Electrically Actuated Pressure Regulaton

Using the Fairchild PAX1 electric actuator with pressure regulator provides benefits such as lock-in-last-place, very high reliability, eliminates constant-bleed of omissions, and does not require constant power (only when a change of set point is required).

Example City Gate Pressure Control


Current system includes an I/P transducer with constant bleed of emissions and requiring a constant supply of power.
Current Installation

Upgraded system using the PAX1 instead of an I/P transducer.
Upgraded Installation

Taking it one step further the PAX1 actuator is mounted directly to a Fisher Y600A regulator.
