Ball valve actuators
The modularly designed ball valve actuators are available in various basic designs and many order variants. Users can select their device using the following order codes.
- Simplest control through built-in motor controls.
- Manually and/or directly controllable with standard control devices. Special control devices are not required.
- With position sensors, the actuators are internally electronically controlled and reversible to positions 1, 2, 3, and 4.
- For control, only 1 potential-free contact and 1 pulse of at least 1 ms are needed per switching position.
- Continuous contact occupation during the switching process is also possible.
- Internal end position shutoff and feedback.
- Pulse-controlled rotation (toggling) to the OPEN or CLOSED position to prevent pressure surges is available as an option.
- Special rotation angles available upon request.
- Standard fittings up to DN 20 can be combined with the actuators.
