Belimo B207 Valve

The Belimo B207 is a precision-engineered 1/2 inch NPT 2-way characterized control valve designed for demanding hydronic HVAC applications. Featuring a 0.3 Cv rating, this valve utilizes a specialized equal percentage flow characteristic to ensure linear heat output from coils, providing superior temperature stability in chilled or hot water systems. The construction consists of a rugged nickel-plated forged brass body paired with a stainless steel ball and stem, offering high chemical resistance and durability in systems with up to 60% glycol solution. Rated for fluid temperatures up to 212 F, the B207 integrates a Tefzel flow-characterizing disc to prevent hunting and pressure surges. This HVAC control valve is a standard for professional contractors seeking reliable modulating ball valve performance with high close-off pressure ratings and zero leakage, ensuring peak efficiency in building automation workflows.

• Equal Percentage Flow: Provides predictable control and prevents system hunting by normalizing heat exchanger output.
• Corrosion Resistance: The 304 stainless steel ball and stem assembly prevent pitting and scale buildup in harsh water conditions.
• High Glycol Compatibility: Safely handles concentrations up to 60% for effective freeze protection in hydronic loops.
• Leak-Free Performance: Engineered for zero percent leakage, reducing energy waste and maintaining system pressure integrity.
• Universal Compatibility: Designed for seamless integration with Belimo LR and TR series actuators for precise automation.

What is the maximum pressure rating for the Belimo B207?
The B207 features a body pressure rating of 600 psi, though actual close-off pressure is determined by the specific actuator paired with the valve assembly.

Can this valve be used in steam applications?
No, the B207 is specifically rated for chilled and hot water systems up to 212 F; steam applications require specialized high-temperature valve bodies.

Does the 0.3 Cv rating affect the installation orientation?
While the equal percentage flow disc ensures performance, the valve must be installed with the flow in the direction of the arrow on the valve body to maintain control accuracy.
