The DF-series is a stainless steel housing that provides protection not only for ancillaries (e.g. limit switches and solenoid) but also the actuator.

Due to the small size and regular shape of the F-series, the Domed actuator provides a compact package for hygienic or corrosive environments.

Options include:

- Mechanical limit switches
- Proximity sensors
- Solenoids
- LED or mechanical visual indication
- 4-20mA positoner
- ATEX group II category 2

Seven sizes of domes are available in both double acting and spring return, typically to suit ball valves ¼" to 6" (DN6 to DN150) or butterfly valves 1" to 20" (DN25 to DN500)
