Description
The Belimo B341 is a heavy-duty 3-way ball valve engineered for demanding chilled water and hot water HVAC applications. Featuring a nickel-plated forged brass body paired with a stainless steel ball and stem, this valve delivers exceptional corrosion resistance and long service life in both heating and cooling systems.
Key Features
- 1-1/2″ NPT connection for straightforward installation into standard piping systems
- 46 Cv flow coefficient for high-capacity flow performance
- 3-way configuration for versatile mixing or diverting applications
- A-port: Equal Percentage flow characteristic for precise, stable control across the full stroke range
- B-port: Modified flow characteristic engineered for constant common port flow, maintaining system balance
- Nickel-plated forged brass body for superior strength and corrosion resistance
- Stainless steel ball and stem for durability and reliable sealing performance
- Rated for chilled or hot water service up to 250°F maximum
Application
The B341 is ideally suited for commercial and industrial HVAC hydronic systems including fan coil units, air handling units, and terminal units requiring precise flow control. The equal percentage A-port characteristic provides excellent controllability at partial loads, while the modified B-port ensures stable common port flow — a critical requirement in variable-flow hydronic systems.
