Resideo V48A2169 Diaphragm Gas Valve 1 Inch 120V

Product Description

The RESIDEO V48A2169 is a solenoid-operated diaphragm gas valve designed for line-voltage applications at 120 volts AC. It features a normally closed configuration with a 1-inch NPT connection and a maximum inlet pressure of 0.5 psi. The valve delivers slow opening and fast closing action, which reduces pressure surges in the gas train and protects connected equipment. Weighing 3.05 pounds and constructed with an aluminum body, it is built for reliable service in commercial and light-industrial gas systems. Licensed HVAC technicians and gas fitters are the primary installers of this valve type.

The V48A2169 is suited for atmospheric boilers, commercial water heaters, and rooftop heating units where line-voltage control of natural gas, LP gas, or manufactured gas is required. The slow-open characteristic makes it appropriate for systems that require controlled gas flow introduction at startup. This valve is rated for line-voltage service at 120 volts AC; applications requiring 24-volt control should reference the V88 series instead.

Key Features

• Normally closed operation ensures the valve defaults to a safe shutoff state on power loss
• Slow-opening, fast-closing diaphragm action reduces gas pressure surges at startup and shutdown
• 1-inch NPT connection fits standard commercial gas train piping
• Compatible with natural gas, LP gas, and manufactured gas
• Line-voltage design rated at 120 volts AC for direct integration with line-voltage control circuits
• Aluminum body construction for lightweight, corrosion-resistant service

Compatibility

Designed for use on atmospheric boilers, commercial water heaters, and rooftop heaters requiring line-voltage gas valve control. This is the V48 line-voltage series; the V88 series is the corresponding 24-volt AC variant.

Installation Notes

Installation must be performed by a licensed gas fitter or HVAC technician in accordance with local codes and the applicable provisions of the IFGC. Shut off the manual gas supply and disconnect line voltage power before removing or installing the valve. Verify inlet pressure does not exceed 0.5 psi before commissioning. Check all connections for leaks with an approved gas leak detection solution before restoring power and gas flow.
