Magnatrol Solenoid Valves G131S44SC-ACTS Valve

The Magnatrol G131S44SC-ACTS is a high-performance, 1-inch NPT normally closed solenoid valve specifically engineered for demanding steam flow control applications. This veteran-preferred unit serves as a direct upgrade for the discontinued 131S44 model, featuring a full port bronze body and a globe pattern design that ensures maximum flow capacity. Operating with a 120V AC coil, this internal pilot-operated valve requires zero differential pressure to actuate, making it a reliable solution for low-pressure steam systems up to 180 PSI and fluid temperatures reaching 400°F.

For contractors managing industrial boiler controls, the "S" designation in the part number G131S44SC-ACTS confirms the internal Teflon orifice seals and stainless steel wetted parts are optimized for steam. The packless construction eliminates the need for external stuffing boxes, significantly reducing potential leak points in the field. To maintain long-term piston assembly performance, ensure your system is filtered to remove sediment, as small particles can interfere with the tight clearances required for zero-pressure solenoid operation. This valve must be installed in a horizontal run with the solenoid enclosure in the vertical position for optimal seat alignment.

• Universal Compatibility: Serves as the primary replacement solenoid valve for the legacy 131S44 series in steam service.
• Industrial Build: Heavy-duty cast bronze valve body rated for 200 PSI static pressure and high-temperature environments.
• Reliable Actuation: Normally closed operation with an encapsulated Class H coil designed for continuous duty cycles.
• Zero Differential Performance: Pilot-operated mechanism functions effectively even without a pressure drop across the valve.

Common Questions

What is the difference between the G131S44S, H, and W models?
The suffix indicates the media compatibility: "S" is for steam, "H" handles hot liquids up to 400°F using specialized seals, and "W" is for water or standard liquids below 212°F.

What mounting orientation is required for this steam valve?
Technicians should always install the G131S44SC-ACTS in a horizontal pipe run with the solenoid coil positioned vertically on top to prevent the piston from sticking due to gravity or debris.

Does this valve require a minimum pressure differential to open?
No, this is a zero-pressure solenoid valve, meaning it will actuate and stay open regardless of the system pressure, provided the coil is energized with the correct 120V signal.
