The Belimo G250B-N bronze globe valve provides precise 2-way flow control for commercial HVAC hydronic systems using chilled water, hot water, low-pressure steam, or glycol solutions up to 60%.

Designed with a 2" internal threaded NPT connection and 40 Cv flow coefficient, this ANSI Class 250 valve supports reliable modulation for heating and cooling applications where stable water flow and accurate temperature control are required.

Its modified equal percentage flow characteristic helps improve control response, while the bronze body, bronze trim, brass plug, stainless steel stem, and EPDM O-ring stem packing deliver durable performance in demanding mechanical systems.

With stem-up-to-open operation from A to AB and pressure capability up to 400 psi for water below 150°F, the G250B-N is a dependable choice for Belimo actuator-compatible globe valve installations requiring long service life, consistent shutoff, and efficient HVAC system operation.
