Key Parameters Category Parameter Description / Typical Values Pressure Ratings Maximum Inlet Pressure (P1) 5 psig (0.34 bar) for standard models. Outlet Pressure (P2) Range Adjustable within a range, typically from 3.5" w.c. to 14" w.c. (0.87 to 3.5 kPa) or other similar low-pressure ranges. Specific models cover different ranges. Outlet Pressure (P2) Rating Maximum 2.0 psig (0.14 bar). Capacity Flow Coefficient (Cv) Low Cv, suitable for small lines and low flow rates. Example: Cv ~0.3. Maximum Flow (Natural Gas) Typically around 200 CFH (Cubic Feet per Hour) for natural gas, depending on inlet/outlet conditions. Connections & Size Pipe Size Typically 1/2 inch NPT inlet and outlet. End Connections Female NPT (National Pipe Taper). Materials Body Material Aluminum or Zinc Alloy. Internal Components Stainless Steel, Rubber Diaphragm. Environment Operating Temperature Standard for indoor/outdoor conditions (e.g., -20°F to 150°F / -29°C to 66°C). Applicable Fluids Natural Gas, Air, and other non-corrosive, clean gases.
