Fisherr EW Series (EWD/EWS/EWT) Sliding-Stem Control Valves through NPS 12x8

Fisher EW Series easy-et valves (figures 1, 2, 3, and 4) feature large internal cavities with expanded end connections and a variety of unbalanced and balanced plug designs. Sizes available from NPS 4x2 12x8. These combinations provide good fluid control in economical, high-capacity valve bodies that keep valve outlet velocities within practical limits.

These valves meet a variety of service requirements, such as power plants where oversized piping is used to limit fluid flow velocity. They also perform well in noise abatement applications; for example, high-pressure gasreducingstationswheresonicvelocitiesareoften encountered at the outlet of conventional valve bodies.

The Fisher EW product line is available for a wide range of applications, including sulfide and chloride stress-cracking environments common to the oil and gas production industries. To discuss available constructions, contact your Emerson Process Management sales office and include the applicable codes and standards required for these environments.

The easy-e Valve Family

EW Series valves are part of the versatile easy-efamily of Fisher industrial control valves. easy-evalvesshare the following characteristics:

 Multiple trim material choices

 Trim temperature capability with metal seats

standard to 427_C(800_F)

 Interchangeable, restricted-capacity trims and

full-size trims to match variable process flow demands

W2777-3

 Different cage/plug styles that provide particular

flow characteristics for highly-specialized applications. The standard cage comes in three different flow characteristics:

D quick-opening D linear D equal percentage

 Cavitrolt III cages are available to eliminate

cavitation damage and Whisper Trimt III cages are available to help attenuate aerodynamic noise.

 316 stainless steel packing box parts are standard

(including packing flange, studs, and nuts)

The temperature limits of EWT valves can be extended above 232_C(450_F) by using PEEK

Features

 Compliance with the Clean Air Act– ENVIRO-SEAL™

packing systems provide an improved stem seal to help prevent the loss of valuable or hazardous process fluid. The ENVIRO-SEAL packing systems featurePTFEorGraphiteULFpackingwith 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.

 Temperature C ompensation–On designs with the

seat ring threaded into the valve body (figure 4), the hung cage feature helps reduce gasketing problems caused by thermal expansion and contraction of long parts, such as the cage assembly.

 Standard Trim Parts across the easy-e product

line–Included are FGM gaskets, packing flange, studs, and nuts.

 High-Temperature, Class IV or Class V

Shutoff–Optional multiple piston rings (figure 14) for EWD and EWD-1 valve bodies permit Class IV shutoff up to 593_C (1100_F). Use of C-seal trim for EWD (see figure 5) permits Class V shutoff up to 593_C (1100_F).

 Increased Pressure/Temperature Ratings–NPS 12x8

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.

See Bulletin 59.1:027, Increased Pressure/ Temperature Ratings for EH and EW Series Steel Valves (D100076X012), for further information.

 Noise Attenuation–In an EW Series valve, noise

produced by high flow rates and large pressure drops can be reduced by up to 18 dbA with a Whisper Trim I cage, by up to 30 dbA with a Whisper Trim III cage, and by up to 40 dbA with a WhisperFlo cage.

C-seal Trim Description

C-seal trim (figure 5) is available for valves with port diameters from 2.875 inches through 8 inches.

With C-seal trim, a balanced valve can achieve high-temperature, Class V shutoff. Because the C-seal plug seal is formed from metal (N07718 nickel alloy) rather than an elastomer, a valve equipped with the C-seal trim can be applied in processes with a fluid temperature of up to 593_C (1100_F).

ENVIRO-SEAL and HIGH-SEAL Packing Systems

Fisher ENVIRO-SEAL and HIGH-SEAL packing systems (figure 18) offer excellent sealing capabilities. These systems easily install in your existing valves or can be purchased with new valves. These systems help you seal your process to conserve valuable process fluid and to protect the environment against the emission of hazardous or polluting fluids. The long-life and reliability of these systems also reduce your maintenance cost and downtime.

For applications requiring compliance with environmental protection regulations, the unique ENVIRO-SEAL packing system and, for hazardous service, the ENVIRO-SEAL bellows seal bonnet (figure

19) are offered. The emission control packing system or seal bonnet keeps emission concentrations below the EPA 100 ppm requirement.

For an excellent stem seal in applications that are not environmentally-sensitive, the HIGH-SEAL Graphite ULF packing system is offered. The HIGH-SEAL packing system provides excellent sealing at pressure/temperature ratings beyond ENVIRO-SEAL limits.

ENVIRO-SEAL packing systems, available with PTFE, Graphite ULF, or Duplex packing, and the HIGH-SEAL Graphite ULF packing system feature live-loading and unique packing-ring arrangements for long-term, consistent sealing performance.

Material Selection Guidelines

Regardless of valve construction, select the valve body/bonnet material from the specifications table, keeping in mind that the valve service conditions cannot exceed the ASME pressure/temperature limitations for the selected valve body. Then, perform steps 1 and 2 under the appropriate valve design heading to complete the selection process.

EWD, EWS, or EWT Valve With All Except Cavitrol III or Whisper Trim III Cages

1. Choose a trim combination for the service conditions according to figure 7 and 8, while making sure from tables 1 and 5 that this combination provides the desired trim materials. Then, make sure from table 11, 12, or 13 that the valve body/trim temperature limits are not exceeded.

2. Finally, check in table 20 that packing and other valve parts are available in materials that meet the desired service conditions.

Installation

Unless limited by seismic criteria, the valve body can be installed in any position (as long as sufficient support is provided if a fabricated extension bonnet is used). However, the normal method is with the actuator vertical above the valve, since nonvertical positionsmaycauseuneventrimwearanddecreased trim life.

Flow through the valve body must be in the direction indicated by the flow direction arrow on the valve body. Consider installing an upstream strainer, especially if the valve body includes slotted or multihole Whisper Trim or Cavitrol cages.

Dimensions are shown in figure 20.
