Schneider Electric VS-7323-593-4-9 1-1/4" 3-Way Diverting Globe Valve Assembly with Proportional Actuator

The Schneider Electric VS-7323-593-4-9 is a complete actuated valve assembly that combines a 1-1/4 inch VB-7323 series bronze globe valve body with an MS51-7203 SmartX linear electric actuator. This assembly features 3-way diverting configuration, NPT threaded connections, bronze trim, 20 Cv flow coefficient, and 250 PSI maximum pressure rating.

Valve Body Features:

• VB Series valves are designed for control of chilled water, hot water, or steam in HVAC applications
• 1-1/4 inch threaded bronze body construction
• 3-way diverting configuration with one inlet and two outlets
• 20 Cv flow coefficient for precise flow control
• 250 PSI maximum working pressure
• Bronze trim for durability and corrosion resistance

MS51-7203 Actuator Specifications:

• Spring return proportional control with 220 lbf force output
• 24 VAC/VDC power supply with 2-10 VDC proportional control signal
• Integral linkage provides linear travel
• 1/2 inch (13mm) stroke length
• Weighs approximately 4.3 lbs (1.9 kg)
• NEMA 2 enclosure rating (air plenum rated)
• 3-foot plenum rated cable included
• Manual override with crank for emergency positioning

Applications:

Typical applications include reheat on VAV boxes, fan coil units, hot and chilled water coils in air handling units, unit ventilators, and central system applications. The proportional control allows for precise modulation from building automation systems or DDC controllers using 2-10 VDC control signals.

Installation Notes:

Install three-way diverting valves with one inlet and two outlets. The actuator features switch-selectable direct/reverse action for flexible installation. UL 873 and cUL certified for reliability in commercial HVAC systems.
