A pressure regulator is a critical component in any gas or liquid control system. Forward reducing pressure regulators reduce high inlet pressures down to lower outlet pressures. Conversely, back pressure regulators are designed to control inlet pressures. From deep in the depths of the oceans to sky-high in aircrafts, our back pressure and forward reducing pressure regulators cover pressure control from 0.1bar to 1,380bar (20,000psi) and port sizes from 1/8" to 3".
