Schneider Electric (Erie) VS3427G14A020 Valve Assembly

The Schneider Electric Erie VS3427G14A020 Valve Assembly is a heavy-duty, 3-way zone valve engineered for high-demand hydronic and low-pressure steam applications. Rated for 15 PSI steam and fluid temperatures up to 250°F, this assembly utilizes a 24Vac spring return actuator (AG14A020) to ensure a reliable fail-safe position during power loss. With a high flow capacity of 8.0 Cv and 1" NPT threaded connections, it provides the low pressure drop required for large residential or light commercial fan coil and baseboard systems. The forged brass body and nickel-plated stem are specifically designed to resist scaling and corrosion in closed-loop systems. As a genuine Erie PopTop series valve, the actuator can be removed with a single button press, allowing for rapid maintenance or replacement without breaking the line. This two-position steam zone valve is the standard for contractors seeking a normally closed diverting or mixing solution that balances high thermal resistance with a compact footprint.

• Steam Rated Durability: Specifically built to handle 15 PSI low-pressure steam and high-temperature hydronic fluids without paddle degradation.
• PopTop Actuator Logic: The 24Vac AG series actuator features a spring return fail-safe and a manual override lever for easy system flushing and commissioning.
• Optimal Control: A high 8.0 Cv rating ensures efficient flow through 1-inch piping, reducing pump head requirements and improving system energy efficiency.
• Simplified Service: The tool-free actuator removal system significantly cuts labor time during maintenance cycles or troubleshooting.

• Can this be used in open systems? It is highly recommended for closed hydronic loops. Open systems with high oxygen or chlorine levels can lead to premature failure of the internal components.
• How should the valve be oriented? For optimal performance, the valve can be mounted in vertical or horizontal piping. If horizontal, the actuator must be positioned above the forged brass body to prevent moisture damage.
• Is an end switch included? This specific model is a 2-wire setup; verify your control circuit requirements if your system utilizes specialized end-switch signaling for boiler or pump staging.
