EH & EHA

Fisher EH series valves are specially designed for high-pressure applications and incorporate proven techniques in flow-stream contouring for higher capacities and in valve trim design for reliability in severe applications.

EH
Features

  • Rugged cage guiding provides increased valve plug stability, which reduces vibration and mechanical noise.
  • EH and EHA valves with buttwelding end connections have Intermediate Standard Ratings. With nondestructive testing, these valves can conform to ASME Intermediate Special Ratings, which allow even higher pressure/temperature applications.
  • 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.
  • Hardened materials of construction for the cage, valve plug, cage guiding, and other trim parts are standard for all applications, providing excellent wear resistance.
  • Maintenance is simple and can easily be performed using common tools. Micro-Flute and Micro-Form valve plugs provide superb rangeability in high-pressure, low-flow applications, while maintaining tight shutoff.
