Product Description
Check vacuum valve
Size: DN25-80&1"-3"
Standard: DIN, 3A, SMS, ISO, IDF
Material: AISI304&AISI316L
Application
To reduce the risk of implosion on vessels which are exposed to a vacuum during both emptying and cleaning regimes?
These units can be fitted to any type of tank or pipe work, the hygienic design of these valves allows them to be used in a large number of applications within the food, beverage and process applications.
Principle
Negative-pressure vacuum valves are spring-loaded safety valve, when the fermentation tank's pressure exceeds negative pressure set pressure value, the tank external pressure (atmospheric pressure) to open the seal seat, inhalation of gas to add the tank pressure;
In order to prevent use in cold regions of the freeze seal seat and seal ring, set up a mandatory open the structure to ensure the valve performance, and can open the valve core CIP cleaning, removing stains fluid within the valve to achieve health requirements.
