Erie By Schneider Electric VT2221G23A020 Zone Valve NPT HVAC Control Valves & Actuators - 2-Way 1/2 24V

The Erie by Schneider Electric VT2221G23A020 is a 2-way normally open (N/O) zone valve designed for use in closed hydronic heating and cooling systems. This electric zone valve features a 1/2-inch NPT threaded connection and operates on 24 volts AC, making it ideal for residential and light commercial HVAC applications.

Key Features:

• 1/2-inch NPT threaded pipe connections for standard installation
• 2-way normally open configuration - valve is open when de-energized
• 24VAC electric actuator with PopTop design for easy replacement
• 1.0 Cv flow coefficient for proper hydronic system sizing
• Brass body construction with stainless steel trim for durability and corrosion resistance
• Suitable for both horizontal and vertical pipe mounting
• Manual operating lever allows for system flushing and testing

This zone valve is engineered for on/off control of water flow in hydronic systems. The PopTop actuator design allows quick and easy actuator replacement without draining the system or removing the valve body from the piping. Designed for closed-loop applications, this valve should not be used in open systems with substantial make-up water or high dissolved oxygen levels.
