Product Overview

Fisher easy-e ET Universal Globe Valvesare part of the sliding stem valve rangethat have balanced plugs and cage-guided trim for all general applications with process temperatures up to 316°C (600°F).

The easy-e ET valves are available in sizes ranging from NPS 1 to 30 and pressure ratings up to CL600, with several different body configurations, including ET, EAT, and ETR:

  • ET: Globe body sliding-stem valve with push-down-to-close action
  • EAT: Angle body sliding-stem valve with push-down-to-close action
  • ETR: Globe body sliding-stem valve with push-down-to-open action

Fisher easy-e ET product range is available for a wide range of applications, including sulphide and chloride stress-cracking environments common to the oil and gas production industries.

Product Features

  • Compliance with the Clean Air Act—ENVIRO-SEAL™ packing systems provide an improved stem seal to help prevent the loss of process fluid. The ENVIRO-SEAL packing systems feature PTFE, Graphite ULF, or Duplex packing with live loading for reduced packing maintenance
  • Valve Plug Stability— Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise
  • Balanced Valve Plug Construction— Balanced valve plugs permit the use of smaller, lower-cost Fisher actuators
  • More Flow Capacity for Initial Investment— Streamlined flow passages provide excellent capacities and flow
  • Compliance with European Standards— NPS 1 to 8 valves are available with dimensions specified by EN/DIN standards
  • Sour Service Capability—Materials are available to meet NACE standards
  • Operating Economy—Increased wear resistance provided by standard, hardened stainless steel trim means long service life
  • Maintenance Economy— Trim inventory costs are cut because dimensional standardization permits use of most standard easy-e trim parts. During removal of trim parts, the valve body can stay in the pipeline. The EDR valve also features easy valve access without removing the actuator

PRODUCT Specification

1. EN (or other) ratings and end connections can usually be supplied. Please contact 2. The pressure or temperature limits in this bulletin, and any applicable code limitations, should not be exceeded. 3. Certain bonnet bolting material selections may require a CL600 easy-e valve assembly to be derated. Please contact 4. Limitation based on excessive noise increase if max ΔP/P1 ratio for a given cage level is exceeded.
