Honeywell American Meter Company 1800C series & 1843CHC Industrial Regulator<\/h3>\n

Introduction<\/h4>\n

Honeywell American Meter Company’s 1800C series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases, suitable for residential, light commercial, and small industrial applications. The 1800C and 1843CHC models can be installed in both horizontal and vertical pipelines.<\/p>\n

Key Features<\/h4>\n
    \n
  1. \u200cWide Range of Valve Body Connection Sizes<\/strong>\u200c: Available in sizes including 3\/4″x3\/4″, 3\/4″x1″, 3\/4″x1-1\/4″, 1″x1″, 1″x1-1\/4″, and 1-1\/4″x1-1\/4″ NPT or BSP-TR.<\/li>\n
  2. \u200cTemperature Range<\/strong>\u200c: -20\u00b0F to +150\u00b0F (-30\u00b0C to 65\u00b0C), adapting to various environmental conditions.<\/li>\n
  3. \u200cThreaded Connections<\/strong>\u200c: Compliant with ANSI B1.20.1 or BS EN 10226 (ISO7) standards.<\/li>\n
  4. \u200cVariety of Interchangeable Orifices and Spring Ranges<\/strong>\u200c: Offering multiple choices to meet different application requirements.<\/li>\n
  5. \u200cOverpressure Shutoff (OPSO) and Underpressure Slam Shut (USO)<\/strong>\u200c: Ensuring system safety.<\/li>\n
  6. \u200cElevation Compensating Orifice<\/strong>\u200c: Suitable for installations where inlet pressure may vary significantly.<\/li>\n
  7. \u200cFull Capacity Internal Relief Valve<\/strong>\u200c: Standard on all models, ensuring safe pressure release under abnormal conditions.<\/li>\n
  8. \u200cSplashguard<\/strong>\u200c: Made of UV-stabilized, weather-resistant resin material, protecting the vent screen from splashes while providing a large external vent opening to keep the regulator functioning properly.<\/li>\n<\/ol>\n

    Technical Specifications<\/h4>\n
      \n
    • \u200cInlet Pressure<\/strong>\u200c: Up to 150 PSIG.<\/li>\n
    • \u200cOutlet Pressure<\/strong>\u200c: 3.5″W.C. to 2 PSIG.<\/li>\n
    • \u200cCompliance<\/strong>\u200c: All models meet ANSI Code B109.4-1998 and CGA Service-Type Regulator Specification CAN\/CGA-6.18-M95 standards.<\/li>\n<\/ul>\n

      Vent Elbow<\/h4>\n

      The regulator vent opening should face downward (6 o’clock position) to minimize the risk of blockage from ice and snow. If this is not possible, a 3\/4″ NPT plastic 90\u00b0 vent elbow (part number 78041P025) and a separate protective screen (part number 70400P017) can be screwed into the vent to provide necessary protection.<\/p>\n

      Options<\/h4>\n
        \n
      • Overpressure shutoff (OPSO)<\/li>\n
      • Underpressure slam shut (USO)<\/li>\n
      • Elevation compensating orifice<\/li>\n
      • Inlet and outlet pressure taps<\/li>\n
      • Vent elbow<\/li>\n
      • Splashguard<\/li>\n<\/ul>\n
