Schneider Electric (Erie) VT3427 Valve Body

The Schneider Electric (Erie) VT3427 Valve Body is a robust 1-inch 3-way zone valve engineered for precision control in high-demand hydronic systems. Built with a forged brass body and a nickel-plated stem, this 7.5 Cv valve handles hot and chilled water applications with a static pressure rating of up to 300 psi. Designed as a direct replacement for existing PopTop series installations, the VT3427 features a three-way mixing/diverting configuration that ensures reliable bypass or flow-through operation in terminal units like fan coils and baseboards. The NPT threaded connections allow for a leak-resistant fit, while the paddle-style design provides a high-flow capacity with minimal pressure drop. This two-position valve body is compatible with all AG and AH series actuators, utilizing the signature one-handed release button for tool-free actuator removal and replacement without breaking the line. It serves as an essential component for technicians seeking a primary or secondary terminal unit control solution that facilitates rapid field servicing.

• High Flow Capacity: Features a 7.5 Cv rating, making it ideal for 1-inch line applications requiring high-volume fluid transfer.
• Field Serviceability: PopTop design allows the motorized actuator to be removed with a single hand, simplifying maintenance in tight mechanical spaces.
• Forged Brass Construction: Engineered for long-term durability with a 300 psi static pressure limit and compatibility with up to 50% glycol.
• Versatile Configuration: Operates as either a mixing or diverting valve depending on system orientation to meet specific piping requirements.
• Reliable Seal: Utilizes a Buna N paddle to ensure ANSI Class IV leakage ratings (0.01% of rated capacity) for efficient temperature control.

Is the VT3427 compatible with steam systems?
No, this specific model is designed for hot and chilled water only. For low-pressure steam applications (up to 15 psi), the VS series valve bodies must be used.

Can I install the actuator before the valve body is piped?
For best practices, the valve body should be installed and soldered (if applicable) or threaded into the pipe first. The actuator should be snapped on after the body is secure to prevent heat or mechanical damage during installation.

Does this valve require specific orientation?
This 3-way valve can be mounted in horizontal or vertical piping. However, when installed horizontally, the actuator must be positioned above the valve body to prevent moisture accumulation.
