Digital positioners that, using piezoelectric technology, have a very low consumption with all the smart features based on the use of microprocessor based electronics.
Limit switches, electronics position transmitter, dome indicator.
The CENTORK positioners can be used in wide range of applications in the process industry. The linear positioners, basically, are incorporated onto pneumatic cylinders being the intelligent pneumatic or electrical control element.
The linear pneumatic actuators are mainly applied to:
• Control of valves.
• Control of dampers.
• Control of hopers, registers, etc.
The quarter tune positioners have been designed, in order to be incorporated onto quarter turn single or double acting pneumatic actuators.
These quarter turn actuators operate on different types of valves: ball, butterfly, plug or dampers.
These valves actuated by a quarter turn actuator with positioner, change from on/off type into modulating type valves.
