3550 Series Manually Controlled Precision Regulator
1/4 NPT
40 SCFM
150 psig
w/o Gauge
description
Designed for applications that require high flow capacity and accurate process control. A poppet valve, which is balanced by utilizing a rolling diaphragm, ensures a constant output pressure even during wide supply pressure variations. Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube, which adjusts the air supply in accordance with the flow velocity.
