How does a pneumatic control valve actuator work?
A direct acting pneumatic actuator is coupled to a control valve with a reverse acting plug (sometimes called a ‘hanging plug’). The choice between direct acting and reverse acting pneumatic controls depends on what position the valve should revert to in the event of failure of the compressed air supply. Should the valve close or be wide-open?
How are linear actuators used in motion control?
Linear Actuators Part of a motion control system that produces the desired motion. An actuator is a device that creates physical movement by converting various forms of energy to rotary or linear mechanical motion.
How does the electro pneumatic positioner work on a PS2?
The PS2 Series digital electro-pneumatic positioner with Hart protocol is used to control the final control element of pneumatic linear or part-turn actuators. The electro pneumatic positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to block the valve or to set a safety position.
Which is the best attachment for small actuators?
Integral attachment introduced by SAMSON is the best solution for small and medium-sized actuators as far as safety, cost-effectiveness, quality and a long service life are concerned . A rugged, compact valve unit is created by directly attaching the positioner to the actuator yoke .
When did the first pneumatic positioner come out?
In 1957, we launched the first pneumatic positioner onto the German market . Since then, we have enhanced and perfected our positioners, their attachment and their interaction with a wide variety of valve models and valve accessories .
