The IMI NH Bellows-Sealed Globe Valve is engineered for nuclear power plants and critical industrial applications, offering zero-leakage performance. Designed for long service life, it operates at up to ANSI Class 2500 and is available in ¼" to 4" nominal bore sizes. The multi-ply Inconel 625 bellows ensures durability, while helium leak testing guarantees a leak rate below 1 x 10⁻⁶. With threaded, flanged, or welded connections, it offers flexibility for installation. Manual, pneumatic, or electric actuation provides versatile control, making it an ideal solution for high-pressure, high-temperature applications in nuclear and industrial environments.
