Description
Belimo B347 2" B3 Series 3-Way Characterized Control Brass Valve with Stainless Steel Ball & Stem (29.0 Cv)
Belimo’s B347 Characterized Control Valve (CCV) provides precise, stable control with an equal percentage flow characteristic, similar to a globe valve, overcoming the typical S-shaped flow curve of conventional ball valves. This is achieved by a special characterizing disc inside the valve that controls the flow increase as the valve opens, ensuring smooth part-load behavior and optimized energy consumption.
This valve is ideal for hydronic systems with variable flow, offering improved stability and energy efficiency compared to standard ball valves.
Suitable Return Actuators:
-
AR Series (Non-Spring)
-
AR...N4 Series (Spring)
-
AF Series (Spring)
