The Rotork Fairchild HPD is a High Pressure Regulator designed for applications that have high supply pressures and require a much lower output pressure. It is constructed of rugged 316L Stainless Steel for corrosion resistance and durability. The HPD is available in a 2 or 4 port configuration.
HPD Style Regulators
This model features standard Inconel diaphragms to eliminate drift and provide long term accuracy and stability. With 2 or 4 ports and standard NPT, BSPT or SAE style port threads, five available output ranges allow selection from 0-25 psi to 0-500 psi.

Q & A
HPD High Pressure Regulator Q & A
+What is the maximum supply pressure for the HPD regulator?
The HPD can handle up to 6,000 psig (414 bar) on its inlet, depending on the seat material.
+What output (regulated) pressure ranges are available?
There are five output ranges: 0–25 psi, 0–50 psi, 1–100 psi, 2–250 psi, and 5–500 psi.
+What materials are used in the HPD’s construction?
The body and housing are 316L stainless steel. The supply and internal valves are 316L stainless steel. The diaphragm is an Inconel Alloy X-750.
+What seat materials are available, and how do they affect performance?
The HPD offers three seat materials: PEEK, CTFE, and Vespel. Each has different maximum temperature and pressure ratings: for instance, PEEK supports up to 6,000 psig at 175°F.
+What is the temperature range for the HPD?
The ambient temperature range is –40 °F to +500 °F (–40 °C to +260 °C), though actual limits depend on the seat material.
