Belimo B330 Valve

The Belimo B330 is a high-performance 1 1/4 inch 3-way characterized control valve engineered for precise modulation in hydronic systems. Featuring a 19 Cv rating and NPT female pipe ends, this valve utilizes an A-port with an equal percentage flow characteristic and a modified B-port to ensure consistent common port flow. The construction consists of a nickel-plated forged brass body paired with a 304 stainless steel ball and stem, making it suitable for both chilled and hot water applications up to 250°F. Designed to handle up to 60% glycol solutions, the B330 provides reliable mixing or diverting functionality. The blow-out proof stem and TEFZEL characterized disc maintain high close-off pressures while preventing flow surges, ensuring stability in AHU and terminal unit configurations. This Belimo CCV is the standard for contractors requiring durable, maintenance-free flow control in demanding HVAC mechanical systems.

• Stainless Steel Trim: Standard 304 stainless steel ball and stem prevent corrosion and premature seal failure.
• Precise Flow Control: A-port equal percentage insert eliminates hunting and stabilizes temperature loops.
• Zero Leakage: Rated for bubble-tight shut-off on the A-port to maximize energy efficiency.
• High Temperature Range: Rated for media temperatures from 0°F to 250°F, covering diverse boiler and chiller setpoints.
• Universal Compatibility: Works seamlessly with Belimo LR, AR, and NR series actuators for flexible torque options.

Is the Belimo B330 suitable for steam applications?
No, this ball valve is specifically designed for water and glycol solutions up to 60%. For steam applications, a globe valve or high-temperature rated butterfly valve is required.

Can this valve be used for both mixing and diverting?
Yes, the B330 is designed for versatile piping configurations, allowing it to function as a mixing or diverting valve depending on the actuator orientation and piping layout.

What is the maximum close-off pressure for this 1 1/4" model?
The B330 typically supports a close-off pressure of 200 psi, ensuring positive shut-off and preventing bypass leakage in high-head pressure systems.
