    How Does Sanitary Diaphragm Valves Work?

    Sanitary diaphragm valve is a special form of cut-off valve. It’s opening and closing parts is a diaphragm made of soft material to separate the inner chamber of the valve body from the inner cavity of the cover and the driving parts. Sanitary diaphragm valve is widely used in hygienic winemaking, dairy products, beverages, and other food industry as well as the pharmaceutical field of aseptic conditions, to achieve the control of pipeline fluid and open/close tasks.

    How to Maintain the Sanitary Diaphragm Valves?

    In the previous article An Overview of Diaphragm Valves, you have already known what the diaphragm valve is. Its opening and closing part is a piece of the diaphragm made of soft material, which is used to separate the body cavity, cover cavity and the drive parts. Sanitary diaphragm valves is a special type of diaphragm valve which has higher specifications and is safer and more hygienic. The main material of sanitary diaphragm valves is stainless steel. Although the stainless steel sanitary diaphragm valve has a better performance than the ordinary valve, one thing similar is that all kinds of valves have a service life and maintenance cycle. Regular maintenance…

    Pros and Cons of Diaphragm valve and Globe Valve

    Diaphragm valve Diaphragm valves consists of a valve body with two or more ports, a diaphragm, and a “weir or saddle” or seat upon which the diaphragm closes the valve. The diaphragm valve was initially developed for industrial applications and pipe-organs. Later on the design was adapted for use in the bio-pharmaceutical industry by using compliant materials that can withstand sanitizing and sterilizing methods. What’s more, sanitary diaphragm valves are specially designed with the highest standard for applications in manufacturing of medicine and food. Diaphragm valves use a corrosion-resistant lining valve body and a corrosion-resistant diaphragm to replace the valve plug components, and control the medium by moving the diaphragm.…

    An overview of Diaphragm Valves

    The diaphragm valve, structurally different from the general valve, is a special type of shut-off valve. Its opening and closing member is a diaphragm made of soft material (elastic, corrosion-resistant, non-permeable material such as rubber and plastic), which separates the valve body cavity from the bonnet cavity and the driving member. Diaphragm valves can be used for low pressure, low temperature, corrosive and suspended materials. They have the advantage of simple structure, good sealing and anti-corrosion performance, and low fluid resistance, so it is widely used in various fields. Diaphragm Valve Classification -According to the structure, there are ridge type, cut-off type, ram type, etc.; -According to the driving method,…
