The IMI Thompson Valves E77K Series is a bellows-sealed globe valve with pneumatic actuation, designed for nuclear power, aerospace, and hazardous fluid applications. Operating at up to 210 bar (3045 psi) and 300°C (572°F), it ensures positive shut-off with a non-rotating valve disc. A secondary gland packing enhances leak-tight performance, while the forged stainless steel body provides durability. The E77K Series meets ASME B&PV Section III standards and supports air-to-open and air-to-close actuation. It is available in threaded, butt weld, socket weld, and stub pipe connections for instrumentation and process control in nuclear and industrial sectors.
