Product Bulletin Fisherr HP Series Control Valves HP (Globe Valve) HPA (Angle Valve) Balanced High-Temperature Trim Balanced Tight Shutoff Trim Unbalanced Trim 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. HP Series valves are designed with corrosion allowance; NACE compliant materials are available. Extra valve body wall thickness provides a safety margin of protection against erosion, as well as extra protection against corrosion due to chemical attack. Because these valves feature a thicker valve body wall, they are available in higher intermediate ratings with weld-end fittings. FISHER HP VALVE WITH 667 ACTUATOR AND FIELDVUE™ DVC6200 DIGITAL VALVE CONTROLLER Unless otherwise noted, all NACE references are to NACE MR0175-2002 and MR0103. Balanced Tight Shutoff Trim Balanced High-Temperature Trim HPD and HPAD These valves use a balanced valve plug with graphite piston rings and are well suited for general applications with process temperatures in excess of 232_C (450_F), where extremely tight shutoff is not required. These valves use a balanced valve plug and offer excellent shutoff with process temperatures below 232_C (450_F). The temperature limits of HPT can be extended above 232_C (450_F) to 316_C (600_F) by using PEEK (PolyEtherEtherKetone) anti-extrusion rings in combination with a spring-loaded PTFE seal. The PEEK anti-extrusion rings expand to help close off the clearance gaps on the plug outside diameter and the cage inside diameter where the PTFE seal may extrude at high temperatures and pressures.

Fisher HPD Valve Assembly (NPS 2 to 6) Cavitrol III, Whisper Trim III, and WhisperFlo Cages To eliminate cavitation damage in a properly-sized valve, a Cavitrol III cage is available with HPS, HPAS, HPT, and HPAT control valves. To help attenuate aerodynamic noise in gaseous service, Whisper Trim III and WhisperFlo (figure 2) cages are available with HPD, HPAD, HPS, HPAS, HPT, and HPAT control valves. Contact your Emerson Process Management sales office for more information. Valve Plug Stability– Rugged cage guiding provides increased valve plug stability, which reduces...

Product Bulletin Standard Hard Trim Materials–The cage, valve plug, and other trim parts are manufactured from hardened materials. This standard feature provides excellent wear resistance. Control of Low Flow Rates/Tight Shutoff–Micro-Flute and Micro-Form valve plugs (figures 6 and 7, respectively) provide superb rangeability in high-pressure, low-flow applications, while maintaining tight shutoff (table 4). 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....

Product Bulletin Material Selection Guidelines from tables 7 and 12. Refer to figure 12 to determine pressure drop limits of the valve body-trim combinations selected. Use the following steps as a guideline for the selection of materials: 1. Determine the pressure/temperature rating of the valve body size and material required. Inlet pressure and temperature must always be limited by the applicable ASME pressure/temperature rating. 2. Select the desired trim style from the Available Configurations specification and from table 4, Shutoff Classifications. 3. Select desired materials from tables...
