EL-O-Matic Posiflex Positioners
The EL-O-Matic Posiflex positioners consists of two models, the pneumatic F10 and the electro-pneumatic F20.
Both models can be used in applications in which the pneumatic actuator must be positioned with a high degree of accuracy and are suitable for both single and double acting. The modular structure can be simply extended with pressure gauges, various switches or position transmitter options.
