Control Top
Safe control and monitoring of overflow valves in breweries, dairies, fruit juice production plants and in the pharmaceutical industry.


The T.VIS® Q-15 is equipped with a valve-specific proximity switch for position detection in the lantern. The necessary wiring for control and feedback is carried out via an externally accessible M12 connector. Thanks to the initial initialization carried out at the factory, the only required adjustments for operation are to be made on the proximity switch. The buttons located inside the T.VIS® can be used for reinitialization after a reset. The push buttons are secured electronically against inadvertent or incorrect operation, while in operating mode. The supply air connection is equipped with a replaceable filter to protect the built-in solenoid valves.


Equipped with a high-precision path measuring system, the T.VIS® A-15 offers automatic open/close position recognition on any valve, which can be equipped with a T.VIS® control top.

The T.VIS E-20 is the perfect control top to be used in explosive gas and dust atmospheres.

The control top GEA T.VIS® M-20 offers the entire range of modern control functions required in the majority of application points, plus additional advantages in terms of automated valve commissioning and efficient equipment management.

The T.VIS® P-15 is a compact position controller for pneumatic process valves. The position is detected by a position sensor and adjusted by two integrated solenoid valves.
