Schneider Electric (Erie) VT3427G13A020 Valve Assembly

The Schneider Electric Erie VT3427G13A020 Valve Assembly is a professional-grade 3-way zone valve designed for demanding hydronic heating and cooling systems. Built around the industry-standard Erie PopTop platform, this unit features a 1-inch NPT connection and a robust 7.5 Cv flow coefficient, making it ideal for fan coil and baseboard radiator applications where high flow capacity and reliable two-position control are required. The 24Vac spring return actuator ensures a fail-safe normally closed position upon power loss, providing critical system protection without the need for complex linkages.

Engineered for technical efficiency, the VT3427G13A020 utilizes a hysteresis synchronous motor to drive the valve paddle against the return spring, maximizing life cycles in high-traffic commercial and residential loops. The forged brass body and nickel-plated stem offer superior corrosion resistance, while the normally closed configuration and 18-inch appliance leads allow for straightforward integration into existing control circuits. This assembly is rated for a maximum static pressure of 400 psi and is compatible with hot or chilled water and up to 50% glycol solutions.

• Tool-less Actuator Removal: The iconic PopTop design allows for quick head replacement without breaking the plumbing line or using specialized tools.
• High Flow Efficiency: A 7.5 Cv rating ensures minimal pressure drop across the 1-inch NPT ports in 3-way mixing or diverting configurations.
• Fail-Safe Operation: Mechanical spring return functionality guarantees the valve returns to the closed position during power interruptions.
• Durable Construction: Forged brass body with BUNA N paddle seals provides a tight ANSI Class IV leakage rating for long-term reliability.

Can the actuator be replaced without draining the system?
Yes, the Erie PopTop series is specifically designed for quick-release actuator removal, allowing for electrical service or motor replacement while the valve body remains pressurized and in-line.

Is this valve compatible with steam applications?
No, this specific VT series model is rated for hot and chilled water up to 200°F. For low-pressure steam applications up to 15 psi, the VS series equivalent should be utilized.

What is the maximum close-off pressure for this 1-inch assembly?
This 7.5 Cv assembly is rated for a close-off pressure of up to 17 psi with the standard AG actuator provided in this configuration.
