E74D & E74H Type 174 Mk2 - Bellows Sealed Globe Valve
Bellows-sealed globe valve for high-pressure and nuclear applications.
Bellows-sealed design ensures zero leakage and pressure containment.
Handles extreme pressures and hazardous fluids in critical applications.
Replaceable valve disc extends operational life.
The IMI Thompson Valves E74D/E74H 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 provides additional sealing for pressure containment. Constructed from forged stainless steel, it meets ASME B&PV Section III standards. Available in threaded, butt weld, socket weld, and stub pipe connections, the E74D/E74H Series is ideal for instrumentation and process control in nuclear, marine, and defence sectors.
