Belimo B349 Characterized Control Valve NPT Cv Stainless Steel Trim - 3-Way 2 Inch 46

The Belimo B349 is a 3-way characterized control valve (CCV) designed for precise flow control in commercial and industrial HVAC hydronic systems. This valve body features a 2-inch NPT connection with a flow coefficient (Cv) rating of 46, capable of handling 92 GPM at 4 psi differential pressure.

Construction and Materials:

• Nickel-plated forged brass body for exceptional durability and corrosion resistance
• Stainless steel ball and stem for extended service life
• A-port equal percentage flow characteristic for precise control
• B-port modified for constant common port flow
• Maximum working pressure: 400 PSI

Applications and Performance:

• Ideal for chilled or hot water applications up to 250°F maximum temperature
• Compatible with glycol solutions up to 60% concentration
• Perfect for air handling units, fan coil units, VAV box reheat coils, and bypass loops
• Characterized disc design prevents control loop hunting and optimizes energy efficiency
• Comparable Cv values to globe valves of the same size with reduced need for pipe reductions

Note: Actuator sold separately. This is the valve body only. Belimo offers compatible electric actuators for spring return or non-spring return operation to complete the assembly.
