Erie By Schneider Electric VM3327P13A000 3/4" NPT 3-Way Modulating Zone Valve 35 PSI 24V Proportional Spring Return

The Erie By Schneider Electric VM3327P13A000 is a 3/4-inch NPT threaded 3-way modulating zone valve assembly designed for closed hydronic heating and cooling systems. This proportional spring return valve provides precise flow control in fan coil units, VAV reheat, unit ventilators, air handlers, and radiant applications.

Key Features:

• 3/4" NPT threaded connections for easy installation
• 3-way mixing valve configuration with 4 Cv flow coefficient
• 35 PSI maximum close-off differential pressure
• 24V AC proportional control with 0-10 VDC or 4-20 mA signal compatibility
• Spring return operation for fail-safe performance (normally closed)
• PopTop design allows actuator to snap on/off without tools or calibration
• Forged brass valve body with nickel-plated stem and brass seat
• Operating temperature range: 32°F to 200°F fluid (not steam rated)
• 400 PSI static pressure rating
• Manual override capability for manual positioning

The proportional (P-series) actuator provides direct-acting control, opening port B with increasing signal strength. The equal percentage flow characteristic ensures precise modulation for optimal system performance. Designed for closed hydronic heating and cooling systems, this valve assembly is UL Listed and suitable for NEMA Type 1 locations.
