Fisher Globe Control Valves

Fisher Globe Control Valves

Fisher Globe Control Valves are available in a variety of sizes (NPS ½ thru 36) and provide users with performance and flexibility.

They can help solve an array of application needs from big to small, hot to cold, general to severe. Fisher globe control valves have a selection of valve cages or plugs that can be interchanged to modify the inherent flow characteristic to linear, equal percentage, or quick opening to meet capacity demands from 0.0001 Cv up to 12,000 Cv. Fisher easy-e™ control valves pioneered the use of cage-guided trim.

Globe Valve

Globe Valves use a linear motion to move a closure member into and out of a seating surface. They have a body distinguished by a globular-shaped cavity around the port region. Many single-seated valve bodies use a cage or retainer-style constructions to retain the seat ring, provide valve plug guiding, and provide a means for establishing particular valve flow characteristics. Cage or retainer-style single-seated valve bodies can also be easily modified by the change of trim parts to provide reduced capacity flow, noise attenuation, or reduction or elimination of cavitation

Features

• ENVIRO-SEAL™ packing systems that provide an improved stem seal to help prevent the loss of process fluid are available. These packing systems feature PTFE or Graphite ULF packing with live-loading for reduced packing maintenance.
• Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise.
• Streamlined flow passages in the ED, EAD, and EDR valves provide excellent capacities and flow.
• The increased wear resistance of hardened stainless steel trim means longer-lasting service.
• Use of multiple graphite piston rings permits Class IV shutoff up to 593°C (1100°F). Use of C-seal trim permits Class V shutoff up to 593°C (1100°F).
• Valves are available with dimensions specified by EN/DIN standards.
• Unless otherwise noted, references are to NACE MR0175-2002. Optional materials are available to meet NACE MR0103 and NACE MR0175 / ISO 15156.
