The IMI NH 3-piece 2-way ball valve is designed for severe service applications in nuclear power plants, providing reliable isolation and long service life. It operates in high-radiation environments, ensuring leak-tight shutoff with a floating ball design. Available in ½” to 8” sizes with ANSI ratings from 150 to 1500, it features carbon or stainless steel bodies, manual, pneumatic, or electric actuation, and various end connections. The N and NPT stamped design meets ASME qualifications, while radiation-resistant seats lower torque and improve sealing performance. The 3-piece design allows easy maintenance without valve removal.
