• Flow coefficient (Cv): 2.2
• Valve configuration: 3-way mixing valve with linear flow characteristic
• Bronze body with bronze plug and seat
• Stainless steel stem with spring-loaded TFE packing
• Pneumatic actuation with 5-10 PSI spring range
• Close-off pressure: 150 PSI
• Media temperature range: 20°F to 281°F (-7°C to 138°C)
• Maximum working pressure: 200 PSI at 20°F to 150°F

Applications and Features:

Part of Schneider Electric's VB-7000 Series, this valve assembly is engineered for demanding HVAC control applications. The bronze construction provides excellent durability for hot and chilled water systems, while also supporting steam applications up to 35 PSIG. The valve is compatible with glycol solutions up to 50% concentration, making it suitable for freeze protection systems.

The pneumatic actuator operates on a 5-10 PSI spring range, providing responsive control without requiring a positioner for most applications. The valve body uses brass trim with soft seats to ensure tight shutoff and long service life. The compact design allows for installation in space-constrained mechanical rooms and equipment closets.
