Gas pressure regulator HPD

diaphragmPEEKstainless steel 316L

Product overview
The Rotork Fairchild HPD is a high-pressure regulator designed to reduce very high supply pressures to a controlled lower output pressure. Constructed from rugged 316L stainless steel for corrosion resistance and durability, the HPD is available in 2-port or 4-port configurations and supports a range of gases and operating temperatures through selectable seat materials.

Features

• Standard X-750 Inconel diaphragm
• Three seat material choices: PEEK, CTFE, Vespel
• Tamper-proof option available
• Five output pressure ranges from 0–25 psi / 0–1.7 BAR / 0–170 kPa up to 5–500 psi / 0.35–35 BAR / 35–3500 kPa
• Supply valve Cv: 0.06
• Panel-mounting option
• Increased gas throughput compared with standard regulators
• Corrosion-resistant construction compatible with most gases
• Multiple seat options for chemical compatibility and extended temperature range
• Patented valve and valve seat design to reduce leakage
