Electric Actuated & Motorized Butterfly Valves

1.Choose the Connection Type
Wafer designs save space and weight; lugged valves use threaded mounting lugs; flanged valves provide a rigid bolted connection for permanent piping. Sanitary clamp connections are available for hygienic process systems.

2. Match the Valve to the Medium
Check the medium, operating pressure and temperature before selecting the body, disc and seal materials. NBR, EPDM, VITON and PTFE suit different operating conditions, while PTFE-lined, plastic and metal-seated butterfly valves cover more specialized services.

3. Select the Valve Size and Standard
Confirm the nominal pipe size and applicable flange or connection standard. Available size ranges differ between wafer, lugged, flanged, sanitary and special-material designs.

4. Choose the Electric Actuator
Use ON/OFF control for remote isolation and switching. Choose a modulating actuator when intermediate disc positions are required for general flow adjustment. Supply voltage, feedback signals and actuator torque should be matched to the valve and control system.

5. Check the Installation Environment
Outdoor, washdown or hazardous-area installations may require additional enclosure protection or a suitable certified actuator configuration. Specify these conditions before final actuator selection.
