Sanitary valves generally require GBCCC certification, GB Quality Supervision Bureau certification, and GB Drinking Water Management Committee certification. "Maintaining a flow rate in a corner seat valve can save space. It uses a single acting pneumatic actuator with spring safety protection to operate a guided corner seat valve. When using it, you should choose either normally open or normally closed.". Corner seat valves are widely used for frequent start-up in a short time, with the characteristics of sensitive response and accurate action. When used in conjunction with electromagnetic valves, pneumatic control can accurately control the flow of gas and liquid. It can meet the requirements of accurate temperature control and liquid dripping. The damp heat sterilization cabinet shall be accurately controlled by using corner seat valves to control the amount of steam.

There are many types of sanitary valves in the Chinese market, such as: stainless steel sanitary butterfly valves, three-piece butterfly valves, quick-fit butterfly valves, round screw butterfly valves, pneumatic butterfly valves, stainless steel sanitary diaphragm valves, sanitary pneumatic diaphragm valves, stainless steel sanitary U-tube diaphragm valves, stainless steel sanitary ball valves, dairy ball valves, sanitary ball valves 3P, sanitary ball valves 2P, no dead ends, with ball valves, sanitary clamp ball valves. Stainless steel sanitary check valve, welding check valve, sanitary three-way plug valve, sanitary manual stop valve, T-shaped stop valve, sampling valve, sanitary control valve, sanitary floor drain series and other products

Due to its unique structure, angle valves are difficult to meet hygienic requirements. Strictly speaking, they cannot be used in sanitary production processes. However, for special processes, such as the addition of liquid ammonia during fermentation, cavitation often occurs, and it is difficult to use a single seat globe valve for a long time. Valve manufacturers often recommend selecting angle valves, which can also be tried. After all, it is generally believed that liquid ammonia does not contain bacteria.
