Magnatrol Solenoid Valves G18A43SC-ACBW Valve

For veteran contractors managing high-demand liquid systems, the Magnatrol G18A43SC-ACBW presents a robust 3/4 inch NPT solenoid valve solution designed for absolute reliability in normally closed (NC) configurations. This Type G full port bronze solenoid valve features a globe pattern body capable of handling fluid temperatures up to 212°F. Engineered for 120V AC operation, this unit is optimized for low pressure and low flow conditions thanks to its specialized Buna-N seating at both the pilot and main orifices, ensuring liquid-tight bubble-tight shutoff. With a maximum differential pressure of 110 PSI and a static pressure limit of 150 PSI, this direct-acting internal pilot-operated valve requires no minimum pressure differential to function, making it indispensable for gravity-fed or low-head pressure applications. The bronze construction provides superior corrosion resistance in diverse process lines, while the G18A43SC-ACBW specific code identifies this as a dedicated "W" series unit for liquid service.

• Full Port Flow Capacity: Delivers a Cv rating of 7.5, minimizing pressure drop across the line even during high-demand cycles.
• No Differential Pressure Required: The internal pilot-operated design ensures the valve opens reliably from zero PSI up to its maximum rating.
• Resilient Buna-N Seals: Optimized for water, oil, and gas applications where tight seating is critical.
• Veteran-Grade Durability: Features a 430 stainless steel plunger and 303 stainless steel pilot valve stem for longevity in industrial environments.
• Versatile Mounting: Designed for horizontal piping installations with the solenoid enclosure positioned vertically on top.

What is the difference between the G18A43SC-ACBW and the standard 18A43?
The "G" prefix indicates a specialized Type G variant designed with Buna-N seating for enhanced performance in low-pressure liquid applications, whereas the suffix "W" confirms its factory-set configuration for liquids up to 212°F.

Can this valve be used for steam or high-temperature hot water?
This specific model is calibrated for liquids less than 212°F. For steam applications, a "S" designated valve with Class H insulation and appropriate seal materials is required to prevent heat-related coil failure.

Is this valve suitable for vertical pipe runs?
No, for proper mechanical operation of the plunger and piston, this Magnatrol bronze valve must be mounted in a horizontal pipe with the solenoid vertical and on top.
