Erie By Schneider Electric VM3323T33A000 NPT Modulating Zone Valve Assembly HVAC Control Valves & Actuators - 3/4 3-Way

The Erie By Schneider Electric VM3323T33A000 is a complete zone valve assembly designed for precise flow control in HVAC hydronic heating and cooling systems. This PopTop-style valve combines a 3/4" NPT brass valve body with a 24VAC floating point actuator for reliable, modulating control of water flow in residential and commercial applications.

Key Features:

• 3-way mixing valve configuration for versatile hydronic system control
• 3/4" NPT threaded connections for easy installation
• Brass construction for durability and corrosion resistance
• 4.0 CV flow coefficient for optimal water flow capacity
• 35 PSI maximum working pressure rating
• 24VAC floating point control with non-spring return (NSR) operation
• Modulating actuator provides proportional control for precise temperature regulation
• NEMA 1 enclosure rating for general indoor use
• No lead wires included - field wiring required

This valve assembly is ideal for applications requiring proportional flow control, such as mixing hot and cold water in radiant floor heating systems, fan coil units, and zoned hydronic distribution systems. The floating point control allows the actuator to respond to control signals from compatible thermostats or building automation systems, modulating the valve position to maintain precise temperature setpoints.
