Belimo B308 Valve

The Belimo B308 Valve is a robust 1/2" NPT 3-way ball valve engineered for precise hydronic control in commercial HVACR systems. Featuring a 0.46 Cv, this valve is ideal for mixing or diverting applications, ensuring optimal flow management for heating and cooling coils. Its A-port delivers an equal percentage flow characteristic, while the B-port is modified for constant common port flow, providing reliable performance across various load conditions. Constructed with a nickel plated forged brass body and a stainless steel ball and stem, the B308 is built to withstand demanding environments. It handles chilled or hot water, including solutions with up to 60% glycol, within a temperature range of 0°F to 250°F. This HVAC control valve offers a 200 psi close-off pressure and a 600 psi body pressure rating, making it a dependable choice for critical installations. Its maintenance-free design and compatibility with various Belimo actuators simplify integration and long-term operation.

Common Questions:

What is the flow characteristic of a Belimo B308 valve?
The A-port provides an equal percentage flow characteristic, while the B-port is modified for constant common port flow, typically 70% of the A-AB flow.

How to install a Belimo 1/2 inch 3-way valve?
Installation involves threading the 1/2" NPT connections into your piping system and mounting a compatible Belimo actuator. Ensure proper orientation for mixing or diverting as required by the application. Always refer to the actuator's specific installation instructions for wiring and setup.

What applications are suitable for a B308 Belimo valve?
This valve is commonly used in air handling units for heating or cooling coils, fan coil units, unit ventilators, VAV box re-heat coils, and bypass loops. It is suitable for hydronic systems with either variable or constant flow, but it is not designed for use as a change-over valve.
