Manufactured by Bailey Birkett, the G4 series of pilot operated pressure reducing valves provide extremely accurate levels of pressure regulation for steam, air and industrial gas applications. The valve relies upon a stable pressure signal from the outlet pipework in order to maintain stable control of the outlet pressure. Type Pilot Operated Size & Connections DN15 to DN50 • PN40 Flanged (PN16/25, ANSI 150/300 & BST F/H on request) Duty Air • Gases • Steam Materials Bronze Body • Stainless Steel Trim* Upstream Pressure Range 0.7 to 35 Bar (dependent on duty) Downstream Pressure Range 0.07 to 21 Bar Temperature -20°C to 260°C (dependent on trim, see datasheet for details) Spares Routine & Full Repair Kits Available – Available in our webshop * Option of PTFE • Nitrile (31 bar max) • FKM (31 bar max)

Designed for installation on potable water lines to protect against both backsiphonage and backpressure of contaminated water into the potable water supply. Assembly shall provide protection where a potential health hazard exists.
