Description

CK isolating duty, modular design electric actuators are designed for on / off valve types that are infrequently operated. They are designed for use with external controls and motor switchgear. Features • CK isolating duty actuators for infrequently operated on / off valves • Suitable for shut off valves to isolate the site process • Suitable for safety valves for maintenance activities • Modular design means CK actuators can be adapted to meet user specification quickly and efficiently to achieve fast turnarounds and quick delivery • Up to 60 starts per hour at a rate up to 1 start every 6 seconds • Fast and efficient maintenance due to plug and socket connections • Torque measurement and independently adjustable torque limiting for both open and close control
