Application\u200c:<\/strong>
\nThe 1784 Series Heavy Duty Gas Line Regulators are engineered for final line pressure regulation in gas distribution systems. Designed for medical and industrial applications, they accommodate a variety of gases. Key attributes include a balanced seat design, oxygen-compatible materials, and a valve construction mirroring the premium BR-1780 Series\u2014featuring a brass body and internal brass components. Flow performance matches the BR-1780 Series, ensuring reliability.<\/p>\n

Pressure Stability\u200c: Maintains consistent downstream pressure across varying inlet pressures, typical of cryogenic bulk tanks.
\nHigh Capacity & Control\u200c: Large seat and diaphragm areas enable sensitive pressure control with minimal falloff.
\nGauge Ports\u200c: Equipped with two 1\/4\u201d FNPT delivery pressure gauge ports (plugged) on each side of the valve.
\nVersatile Mounting\u200c: Includes two bonnet drain\/vent holes for flexible orientation.
\nAdjustability\u200c: Features a T-handle adjusting screw for precise pressure tuning.
\nRobust Specifications\u200c:
\nMaximum inlet pressure: 435 psig (30 Bar).
\nAvailable in four delivery pressure ranges (A-D).
\nOperating temperature range: -40\u00b0F to +165\u00b0F (-40\u00b0C to +74\u00b0C).
\nOxygen Service Ready\u200c: Cleaned per CGA G-4.1 standards.
\nQuality Assurance\u200c: 100% factory tested for performance.
\nMaterials\u200c<\/p>\n

Body\u200c: Forged brass.
