Schneider Electric VK4-7313-202-4-9 1-1/4" 3-Way Globe Valve Assembly with Pneumatic Actuator

The Schneider Electric VK4-7313-202-4-9 is a pre-assembled 1-1/4 inch three-way mixing globe valve with integrated pneumatic actuator and positive positioner. This valve assembly is designed for precise proportional control of chilled water, hot water, or steam in commercial HVAC systems.

Key Features:

• 1-1/4 inch NPT threaded bronze body construction for durability
• Three-way mixing configuration with stem down flow pattern
• Brass trim components for corrosion resistance
• Flow coefficient (Cv) of 20 for efficient water flow
• Pre-assembled with Barber Colman MK-2690 pneumatic actuator
• 5-10 PSI control spring range for proportional control
• Integrated positive positioner for accurate valve positioning
• Rugged die-cast aluminum actuator housing with replaceable neoprene diaphragm
• 6 square inch effective diaphragm area

This factory-assembled valve and actuator combination is part of the VB-7000 series, eliminating field assembly requirements and ensuring proper installation. The pneumatic actuator provides reliable, proportional control in response to pneumatic control signals from building automation systems. Compatible with standard pneumatic controls for precise temperature and flow regulation in heating, cooling, and hydronic applications.
