Maxitrol RV48L Natural Gas Pressure Regulator
Gas Type & Pressure: Natural Gas (NG). Inlet gas pressure: 1/2 psi. Outlet pressure range: 3–6 Water Column. Pipe thread size: 3/4″ Inlet & 3/4″ Outlet FPT. A note emphasizes 1-1/16″ openings for 3/4″ gas pipes. This regulator is designed for NG systems where precise low‑pressure regulation is essential.
Maxitrol 325-5AL-1 1″ Certified Line Regulator
Gas Type & Pressure: Natural Gas. Inlet pressure: 2 psi. Pipe size: 1 inch. Aluminum construction. This model focuses on maintaining stable line pressure for appliances across a range of applications where higher inlet pressure stability is required.
Maxitrol RV48L Liquid Propane Pressure Regulator
Gas Type & Pressure: Propane (LP). Inlet pressure: 1/2 psi. Outlet pressure range: 5–12 WC. Pipe thread size: 3/4″ Inlet & 3/4″ Outlet FPT. Like its NG counterpart, this regulator is configured for precise LP regulation with a 1-1/16″ opening noted for 3/4″ pipes.
Natural Gas Regulator GEIparts
Gas Type: Natural Gas. Inlet pressure: 1/2 psi. Outlet range: 3–5 WC. Pipe size: 3/4″ Inlet & 3/4″ Outlet FPT. Also notes the 1-1/16″ opening requirement for 3/4″ gas pipes, with emphasis on matching pipe openings to regulator openings for correct fit.
Maxitrol RV53-1 1″ Straight-Thru-Flow Regulator
Gas Type & Pressure: Natural Gas. Pipe size: 1 inch. Flow capacity listed as 1,300,000 BTU. Aluminum construction. This straight‑thru model is designed for high‑volume applications where consistent delivery is essential across a wide range of downstream appliances.
Buying Guide: Key Purchase Considerations
- Gas type compatibility: Ensure the regulator is rated for natural gas or propane depending on your system. Some models handle both with adjustment options.
- Inlet and outlet pressure: Verify the inlet pressure your gas source provides and the required downstream outlet pressure for your appliances. Regulators show ranges like 3″–6″ WC or 5″–12″ WC to match these needs.
- Thread size and openings: Most 1″ regulators use 3/4″ FPT threads. Some notes highlight 1-1/16″ openings for 3/4″ pipes, which affects fit. Measure openings before purchasing.
- Material and durability: Aluminum regulators are common for lightweight, corrosion‑resistant installations. Consider the operating environment (outdoor vs indoor) when selecting material.
- Flow capacity: For high‑demand setups (e.g., large BTU loads), check the regulator’s BTU rating or stated outlet range to ensure stable delivery under peak demand.
- Regulator orientation and protection: Some regulators are straight‑through flow; others are designed for specific mounting orientations. Choose models suited to your piping layout and protection needs.
- Safety and certification: Look for regulators manufactured to industry standards and suitable for the gas type and jurisdiction, with clear wiring of inlet/outlet designations.
