Erie By Schneider Electric VM3313P13A000 3/4" Sweat 3-Way Proportional Zone Valve 24V Normally Closed

The Erie By Schneider Electric VM3313P13A000 is a three-way modulating zone valve assembly designed for hydronic heating and cooling systems. This complete assembly features a 3/4-inch sweat connection valve body paired with a proportional spring return actuator, providing precise control over water flow in residential and light commercial HVAC applications.

Key Features:

• 3/4-inch sweat (copper) connections for easy soldering installation
• Three-way mixing or diverting configuration for versatile system design
• Proportional control actuator (AP13A000) with 0-10 VDC or 4-20mA input signal
• Spring return normally closed operation for fail-safe performance
• 24 VAC power supply with low energy consumption
• 35 PSI maximum differential pressure rating
• 4 Cv flow coefficient for balanced system performance
• Forged brass body construction for durability and corrosion resistance
• PopTop replaceable actuator design for easy maintenance and field service

Technical Specifications:

• Connection Type: 3/4" sweat (copper tube)
• Configuration: 3-way zone valve
• Actuator Type: Proportional, spring return
• Control Signal: 0-10 VDC or 4-20 mA DC
• Voltage: 24 VAC @ 50/60 Hz
• Normal Position: Closed (B port closed, A port open when de-energized)
• Maximum Differential Pressure: 35 PSI
• Flow Coefficient (Cv): 4
• Operating Temperature: 32°F to 250°F fluid temperature

The proportional actuator allows for modulating control based on system demand, making this valve ideal for applications requiring precise temperature control through mixing or diverting water flow. The spring return feature ensures the valve returns to its normally closed position during power loss, providing inherent system safety. The Erie PopTop design allows the actuator to be replaced without removing the valve body from the piping system, reducing service time and costs.

This valve assembly is suitable for use in closed-loop hydronic systems including radiant heating, hydronic baseboards, fan coils, and other zone control applications where three-way modulating control is required.
