E73D & E73H Type 174 Mk1 - Bellows Sealed, Actuated, Globe / Needle Valve
Bellows-sealed globe/needle valve for high-pressure applications.
Bellows-sealed design prevents leaks and ensures containment.
Handles hazardous fluids under extreme pressures and temperatures.
Replaceable valve disc for extended service life
The IMI Thompson Valves E73D/E73H Series is a manually actuated, bellows-sealed globe/needle valve designed for nuclear power, aerospace, and hazardous fluid applications. It operates at up to 210 bar (3045 psi) and 300°C (572°F), ensuring positive shut-off with a non-rotating valve disc. A secondary gland packing provides an additional seal for enhanced containment. Built from forged 316L stainless steel or carbon steel, it meets ASME B&PV Section III requirements. With threaded, butt weld, socket weld, and stub pipe options, the E73D/E73H Series is ideal for instrumentation and process control in demanding industries.
