Product classification
Check valve
Application
A check valve is a type of valve that prevents backflow, ensuring unidirectional fluid flow.
It can be used to protect against liquid back-suction losses and to prevent water hammer in pipelines.
It is used in the food processing, beverage, brewing, oil refining, cosmetics, pharmaceutical, and chemical industries.
Operating Principle
The valve opens when the fluid pressure exceeds the spring’s suction pressure. When the two pressures are equal, the valve closes. A larger pressure differential can also cause the valve to close.
Design and Features
Specification range: 0.5"–4"; DN10–DN100
External construction and shaft: AISI 316L/304
AISI 304 spring
