MV Triple Eccentric Metal Seated Cryogenic Valves
IMI Orton’s MV Series valves are renowned globally for their exceptional combination of control, reliability, and compact design. Engineered for critical high-pressure, tight shut-off, high-temperature, or cryogenic applications, these valves are ideal for throttling and isolation duties in demanding environments. The unique triple eccentric design ensures enhanced performance by eliminating wear and leakage, resulting in a longer service life and reduced maintenance needs.
- Triple eccentric design: Prevents wear and leakage, extending service life.
- Resilient metal-to-metal sealing: Ensures robust, tight shut-off performance.
- Quarter-turn, friction-free operation: Minimises operational torque and energy use.
- Fire-safe and fire tested: Compliant with industry safety standards.
- Torque-seated for reliability: Ensures tight shut-off even at high pressures.
- External anti-blowout device: Provides an additional safety feature.
- Bi-directional tight shut-off: Offers sealing in both flow directions.
- Wide range of materials and sizes: Customisable to meet diverse application needs, from -254°C to +426°C.
