Asco 8214260 Csa Ac 120/60,110/50 D Gas Shutoff Valve

Product Description

The ASCO 8214260 CSA AC 120/60,110/50 D is a 2-way, normally closed solenoid valve engineered for gas safety shutoff applications. It operates on dual-rated AC power at 120/60 VAC or 110/50 VAC, making it compatible with both North American and international supply voltages. The valve body is constructed from aluminum and uses a Buna N seal for reliable performance with fuel gas media. With a Cv of 32 and a 1-1/4 inch NPT pipe connection, it is sized for moderate-flow gas lines in residential and commercial heating systems. Licensed HVAC technicians and gas service professionals are the primary installers of this type of safety shutoff device.

This valve is used in gas safety shutoff applications where a normally closed, de-energize-to-close design is required. Typical installations include gas trains on commercial burners, rooftop units, boilers, and other fuel gas systems operating at pressures up to 5 psi. The 1-1/4 inch NPT connection suits standard gas line sizes found in light commercial and larger residential heating equipment. The NEMA 1 enclosure rating makes it appropriate for indoor, protected installations.

Key Features

• Normally closed operation — valve closes automatically when de-energized for fail-safe gas shutoff
• Dual voltage rating: 120/60 VAC and 110/50 VAC for flexible power supply compatibility
• Aluminum valve body for lightweight, corrosion-resistant construction
• Buna N seal material rated for compatibility with fuel gas media
• 1-1/4 inch NPT connection with a Cv of 32 for moderate-flow gas lines
• NEMA 1 enclosure rating for standard indoor installations

Compatibility

Designed as an OEM-style gas safety shutoff solenoid valve for fuel gas systems requiring a 1-1/4 inch NPT, normally closed, 2-way valve at 120/60 or 110/50 VAC. Suitable for use with fuel gas media at pressures from 0 to 5 psi and media temperatures up to 125 degrees F.

Installation Notes

Installation of gas shutoff solenoid valves must be performed by a licensed HVAC technician or gas service professional in accordance with IFGC requirements and local codes. Shut off the gas supply and de-energize the circuit before beginning any work. Verify that the supply voltage matches the valve rating before energizing. The NEMA 1 enclosure is rated for indoor use only — do not install in locations exposed to moisture or outdoor conditions.
