SPA-L Pneumatic Actuator, Bonnet Type

The SPA-L Bonnet pneumatic actuators are designed for the reliable operation of on/off and control valves. Their robust, modular design—which includes various actuator sizes and spring combinations—along with the option to add positioners and limit switches, makes them a versatile solution for industrial applications.

Main Features

Modular design for flexible configurations

The modular design allows for adaptation to different requirements. Various actuator sizes, spring combinations, and strokes offer flexibility in design.

Rugged design for industrial applications

The drive housings are made of coated steel as standard. Versions in stainless steel or electrolytically polished stainless steel are available as options.

Flexible adaptation to the fixture

The length and spacing of the pillars can be selected to suit the specific application. The coupling connects the drive spindle to the valve spindle.

A wide range of control and feedback options

With the right accessories, such as solenoid valves, limit switch boxes, and pneumatic or electropneumatic positioners, the actuator can be adapted to various control and regulation requirements.

Expandable equipment for operations

Optional accessories such as minimum and maximum stroke limiters, manual emergency controls, silencers, and exhaust dampers allow for application-specific configurations.
