Magnatrol Solenoid Valves G18A44SC-ACBW Valve

The Magnatrol G18A44SC-ACBW is a high-performance 1-inch NPT normally closed solenoid valve engineered for precision fluid control in industrial and commercial HVACR applications. As a direct replacement for the legacy 18A44 series, this Type A full port valve features a rugged bronze body and is optimized for managing water, oil, air, gas, and other non-corrosive liquids at temperatures up to 212°F. Operating on a standard 120V AC coil, this internal pilot-operated valve requires zero differential pressure to open, making it a reliable choice for low-pressure systems and vacuum service. With a maximum differential pressure of 110 PSI and a globe-pattern design for straight-through flow, it ensures minimal pressure drop and high flow capacity. The 18A44 suffix 'W' specifically denotes its compatibility with water and general liquids, providing NEMA 4X watertight protection for demanding environments. For contractors handling industrial solenoid valve replacements, this unit offers the packless construction and continuous-duty performance required for mission-critical process loops.

• Zero Pressure Differential: Operates reliably from 0 to 110 PSI without requiring a minimum pressure drop to open.
• Full Port Design: 1-inch NPT threaded connections with a full port orifice maximize CV flow rates and minimize turbulence.
• Rugged Construction: Cast bronze body with a 303 stainless steel pilot valve and 302 stainless steel springs for long-term service.
• Standardized Replacement: Modernized replacement for the 18A44, F18A44-W, and alternate G18A44 series models.
• Environmental Rating: Equipped with a NEMA 4X enclosure, providing superior protection against moisture and corrosion in wet locations.

What fluids are compatible with the G18A44SC-ACBW?
This valve is designed for liquid service up to 212°F, including water, brine, solvents, and gas. For steam or high-temperature liquids up to 400°F, refer to 'S' or 'H' suffix models.

Does this valve require a minimum pressure to function?
No. As an internal pilot-operated valve with a direct-lift design, it functions at zero PSI, making it ideal for gravity-fed or low-head pressure applications.

Can the coil be replaced without removing the valve from the line?
Yes, the Magnatrol solenoid architecture allows for the coil and internal components to be serviced while the bronze valve body remains inline, reducing system downtime.
