Fisher easy-e EW Universal Globe Valves – Sliding Stem Valves

Fisher easy-e EW Universal Globe Valves are part of the sliding stem valve range that have either balanced or unbalanced plugs, cage-guided trim, and feature large internal cavities with expanded end connections for all general applications with process temperatures up to 593°C (1100°F).

The easy-e EW valves are available in sizes ranging from NPS 4×2 to 24×20 where size designations are end connection size x nominal trim size. All sizes are available in pressure ratings up to CL600, with the NPS 8×6 and 12×8 sizes also available in CL900 ratings. Several globe body, sliding-stem configurations are available, including EWD, EWS, and EWT:

EWD: Balanced push-down-to-close valve for applications with process temperatures up to 593°C (1100°F)
EWS: Unbalanced push-down-to-close valve for applications with process temperatures up to 566°C (1050°F)
EWT: Balanced push-down-to-close valve for applications with process temperatures up to 316°C (600°F)

Fisher easy-e EW 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
Piping Economy–Expanded end connections of EW series valve bodies may reduce the need for line swages, while accommodating oversized piping arrangements used to limit fluid flow velocities
Increased Pressure/Temperature Ratings–NPS 12×8 CL900 EW series valve bodies with buttwelding end connections are capable of increased ASME ratings, called Intermediate Standard Ratings. The extra strength of the valve body allows these valves to be used where pressures and temperatures exceed Standard Class ratings in ASME B16.34
Valve Plug Stability— Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise
Balanced Valve Plug Construction— EWD and EWT 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 4×2 to 12×8 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

1. The pressure/temperature limits in this bulletin and any applicable standard or code limitation should not be exceeded. 2. Certain bonnet bolting material selections may require a CL600 easy-e valve assembly to be derated. Please contact. 3. Only NPS 12×8 CL900 valve bodies with threaded (-1) seat rings can take full CL900 pressure drops; CL900 valve bodies with clamped (no dash number) seat rings are limited to CL600 pressure drops. Also, there are two different NPS 8×6 CL900 valve bodies, one for use only with Cavitrol III cages and the other for use with all other constructions. An NPS 8×6 CL900 valve body with Cavitrol III cage can take full CL900 pressure drops. For information on other NPS 8×6 constructions that can take full CL900 pressure drops, please contact All other NPS 8×6 constructions are limited to CL600 pressure drops (1440 psid flowing drop) even though installed in a CL900 valve body. 4. Restriction based on excessive noise if max P/P1 ratio for a given cage level is exceeded. 5. Down:in through cage and out through seat ring (direction shown in figure 1 see data sheet). 6. Up:in through seat ring and out through cage as shown in figure 13 see data sheet
