ACTUATOR DESCRIPTION
3.1
General description
The KT-XX-DA series actuators are pneumatic, double-acting
actuators specifically designed to provide efficiency and
reliability in heavy duty services.
The KT-XX-SR series actuators are pneumatic, single-acting
spring-return actuators. These actuators can be assembled
in a ‘spring to open’ or in a ‘spring to close’ configuration.
The spring may be removed from the housing and flipped
to reverse fail direction for flexibility and reducing stock
requirements.
