Pinch Valves are used popularly in various type of applications due to its specialty of keeping most components outside the liquid flow. The rubber sleeve, which is pinched to control the flow is the only wetted part of this valve. The material grade of the sleeve can vary. The Pinch Solenoid Valves use a solenoid material for the sleeve. The sleeve is connected as part of the pipeline and it is compressed by a metal frame that is attached to a threaded axel. The axel is connected to the handle. The operation of the valve can be manual or automated. The Pinch Control Valves do not block the flow of the material when they are open. As the sleeve can be made at the same internal diameter as the pipes, the flow is completely open. When needed to shut off, the rubber sleeve is pinched by the metal frames.

The volume can be regulated and or stopped completely. However, the Pinch Tube Valves are not suitable for very high pressure, very high temperature systems. The pressure capacities of the valves depend solely on the capacity of the sleeve used. The outside components are made with stainless steel materials. This is also very cost efficient valve because the valve components don’t need to be highly corrosion resistant as they do not get into contact with the material that is flowing. The Hose Pinch Valves use hoses to pinch. There are different sizes and types of valves which are used widely in food processing, pharmaceutical and other industrial applications.
