Electric On / OFF Valves
Electrically operated RF Valves® are supplied with all major electro-mechanical actuators, such as EIM, Rotork, Limitorque, and Auma.
Smaller electric actuated valves up to 3” ID are available in more compact designs.
Important Economies:
Standard control packages may offer important economies versus pneumatic actuators, when the cost of accessories, installation, and maintenance is carefully evaluated for both designs.
Standard features of On-Off electric actuators include:
- Manual hand wheel override
- Fail last position @ loss of power with self-locking worm gear
- Open/Close torque limit switches
- Local push-button control and remote actuation capability
- Direct interface with mA current and digital signals
- Phase sentry
- All connections made within central, protected control box
- 110~560VAC, Single or 3-Phase, 50~60Hz
Optional features include remote control, PLC integration and extended shafts.
Design Features include:
- Industry Standard face-to-face dimensions making them interchangeable with most ball valves, plug valves, gate valves, and diaphragm valves
- Patented non-stretch elastomer tube design, providing a longer tube life and operation under vacuum conditions
- Split valve body design, combined with elastomer tubes that have no flange bolt holes, allow in-line tube change that drastically reduce maintenance time
- Stainless steel shafts, screws, pull bars and fasteners on all electric on-off valves
- Exterior as well as interior corrosion resistant coating
