Belimo G250S-N Valve

For high-performance flow regulation in demanded HVAC and steam systems, the Belimo G250S-N Globe Valve delivers reliable 2-way control with a 40 Cv rating. This 2-inch NPT globe valve is engineered with a robust bronze body and 316 stainless steel trim, ensuring structural integrity in chilled water, hot water, and low-pressure steam applications. Featuring a modified equal percentage flow characteristic, the G250S-N provides precise linear modulation for air handling units, heating coils, and bypass loops. The "stem up to open" design combined with a 100:1 rangeability allows for superior throttling accuracy at low flow rates. Rated for ANSI Class 250, this valve manages media temperatures up to 338°F and differential pressures up to 50 psi for steam. Contractors trust this 2-way valve for its ANSI Class VI leakage rating, which ensures tight close-off and maximizes plant efficiency by preventing energy loss in variable flow hydronic systems.

• Precise Modulation: The modified equal percentage characteristic provides accurate control over the full range of the 40 Cv capacity.
• Superior Durability: Equipped with a 316 stainless steel seat, plug, and stem to resist corrosion and wear in high-temperature steam service.
• High Close-Off Reliability: Achieves an ANSI Class VI leakage rating, providing air-tight shutoff to maintain system pressure and comfort levels.
• Versatile Application: Suitable for hydronic fluids (up to 60% glycol) and steam, making it a standard choice for commercial HVAC control valves.
• Actuator Compatibility: Designed for seamless integration with Belimo LVB, NF, and LVKB series actuators for various failsafe requirements.

What is the maximum pressure rating for the Belimo G250S-N?
This valve is an ANSI Class 250 component, capable of handling body pressures up to 400 psi at temperatures below 150°F, and is rated for a maximum inlet steam pressure of 100 psi.

Can this globe valve be used for steam applications?
Yes, the stainless steel trim and bronze body are specifically rated for both chilled/hot water and steam applications, supporting media temperatures from 20°F up to 338°F.

What is the flow direction for the G250S-N?
The valve features a 2-way flow pattern where the "stem up" position opens the flow from port A to AB. Installers must follow the flow arrow on the valve body to prevent seat damage.
