The pneumatic vesicular valve is a valve that controls the fluid flow through the deformation of a flexible component: the sleeve. Sleeve deformation can take place directly and pneumatically or by mechanical compression. The actuation of these valves, the pinching action, is accomplished by air or hydraulic pressure placed on the sleeve. Modulating the air pressure within the annular space between the body and the sleeve can open, throttle, or close the valve. The valve body acts as a built-in actuator, eliminating costly pneumatic, hydraulic or electric actuators.
When the control medium is not input, the cavity between the rubber sleeve and the valve body is in communication with the atmosphere, and the rubber sleeve is in an outward tension state under fluid pressure. Because there are reinforced plies arranged at a certain angle in the sleeve, the axial and radial pressure of the sleeve are balanced with each other, so the length and diameter of the sleeve will not change due to fluid pressure. When the control medium enters the cavity between the pipe sleeve and the valve body, the pipe sleeve is deformed and blocked under the pressure of the medium.

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 »
