RegOฎ 1780 Series Heavy Duty Gas Line Regulator |

|
The 1780 Series Regulators are designed for final line pressure regulation on gas distribution systems. They are suitable for a variety of gases in medical or industrial applications. The 1780 Series Regulators have a balanced seat, are constructed with oxygen compatible materials, and have the same valve design, brass body, and internal parts as the premium BR-1780 Series. Flow performance is likewise equal to the BR-1780 Series. Features ท Maintains a steady downstream pressure across a range of inlet pressure commonly provided by a cryogenic bulk tank. ท Large seat and diaphragm areas provide high capacity with sensitive control of delivery pressure with low falloff. ท Two 1/4" FNPT delivery pressure gauge ports are located (plugged) on each side of the valve. ท Two bonnet drain/vent holes to allow for different mounting orientation. ท T-handle adjusting screw. ท Maximum inlet pressure is 400 psig. ท Available in three delivery pressure ranges. ท Temperature range: -40 F to 165 F. ท Cleaned per CGA G-4.1 for oxygen service.
