PR-2 Series Economy Brass Pressure Reducing Regulator
General Details
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 yet it is economical enough to use in low pressure air systems such as instrument cabinet air purge service.
