    Control System, General Requirements and Working Principle of Pneumatic Sanitary Valve

    General Requirements for Pneumatic Sanitary Valves The specifications and categories of the production of pneumatic sanitary valves shall meet the requirements of pipeline design documents. The model of the pneumatic valve should indicate the national standard number requirements. If it is manufactured according to enterprise standards, the relevant description of the model should be indicated. The working pressure of the pneumatic sanitary valve is greater than or equal to the working pressure of the pipeline, and without affecting the price, the working pressure that the valve can withstand should be greater than the actual working pressure of the pipeline; either side of the pneumatic valve should be able to withstand…

    An Overview of Sanitary Ball Valve

    Sanitary ball valves are also called as hygienic ball valve which is opened by turning handles attached to balls inside the valves. The ball has a hole or port through the middle. When the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. A ball valve is durable and usually work to achieve perfect shutoff even after years of disuse. Working Principle of Sanitary Ball Valve The Ball valve uses a hollow, perforated and pivoting ball to control flow through it. The ball valve drives the valve handle to…

    7 Points of Pneumatic Butterfly Valve Maintenance

    1. The pneumatic butterfly valve should be kept clean during use, and the transmission threads must be regularly lubricated. When a fault is found, it should be stopped immediately to find out the cause and clear the fault. 2. Packing gland bolts should be evenly tightened, and should not be crooked, so as to avoid injury to prevent stem movement or cause leakage. 3. During installation, the valve can be directly installed on the pipeline according to the connection method. Under normal circumstances, it can be installed at any position in the pipeline, but it needs to be easily accessible for maintenance. Note that the medium flow of the shut-off…

    Classification of Ball Valves by Their Structural Types

    Floating ball valve The sphere of the ball valve floats. Under the effect of medium pressure, the sphere can produce a certain displacement and be pressed tight on the sealing surface at the outlet, ensuring the sealing of the outlet. The floating ball valve has a simple structure and good sealing, but a load of working medium sustained by the sphere is all passed on to the outlet sealing ring. Therefore, one needs to consider if the material of the sealing ring can sustain the working load of the sphere medium. This structure is widely used in medium and low-pressure ball valves. Fixed ball valve The sphere of the ball…
