Ray Murray R622-BCF Second-stage Lp Gas Regulator

Product Description

The RAY MURRAY R622-BCF is a second-stage liquefied petroleum gas regulator designed to reduce intermediate line pressure to a stable appliance-ready delivery pressure. It features a 1/2 inch inlet and 1/2 inch outlet connection and delivers up to 875,000 BTU/h of capacity, making it suitable for high-demand residential and light commercial LP systems. The outlet pressure is adjustable across a range of 9 to 13 inches water column (WC), with a standard delivery setting of 11 inches WC. Licensed gas fitters and plumbers install this regulator as part of a two-stage LP distribution system, where the first-stage regulator drops high tank pressure to an intermediate level and this unit handles the final pressure reduction to the appliance manifold.

This second-stage regulator is used in residential and light commercial propane systems where a two-stage regulation approach is required to maintain consistent appliance pressure regardless of tank level or ambient temperature variation. It is appropriate for installations serving multiple appliances — such as furnaces, water heaters, ranges, and dryers — fed from a common propane supply line. The 1/2 inch NPT inlet and outlet connections are compatible with standard propane distribution piping. This regulator is commonly installed at or near the structure it serves, downstream of the first-stage regulator mounted at the tank.

Key Features

• 875,000 BTU/h capacity supports multi-appliance residential and light commercial propane systems
• Adjustable outlet pressure from 9 to 13 inches WC for flexible system tuning
• Standard delivery pressure of 11 inches WC matches typical LP appliance manifold requirements
• 1/2 inch inlet and 1/2 inch outlet connections fit standard propane distribution piping
• Second-stage design works in tandem with a first-stage regulator for stable downstream pressure

Compatibility

Designed as an OEM-style second-stage LP gas regulator for two-stage propane distribution systems with 1/2 inch NPT piping connections.

Installation Notes

Installation must be performed by a licensed gas fitter or plumber in accordance with NFPA 54, NFPA 58, and applicable local codes. Shut off the propane supply at the tank and verify zero pressure in the line before disconnecting or installing any regulator. The regulator should be mounted with the vent facing downward or in a position that prevents moisture and debris entry, and the vent must never be blocked or capped. Verify outlet pressure with a manometer after installation and before placing appliances back in service.
