Fairchild HPD1***A**K*N Installation, Operation And Maintenance

Installation, Operation and Maintenance Instructions
Introduction
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.
Features
• Three polymer seat materials provide
media compatility and supply pressure
capability up to 6,000 psig.
• Inconel diaphragm for corrosion
resistance and long life.
• Five outlet pressrue ranges provide
optimum sensitivity
• 20 micron inlet filter
• 0.06 Cv flow coefficient
• Relieving and non relieving designs
• Tamperproof adjustment option
