Erie By Schneider Electric VT3427H13B020 3-Way Zone Valve 120V 1" NPT Mixing/Diverting

The Erie VT3427H13B020 is a two-position, spring-return zone valve assembly designed for on/off control in closed hydronic heating and cooling systems. This 3-way valve features the PopTop actuator design, allowing for simple installation and field servicing without removing the valve body from the piping.

Key Features:

• 1-inch NPT threaded connection for versatile installation
• 3-way mixing/diverting configuration for multi-zone applications
• 8.0 Cv flow coefficient for efficient water flow
• 120V AC line voltage operation (110V @ 50Hz, 120V @ 60Hz)
• Spring-return fail-safe operation, normally closed to Port A
• Forged brass body construction for durability and corrosion resistance
• ANSI Class IV seat leakage rating (0.01%) for tight shutoff
• PopTop actuator design allows replacement without valve removal
• Maximum system static pressure rating of 400 PSI

Applications:

• On/off control of 4-pipe fan coil units
• Diverting flow from chillers or boilers in hydronic systems
• Zone control in heating and cooling applications
• Hot and chilled water systems with up to 50% glycol

The valve features a nickel-plated stem, brass seat, and Buna N paddle for reliable performance. Suitable for closed-loop systems with fluid temperatures from 32°F to 250°F at 169°F ambient. The actuator mounts above the valve body and can be installed in horizontal or vertical piping configurations. Compatible with 120V thermostats and control systems.
