Electrical Rotary Actuator
Self-contained quarter-turn electric actuator — QT-E/F, QT-A/B/C/D and high-torque QTR series.
Electrical Rotary Actuator
Our electrical rotary actuator range automates ball, butterfly, plug and damper valves across three model families — the compact low-torque QT-E/F series, the QT-A/B/C/D series, and the high-torque three-phase QTR series — each built on a die-cast/powder-coated aluminium body with a single blank gear-pinion reduction unit for smooth, reliable quarter-turn output.
Every actuator carries a transparent position-indicator dome for at-a-glance open/close status, adjustable travel limit switches, and accepts both simple on/off changeover-contact control and 4–20 mA / 0–10V proportional control from a PLC, DCS or PID loop. The QTR series additionally includes a manual declutch lever for safe hand operation during a power failure.
Engineered For Reliable Performance
