Produktbeschreibung

Fisher HP series control valves are single-port, high-pressure, globe- or angle-style valves with metal seats, cage guides, and push-down-to-close valve plug action. These valves are designed for high-pressure applications in process control industries such as power generation, hydrocarbon production, chemical processing, and refining.

Merkmale

  • Valve Plug Stability – Rugged cage guiding provides increased valve plug stability, which reduces vibration and mechanical noise.
  • Full Pressure Drop Capability – Rugged construction allows full pressure drop capability in HP series valves.
  • Spiral-Wound Gaskets for Excellent Sealing Under All Service Conditions – Premium materials are used in the construction of spiral-wound gaskets for HP Series valves. These premium materials, which make up the standard spiral-wound gaskets, are N06600 (alloy 600)/graphite or N07750 (alloy X750)/graphite.
  • Piping Economy – The availability of expanded end connections on NPS 4 and 6 HP (ISA 75.08.05 (long) or ISA 75.08.06 (long)) valves may eliminate the need for line swages while accommodating oversized piping arrangements.
  • Quick Change Trim – Maintenance is simple and can easily be performed using common tools. Trim components can be quickly removed and changed with no need for special tools.
  • Integrated Cage-Seat Ring Design – Find this option on globe NPS 8, 10, 12, 14 and angle NPS 12 valves offering easier maintenance and better shutoff.
  • Standard Hard Trim Materials – The cage, valve plug, and other trim parts are manufactured from hardened materials. This standard feature provides excellent wear resistance.
  • Increased Pressure/Temperature Ratings – HP Series valves with weld-end fittings have increased pressure/temperature ratings, called intermediate ratings, as defined in ASME B16.34. The extra strength of these valves allows ratings higher than the standard CL900 or 1500 ratings specified in B16.34. The globe NPS 8 to 12 HP is available as a standard Intermediate ANSI Class 3200 to achieve higher pressure/temperature ratings. Not available on angle NPS 8. Contact your Emerson sales office for further information on intermediate ratings.
  • Trim Interchangeability – Cavitrol III, Whisper Trim III, and WhisperFlo trims are interchangeable with standard trims.
  • Control of Low Flow Rates/Tight Shutoff – Micro-Flute and Micro-Form valve plugs provide superb rangeability in high-pressure, low-flow applications, while maintaining tight shutoff. A choice of several restricted port diameters helps to match valve body capacity to required flow, to provide necessary control with full travel, and to prevent throttling near the seat. In low-flow applications where cavitation damage may occur, the Micro-Flat valve plug can be used with a special Cavitrol III cage. Contact your Emerson sales office for more information.
  • Smooth Control at High Pressure Drops – Available on NPS 2 through 14 valves, balanced trim provides smooth control at high pressure drops.
