Fisher™ HP Series Control Valves

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.

• 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 accommodatingoversized 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 extrastrength 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.
