Erie By Schneider Electric VT3343H13A020 PopTop 3-Way Zone Valve Assembly 3/4" Inverted Flare 24V

The Erie By Schneider Electric VT3343H13A020 is a complete two-position zone valve assembly featuring the innovative PopTop design for easy installation and service in hydronic heating and cooling systems. This assembly combines the VT3343 brass valve body with the AG13A020 24-volt normally closed actuator, providing reliable spring return operation for HVAC and building automation applications.

Key Features:

• 3/4" inverted flare (IFL) retrofit connection for quick installation
• 3-way valve configuration with 4.0 Cv flow coefficient
• 24 VAC power supply at 50/60 Hz (7.5 VA)
• Two-position spring return operation - normally closed to B port when de-energized
• Removable PopTop actuator allows installation after valve body is mounted
• 300 PSI maximum static pressure rating
• ANSI Class IV seat leakage (0.01%) for tight shutoff
• Manual override lever for system flushing and testing
• 25 seconds maximum actuating time at 60 Hz

Construction:

• Forged brass valve body for durability
• Nickel-plated brass stem resists corrosion
• Brass seat with Buna-N paddle
• Stainless steel actuator base plate with aluminum cover
• High-temperature plastic actuator housing

Application: Designed for closed hydronic heating and cooling systems handling hot or chilled water, up to 50% ethylene glycol solutions, or 15 PSIG steam (with high-temperature rated components). Ideal for zone control in fan coils, radiation units, and air handlers. Temperature range: 32°F to 200°F (0°C to 93°C) with AG actuator.

This maintenance-free valve assembly is UL and CUL listed, providing dependable performance in residential and commercial HVAC applications. The synchronous motor-driven spring return mechanism ensures fail-safe operation, returning to the normally closed position when power is removed.
