Welcome to GULEX Techn.-Apparatebau-Vertriebs GmbH in Frankfurt am Main


Your professional partner for valve actuators with a variety of applications and combinations. See for yourself on our website the convincing range of products and services for solving demanding control tasks and implementing reliable control loops.

Valve Actuators

The modularly designed valve actuators are available in various basic designs and many ordering options.

Ball Valve Actuators

Manually and/or directly controllable with standard control devices. Special control devices are not required.

Metering Valves

It is often required to control larger quantities of gases or liquids even at low pressure, reproducibly with a reasonable flow curve.

Since 1980, we have been producing valve actuators in Frankfurt am Main for small control and metering valves, pressure reducers, ball valves, and flaps. Metering and shut-off valves combined with our actuators are also in our delivery program.

Valves from other manufacturers can of course also be operated with our actuators. Feel free to contact us at any time by phone, email, or contact form for personal advice – we look forward to hearing from you!
