operating in adverse conditions and environments. However, although valve sizing is of a critical priority, the selection of the correct elastomer sleeve for an operation is a maximum priority.
This variety of pinch valve by reason of its unique design and construction does not have competition from other valve types. Some of its primary features and benefits to users of the valve are its inherent abrasive, corrosion and erosive resistant qualities, with the added benefit of non-clogging, maintenance free operation. The Pneumatic operated Pinch Valve provides its users with the ability to seal drop-tight on a flow product, even if the material is in a solid form. However, the influencing elastomer sleeve of this versatile valve is concealed within the outer casing, isolating the product flow from contact with any other part of the valve.
The last one is the valve type and sizing. Over-sizing of valves sometimes occurs when trying to optimize process performance through a reduction of process variability. Over-sizing the valve may hurt process variability in two ways. First, the oversized valve puts too much gain in the valve, leaving less flexibility in adjusting the controller. Best performance results when most loop gain comes from the controller. The second way oversized valves hurt process variability is that an oversized valve is likely to operate more frequently at lower valve openings where seal friction can be greater, particularly in rotary valves.
Sealability and strength property are the most basic and most important characters for all valves. The sealing of a valve can be separated into internal seal and external seal. The front one means the sealing between valve clack and seat. The latter one means the sealing between the moving part of the valve stem and bonnet, body and bonnet, body and connection part. When the valve is used, it should be not only good in sealability but also be safe.

A valve such as this operates the same as a ball valve. This valve contains a flat round plate that is placed in the middle of the pipe, as well as the plate has a bar inside that is joined to a switch in the outer valve portion. This type of valve functions by revolving the handle as well as the plate in similar position or vertical to the movement. Unlike the ball valve type, the butterfly valve is constantly present in the movement; thus there is always a moderate drop in the pressure in the movement regardless of the valve's position.
