Belimo G350B-N Valve

The Belimo G350B-N is a heavy-duty 2-inch NPT 3-way globe valve engineered for precision fluid control in demanding HVAC applications. This mixing and diverting valve features a robust bronze body and brass trim, making it ideal for managing chilled or hot water and hydronic systems with up to 60% glycol. Rated for ANSI Class 250, the G350B-N handles pressures up to 400 psi at temperatures below 150°F, with an operating range of 20°F to 280°F. With a 41 Cv rating and ANSI Class VI leakage protection, it ensures tight shut-off and high-efficiency performance. The valve utilizes a modified equal percentage flow characteristic on the A-port and a linear flow on the B-port, providing stable control for air handling units and fan coil units. Built for longevity, the stainless steel stem and EPDM O-ring seals provide reliable service in both constant and variable flow loops.

• Versatile Application: Designed for both mixing and diverting configurations in high-pressure hydronic loops.
• Superior Sealing: Achieves ANSI Class VI leakage rating, ensuring minimal energy loss through the bypass.
• High Pressure Capacity: Built to ANSI Class 250 specifications to withstand rigorous commercial environments.
• Precise Modulation: Features high rangeability (A-port 100:1) for accurate temperature maintenance in HVAC control.
• Serviceable Design: Compatible with repack kits, allowing for field maintenance without full valve replacement.

Is the Belimo G350B-N suitable for steam applications?
While primarily used for water and glycol, some regional specifications allow for low-pressure steam; however, always verify the specific medium temperature and pressure limits against the submittal sheet for your project.

Which actuators are compatible with this 2-inch globe valve?
The G350B-N is compatible with Belimo SVB(X), AFB(X), and SVKB(X) series actuators, providing options for non-spring return, spring return, or electronic fail-safe operation.

Can this valve be mounted in any orientation?
For maximum service life, the valve should be mounted with the stem upright. While horizontal mounting is permitted, the actuator must never be positioned below the valve body to prevent damage from condensation.
