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.
See how Fisher Control Valves provide safe, efficient and intuitive flow control.
