Digital Valve Controllers
The introduction of the first Digital Valve Controllers in the mid 1990 was a giant leap forward and one of the most significant improvements in the control valve industry for decades. With the stability of microprocessors and smart technology these controllers have become the dominant replacement technology for conventional and electro-pneumatic positioners. The Fisher® FIELDVUE™ digital valve controllers improve accuracy, dynamic control and provide equipment alerts that gives consistent and predictable knowledge of valve assembly performance and condition improving reliability and safety.
