High Pressure Regulator
Installation, Operation and Maintenance Instructions
Introduction
Table 1. Specifications & Limits
The Fairchild HPD series pressure regulator is
a precision engineered, diaphragm sensing,
pressure reducing regulator designed to
regulate pressure of speciality gases and
liquids. This single stage,low to medium flow
capacity pressure regulator will fullfil pressure
control requirements in analytical, medical and
laboratory instrumentation. The 316 stainless
steel construction and engineered polymer
seals permit the use of both corrossive and non
corrosive media.
