The Fairchild Model 4514A is a high-capacity pneumatic volume booster specifically engineered to enhance the stroking speed of large control valves. It operates on a 1:1 signal to output ratio, using a low-volume pneumatic signal to control a high-volume, high-pressure output. Known for its rapid response and high flow capacity, the 4514A ensures stable and precise operation even in demanding industrial environments. Its robust construction and versatile design make it an ideal choice for applications requiring fast valve actuation and reliable process control.
