02 / Valve and actuator selection Select both for the same duty

Select the valve
and actuator together.

Media, pressure, temperature and shut-off requirement define the valve. Available air or electrical supply, operating time, control signal and fail position define the actuator.

03 / Valve and actuator package Scroll to separate both components Static separated component view

01Valve

Select the valve for the process.

Media, pressure, temperature and shut-off requirement determine the body, disc and seat materials.

02Actuator

Match the actuator to the valve.

Choose pneumatic or electric operation, then confirm spring return or double acting operation, the control signal and any manual override.

04 / Example butterfly valve specification Reference data / final selection by duty
