Product Description

Pneumatic normally closed pinch valve is designed for larger flow volume bioprocessing and industrial applications. These models output very strong linear forces needed to control fluid in tubing with an instant open or close in tube sizing ranging from 0.187″ – 1.60″ OD. Pneumatic normally closed pinch valve is ideal for pharmaceutical manufacturing systems, single-use Disposable systems, food, and beverage manufacturing where cGMP standards are required. Moreover, panel or base mountable, units can also be configured with optional state sensors, controllers, or set up in normally-open or normally-closed default states. Built-in or available safety caps on larger models are also fitted to address potential finger crushing hazards.

What are the benefits of air-operated pinch valves?

● Product flows naturally with low resistance

The pipe and valve have the same diameter, the structure is novel and simple. And the inner diameter of the rubber sleeve is the same as the pipe, and the local resistance is small. Therefore, the frictional resistance of the air operated pinch valve is extremely small, which will not affect the flow of medium in the pipeline, and it will not cause a blockage. In the nominal diameter range of various air operated pinch valves, the pipeline medium can be almost unobstructed.

● Good tightness and 100% leak-free

Air operated pinch valve series products have no sealing points, the control medium space is completely isolated from the valve channel, and no internal or external leakage will occur. The flat oval housing design ensures that the sleeve of the air operated pinch valve has a specified lip-folding pattern. This special lip-folding method ensures complete sealing of the product flow. Relying on the deformation of the rubber sleeve to achieve opening and closing, even if the fluid contains solid particles or fiber impurities will not block the closure. All things can be completely and quickly wrapped and closed, so the fluid tightly sealed.

    Introduction of Common Valves

    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 »

    The Basis of Valve Selection

    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 »

    The Valve Manufacturing Process and Processing Process

    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 »
