Belimo B263 Valve

The Belimo B263 is a 2 1/2-inch NPT characterising control valve designed for high-precision regulation in hydronic systems. Featuring a 110 Cv rating, this 2-way ball valve utilizes a specialized disc to ensure equal percentage flow characteristics, preventing hunting and improving heat exchanger efficiency. Built with a nickel-plated forged brass body and a 304 stainless steel ball and stem, the B263 is rated for temperatures up to 212°F and fluid concentrations containing up to 60% glycol. This HVAC control valve is a standard choice for chilled or hot water applications, offering a 0% leakage rate at 50 psi. Its blowout-proof stem design and high close-off pressure ratings make it a reliable component for large-scale air handling units and central plant upgrades. Contractors value the standard NPT threading for straightforward integration into existing piping manifolds, ensuring consistent hydronic balancing and reduced pump energy consumption in commercial climate control systems.

Key Benefits for Technicians
  • Precise Flow Control: The integrated characterizing disc ensures linear heat output from the coil, even under varying system pressures.
  • Durable Construction: Stainless steel trim minimizes corrosion and prevents seizing in high-duty cycle hydronic applications.
  • Reduced Maintenance: Low torque requirements allow for use with smaller, more efficient Belimo actuators, extending the life of the drive train.
  • Chemical Resistance: Rated for up to 60% glycol solution, making it ideal for freeze-protected loops and industrial cooling towers.
Common Questions

What is the maximum close-off pressure for the B263?
When paired with the appropriate non-spring return or spring return actuator, the B263 provides a tight close-off rating of 100 psi to prevent ghost flows.

Can this valve be field-serviced?
The valve body is designed for long-term installation; however, the actuator can be easily replaced or manually overridden during system commissioning.

Is the B263 suitable for steam applications?
No, this unit is specifically engineered for chilled or hot water and glycol solutions up to 212°F. For steam applications, a different series of Belimo valves is required.
