E78D & E78H - Forged Bellows Sealed Globe Valve
Bellows-sealed globe valve for high-pressure and nuclear applications.
Bellows-sealed design prevents leaks and ensures pressure containment.
Handles hazardous fluids under high pressure and extreme temperatures.
Secondary gland packing enhances sealing reliability.
Features
The IMI Thompson Valves E78D/E78H Series is a bellows-sealed globe valve designed for nuclear power, aerospace, and hazardous fluid applications. Operating at up to 414 bar (6003 psi) and 350°C (662°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 ensures durability. The valve meets ASME B&PV Section III standards and is available in threaded, butt weld, socket weld, and stub pipe connections. Ideal for high-pressure instrumentation and process control, the E78D/E78H Series is suited for nuclear, marine, and defence industries.
