Product Overview
The WEA Series Quarter-Turn Electric Actuator converts electrical power into rotary movement for opening and closing valves. It is suitable for valve automation applications where stable electric operation is required without compressed air supply.
Based on the product nameplate, the sample model shown is WEA050 with 220VAC power supply, 0.9A current, 30 second open/close time, 500 N.m maximum torque, and 27 x 27 square output connection. The actuator is suitable for quarter-turn valve operation and can be paired with compatible butterfly valves, ball valves, and plug valves.
Key Features
Quarter-Turn Operation
Designed for 90-degree valve operation commonly used on butterfly valves, ball valves, and plug valves.
Electric Motorized Control
Operates valves using electric power, suitable for systems where pneumatic air supply is not available.
Manual Override
Equipped with manual override mechanism for emergency or maintenance operation when required.
Visual Position Indicator
Top indicator allows easy checking of valve open and close position during operation.
Compact Body Design
Compact actuator housing supports easier installation on valve assemblies and industrial piping systems.
Valve Automation Ready
Suitable for automated control of compatible quarter-turn valves in water and industrial applications.
