Schneider Electric (Erie) VM3427 Valve Body

The Schneider Electric (Erie) VM3427 Valve Body is a rugged, 1-inch 3-way modulating zone valve engineered for precision flow control in hydronic HVAC systems. Built with a forged brass body rated for 300 psig, this valve is designed for high-demand applications like fan coil units and VAV reheat. Its 8.0 Cv rating provides linear flow characteristics, ensuring stable domestic hot water or chilled water delivery. As part of the Erie PopTop series, it features a quick-release mounting system that allows for actuator removal without draining the system, significantly reducing service labor. This NPT threaded valve meets ANSI Class IV leakage standards, providing a tight close-off of up to 35 psi. For contractors managing commercial hydronic loops, the VM3427 offers a reliable, low-maintenance solution for proportional mixing or diverting needs, compatible with high-temperature media ranging from 32° to 200°F.

• Forged Brass Durability: Rated for up to 300 psig static pressure, ensuring long-term performance in high-pressure commercial loops.
• Efficient Serviceability: The PopTop design allows for one-handed actuator attachment and removal, streamlining maintenance and replacement.
• High Flow Capacity: An 8.0 Cv flow coefficient supports larger zones with minimal pressure drop across the valve body.
• Superior Sealing: Achieves ANSI Class IV seat leakage status (0.01% of rated capacity) for effective shut-off and energy efficiency.

• What actuators are compatible with the VM3427? This valve body is designed to pair with Schneider Electric AT (tri-state) or AP (proportional 0-10 VDC or 4-20 mA) series modulating actuators.
• Can this valve be used for steam applications? No, the VM3427 is specified for hot or chilled water and glycol solutions (up to 50%) and is not rated for steam service.
• Is the flow characteristic linear or equal percentage? For this specific 8.0 Cv model, the flow characteristic is linear, offering predictable performance across its modulation range.
