The 1800B2 Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications.
General Information
Outlet pressures between 3.5" W.C. and 2 PSIG are available. Operating temperature range is -20°F to 150°F (-30°C to 65°C). Maximum flow rate is 2500 SCFH (70.8 m3/h).
All models conform to ANSI Code B109.
4-1998, and CGA Service-Type Regulator Specification CAN/CGA-6.18-M95.
Features
• Variety of interchangeable orifices and spring ranges
• 90 Degree (Right Angle), 180 Degree (Straight-Flow), or Offset Valve Body (See photo on next page)
• Wide range of valve body connection sizes
Options
Vent Elbow
The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not possible, a 3/4" NPT plastic, 90? vent elbow (part number 78041P025) and separate protective screen (part number 70400P017) may be screwed into the vent to provide the necessary protection.
Elevation Compensation
The E.C. orifice is recommended for installations where the inlet pressure may vary over a wide range. The E.C. orifice is available in two sizes: 1/8" x 3/16" and 3/16". The capacities of these orifices are the same as the standard orifice of the same size.
