China Food Grade Pneumatic Pinch Valves are used for material flow interception in pneumatic conveying systems, or other pipelines. In addition, they can be installed as a locking device for silo filling pipes. In the open position the internal cross section of the valve is identical with the connecting pipe diameter.
The air operated pinch valve is pneumatically operated through the air supply connection in the housing. This connection has a G 1/4 inch female thread. The pressurized air compresses the sleeve and provides a shut-off function of the valve. When closed, the sleeve forms a tight seal that will not allow the media leakage. Common industries that utilize pneumatic pinch valves for the benefit of isolating fluid from a mechanical valve including drug dispensing, laboratory equipment, wastewater, medical devices, chemical, food and beverage equipment, ceramic/glass/plastic, and solids handling.

1.Gate valve is the opening and closing body (valve plate) driven by the valve rod, along the sealing surface of the valve seat for lifting movement of the valve, can be connected or stage fluid passage. Gate valve sealing performance is better than the globe valve, fluid resistance is small, openin Read More »
Valve is a control component in the fluid transportation system, the main function is to open and close, regulate, guide, prevent backflow, pressure stabilization, diversion or overflow pressure relief. Valve is also the most complex component in the pipeline, it is generally assembled from multiple Read More »
At first glance, there are not many valve parts, simple structure, and average precision. They are simple parts in the machinery industry, but the core sealing parts of the valve are particularly demanding. The valve manufacturing process is complicated and the technical difficulty is also great. To Read More »
