The Erie By Schneider Electric VT3327H13A020 is a two-position spring return zone valve designed for closed hydronic heating and cooling systems. This 3-way normally closed valve features a 3/4" NPT threaded connection and operates on 24VAC power, making it ideal for residential and light commercial HVAC applications.

Key Features:

• Forged brass valve body with nickel-plated stem for durability and corrosion resistance
• Buna N paddle for reliable sealing performance
• ANSI Class IV seat leakage rating (0.01%) for tight shutoff
• PopTop design allows actuator replacement without removing valve body
• System static pressure limit: 400 psi (2758 kPa)
• Suitable for hot and chilled water applications, up to 50% glycol mixtures
• Spring return operation ensures fail-safe positioning when power is removed
• Can be mounted in horizontal or vertical piping configurations

This valve is designed for use in closed loop hydronic systems and provides reliable flow control for zone heating and cooling applications. The normally closed configuration means the valve closes when de-energized and opens when powered, making it suitable for safety-critical applications. Compatible with thermostats and building automation systems for precise temperature control.
