Fisher™ 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
gas reducing stations where sonic velocities are often
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 sales office
include the applicable codes and standards required
for these environments.

and

The easy-e Valve Family

EW Series valves are part of the versatile easy-e family
of Fisher industrial control valves. easy-e valves share
the following characteristics:

n Multiple trim material choices

n Trim temperature capability with metal seats

standard to 427_C (800_F)

n Interchangeable, restricted-capacity trims and

full-size trims to match variable process flow
demands

W2777-1

n 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

n Cavitrolt III cages are available to eliminate

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

n 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

(PolyEtherEtherKetone) anti-extrusion rings in
combination with a spring-loaded PTFE seal. The PEEK
anti-extrusion rings expand to close off the clearance
gap between the plug and the cage where the PTFE
seal may extrude at high temperatures and pressures.
The temperature limits are extended to 316_C (600_F)
for non-oxidizing service and to 260_C (500_F) for
oxidizing service.

Features

n 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
feature PTFE or Graphite ULF packing with
live-loading for reduced packing maintenance.

n 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.

n Temperature Compensation—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.

n Standard Trim Parts across the easy-e product

line—Included are FGM gaskets, packing flange,

studs, and nuts.

n 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).

n 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.

n 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 17) 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

18) 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.

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, because non-vertical
positions may cause uneven trim wear and decreased
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 19.

NOTES:

1

Be especially careful to specify service temperature fi trim 3,4, or 37 is selected, as different thermal expansion rates require special plug clearances, also, use trim 37H
instead of trim 4 for non-lubricating fluids such as superheated steam or dry gasses between 149°C (300°F) AND 316°C (600°F).
Do not exceed the maximum pressure and temperature for the class rating of the body material used, even through the trims shown may have higher capabilities.

2
3

Use trim 27 instead of trim 29 for non-lubricating fluids such as superheated steam or dry gasses between 149°C (300°F) AND 316°C (600°F).

4

Trims 4 AND 29 may be used over 300 PSI only with clean, dry gas.

EWD, EWS, and EWT NPS 12x8 CL900 limited to CL600 pressure drops. See figure 9 and 10 EWD-1, EWS-1, and EWT-1 for full CL900 NPS 12x8

trim sizes. Maximum travel is 2 inches

1. For CL900 valve bodies, only the plain bonnet is available. Consult your Emerson sales office for assistance if application conditions indicate the need for an extension bonnet for a CL900
valve body.

2. These in-body process temperatures assume an outside, ambient temperature of 21_C (70_F) and no insulation on the bonnet. When using any packing at low process temperatures, a cast
extension bonnet may have to be used to prevent packing damage which could result from the formation of valve stem frost. Material selection for trim and other components will also be
limiting factors.
