Belimo B307B Valve
The Belimo B307B is a professional-grade 1/2 inch 3-way ball valve designed for precise flow control in demanding hydronic systems. Featuring a 0.3 Cv rating, this valve utilizes an A-port equal percentage flow characteristic and a modified B-port for constant common port flow, ensuring stable heat transfer across varying loads. The housing is constructed from nickel-plated forged brass, paired with a chrome-plated brass ball and nickel-plated stem to handle chilled or hot water up to 250°F and glycol solutions up to 60%. This NPT-threaded unit is ideal for VAV reheat coils, fan coil units, and unit ventilators where tight shut-off and high close-off pressure ratings are required.
Key Benefits for Technicians:
- Optimized Flow Control: The specialized characterization disc ensures linear heat output, preventing hunting and improving overall system efficiency.
- High Temperature Resilience: Rated for temperatures up to 250°F, making it a versatile choice for both heating and cooling loops.
- Durable Construction: The nickel-plated brass body and chrome-plated ball provide excellent resistance to scaling and corrosion.
- Zero Leakage: Engineered for bubble-tight shut-off, reducing energy waste and preventing unintended flow in mixed systems.
- Low Torque Design: Allows for the use of smaller, more cost-effective actuators while maintaining reliable operation.
Common Questions:
What actuators are compatible with the B307B?
This valve is designed to pair with Belimo LR, AR, and KR series non-spring return and spring return actuators, facilitating easy field installation or retrofitting.
Can this valve be used in steam applications?
No, the B307B is rated strictly for water and glycol solutions up to 60%; it is not suitable for steam service due to seal and seat material limitations.
Which port should be used for the bypass?
In a typical mixing or diverting setup, the B-port is the bypass and is internally modified to provide consistent flow to the common port, simplifying system balancing.
