Description
The Belimo B307B is a precision-engineered 3-way ball valve designed for reliable flow control in chilled and hot water HVAC applications. Built to withstand demanding hydronic system conditions, this valve features a durable nickel-plated forged brass body paired with a chrome-plated brass ball and nickel-plated brass stem for exceptional corrosion resistance and long service life.
Flow Characteristics
The B307B utilizes a dual-port flow design engineered for balanced system performance:
- A-port: Equal percentage flow characteristic for precise, proportional control across the full stroke range
- B-port: Modified flow characteristic designed to maintain constant common port flow, ensuring stable system pressure and consistent performance
