IL100-N03 Applications
The IL100-N03 is a 1:1 pneumatic booster relay used when the piping distance between instrumentation and the operating point is long, or the operating area has large capacity, helping accelerate actuation speed considerably by amplifying a low-volume signal into high-volume output while maintaining equal pressure. With 3/8 NPT porting, it suits instrumentation and process-control air lines driving large-capacity actuators or diaphragm valves that require fast, faithful pressure response.
