Fisher HP & EH High Pressure Globe Valves – Sliding Stem Valves
Fisher HP & EH High Pressure Globe Valves – Sliding Stem Valves
Fisher HP & EH High Pressure Globe Valves are part of the sliding stem valve range for high-pressure steam, hydrocarbon, or general service, including cavitating liquids or noisy gases and vapours. The Fisher HP & EH are suitable for temperatures to 537ºC and pressures to PN160 (CL2500) and sizes from DN25 through DN100 DIN and NPS 1 through 20.
HP & EH valves have ENVIRO-SEAL™ and HIGH-SEAL packing systems to help ensure compliance with environmental emissions requirements. FIELDVUE™ digital valve controllers.
Fisher HP & EH High Pressure Globe Valve
Product Features
- Valve Plug Stability— Rugged cage guiding provides increased valve plug stability, which reduces vibration and mechanical noise.
- Full Pressure Drop Capability—Rugged HP and HPA valves have readily available trims capable of attaining full pressure drops.
- 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.
- Compliance with the Clean Air Act—Optional ENVIRO-SEAL™ packing systems provide an improved stem seal to help prevent the loss of valuable process fluid or emission of hazardous process fluid. The ENVIRO-SEAL packing systems feature PTFE or graphite ULF.
- Piping Economy—The availability of expanded end connections on NPS 4 and 6 HP 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.
- 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 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
