Type Code Of Sanitary Check Valve

Sanitary Check Valve are classified into various types and designations depending on their structure and intended use. The most common types are as follows:

1. H-type Check Valve: This is a simple and reliable check valve with a simple structure and no complex internal parts. It is typically used in low-pressure, small-diameter piping systems.

2. Butterfly Check Valve: This is a check valve that uses a butterfly disc as the switching element. It offers advantages such as a simple structure, reliable sealing, and a compact size. It is typically used in small and medium-diameter piping systems.

3. Piston Check Valve: This is a check valve that uses a piston as the switching element. It offers excellent sealing and a long service life. It is typically used in high-pressure, large-diameter piping systems.

4. Plug Check Valve: This is a check valve that uses a plug as the switching element. It enables fast opening and closing and precise control. It is typically used in high-temperature, high-pressure, and large-diameter piping systems.

5. Pneumatic Check Valve: A pneumatic check valve uses a pneumatic actuator as its driving mechanism. It features strong controllability and flexibility and is commonly used in automatic control systems.

6. Electric Check Valve: A pneumatic check valve uses an electric actuator as its driving mechanism. It offers advantages such as fast response and remote control and is commonly used in intelligent piping systems.
