The PR-2 Series are compact, brass body regulators designed for maximum flexibility in many classes of instrumentation service. Specifically designed for gas applications, this regulator is capable of accepting high pressures directly from cylinders and other high pressure, non-corrosive systems. It is ideally suited for carrier gas pressure regulation, and is economical enough to use in low pressure air systems, such as instrument cabinet air purge service.
