WyeQ+BW Quarter-turn Electric Actuator
一、Product Overview
1.1 Short Description
The WyeQ+BW Quarter-turn Electric Actuator combines a WyeQ multi-turn electric actuator with a BW gearbox to provide high-torque 90-degree rotary operation.
It is designed for ball valves, butterfly valves, plug valves, dampers and other quarter-turn valve applications requiring higher output torque.
1.2 Product Overview
The WyeQ+BW series provides a high-torque electric actuation solution for industrial quarter-turn valves.
By combining the intelligent WyeQ electric actuator with a BW reduction gearbox, the series converts multi-turn actuator output into quarter-turn valve movement while increasing available output torque.
The product range includes eight actuator and gearbox combinations, covering output torque from 1000 Nm to 15000 Nm.
