VARIVENT® VACUUM VALVE

Function of the Valve

The hydraulic sizing of vacuum valves is always based on free emptying. Vacuum protection while hot or cold cleaning is not considered.

If a vacuum occurs in the tank system, the valve disc gets lifted by the vacuum. The incoming air flows through the valve from bottom to top. This offers an optimized protection against contamination caused by ingress of pollutant particles. The valve is self drained designed.

The function of the VARIVENT® vacuum valve can optionally be extended with a proximity switch feedback, a pneumatic lifting actuator and a heater.

  • Optimized protection against pollutant particles
  • Ideal combination with the VARITOP® Tank Safety System
  • Fast response time
  • Additional equipment

VARIVENT® vacuum valves are mostly used in combination with VARITOP® Tank Safety System. This makes the brewery industry as main application area.

The optional heater ensures full functionality also below the freezing point, which enables a carefree outdoor application. Just a protection against weather is necessary.

Heater

Heating of a vacuum valve is recommended, when temperatures could reach the freezing point. It ensures that the valve disc will not freeze to the valve seat.

Voltage: 24 V AC, Power: 20 W

 

Pneumatic Lifting Actuator (type A)

The pneumatic lifting actuator lifts the valve disc during the tank CIP to additionally clean the valve seat. So besides the valve housing the seat and gasket surfaces get cleaned as well. The pneumatic lifting actuator can also be installed afterwards.

 

Feedback (type E)

The proximity switch detects the valve position normally closed. As soon as the valve disk leaves the non-actuated position the switching contact is interrupted.

 

Two types of proximity switches are available

Proximity switch 24 V DC M18x1 for type E

2-wire connection

3-wire connection

 

Pneumatic Lifting Actuator and Feedback (type R)

Type R combines the pneumatic lifting actuator type A and the proximity switch type E. Function and application see type A and type E.
