Rotork has announced that it has acquired K-Tork International Inc. providing a significant additional scope of supply to the product portfolio of the company. K-Tork vane-type pneumatic actuators and Type K damper drive systems are well established in many industries and utilities.

The simple one-moving-part design provides accurate modulating control and long term service life in high-cycle applications. K-Tork valve actuators are suitable for ball, butterfly and plug valves and can be retrofitted to existing valve installations. The range includes double-acting and spring-return options, manual overrides, open/close and modulating controls.

Type K damper drives are designed to control the combustion air and flue gas on power generation boilers, steam boilers, furnaces and process heaters. They are designed as “drop in place” replacements for many older generation damper drives and will interface with conventional or bus network control systems.
