IMI CCI
MGK - Pilot Operated Isolation Valve
A robust pilot-operated valve for controlling high-flow main valves in nuclear and industrial applications.
Provides precise, high-flow control for main steam and feedwater isolation valves in nuclear applications.
Forged carbon or stainless steel construction ensures long-term durability in extreme operating conditions.
Fully compliant with IEEE 323, IEEE 344, and RCC-E standards for reliable nuclear safety performance.
Features
The MGK Pilot Operated Valve is designed for precise control of high-flow main valves in nuclear power plants and industrial applications. Used as a main steam isolation valve in BWR and PWR systems, it also functions in feedwater and bypass isolation. The MGK integrates IMI CCI’s IEEE-qualified positioning system and offers robust operation with air, steam, water, and acids. Available in 1” (25mm) and 2” (50mm) sizes, it is built from forged carbon or stainless steel for durability. Equipped with dual pilot valve connections, it ensures reliable activation and smooth performance in demanding environments.
