Product Description

Fisher Whisper Trim I cages offer proven aerodynamic noise control

that is effective for vapor, gas, or steam flow applications.

The Whisper Trim I cage utilizes multiple orifices of a special shape, size,

and spacing to minimize noise generated by the flow of vapor, gas,

or steam through a control valve. Using a Whisper Trim I cage,

in conjunction with a properly sized valve body, can substantially

reduce the noise level below that of valves with standard trim.

Product Description

Whisper Trim III cages provide effective attenuation of aerodynamic noise in vapor, gas,

or steam applications involving high pressure drops or high pressure drop ratios.

Using a Whisper Trim III cage in conjunction with a properly-sized valve body

can substantially reduce the noise level of the control application.

Aerodynamic noise is generated by the turbulence created in the flow of

vapor, gas, or steam as the fluid passes through a control valve.

Features

• Use of a Whisper Trim III cage in a properly sized valve can result in a noise reduction

up to 30 dBA compared to the same valve with standard trim.

Such a reduction would be similar to the reduction in noise level noticed when moving away from the

noise

• Whisper Trim III cages provide excellent noise reduction and high flow capacity

with the proven control and durability offered by standard Fisher valve trims.

The result is optimum overall performance at a minimum investment.

• Quick change trim allows fast and easy inspection of the cage without

taking the valve body out of the pipeline.

Whisper Trim III is interchangeable with standard control valve trim.

• Hardened materials of construction are standard to provide exceptional wear resistance.

Features

• Broadband Noise Reduction — Patented design with internal acoustic cavities of varying

sizes reduce noise across a broad range of frequencies.

• Application Versatility — Designed for a wide range of fluid flow rates, pressures and temperatures.

Reduce noise inside the pipe for all sources upstream.

Pair the WhisperTube with any equipment used in compressible fluid service.

• Maximize Flow Capacity — Negligible pressure drop across the WhisperTube other than the normally

expected line loss for a pipe spool piece of equivalent length equates to noise attenuation with no impact

on process flow.

• Passive Reactive Silencer — Internal cavities produce acoustic wave reflections that reduce noise

propagating downstream.

• Reliable Performance — No internal acoustic packing material to fail from moisture absorption.

Cast internal drain channel ensures any potential liquid buildup can be removed, ensuring optimum

performance.

• Compatible with Piggable Systems — Straight through flow geometry with inside diameter

 that matches the pipe accommodates pigging operations when required for cleaning and maintenance.

• Sour Service Capability — NACE MR0103. MR0175 / ISO 15156 compliant materials of construction 

as standard for applications involving sour gas or vapor.

• Quick and Easy Maintenance — Removeable cylindrical stainless steel screen

for easy cleaning if required with no special tools needed.

• Easy Installation — Threaded lifting provisions accommodate fitting the body with hoist rings

or lifting eye bolts for optimized product control during installation.

Product Description

The WhisperTube is a passive reactive silencer designed for installation downstream

of the control valve or other equipment contributing to system noise.

Requiring negligible pressure drop across the device, the WhisperTube achieves system

noise reduction across a wide range of conditions without impacting the flow capacity or process.

Product Description

The Fisher easy-e ET valve is your solution for all general applications with

high process temperatures, featuring a balanced plug design and cage-guided trim.

Available in globe or angle body, these valves can provide up to Class V or VI shutoff.

Features

• ENVIRO-SEAL™ packing systems that provide an improved stem seal to help prevent

the loss of process fluid are available. These packing systems feature PTFE or Graphite

ULF packing with live-loading for reduced packing maintenance.

• Controlled compression of standard seat construction protects PTFE disk between metal

disk seat and disk retainer. Excellent shutoff is maintained by a backup ring or

spring-loading that forces the valve plug seal ring against the cage.

• Rugged cage guiding provides high valve plug stability,

which reduces vibration and mechanical noise.

• Increased wear resistance of hardened stainless steel trim means longer-lasting service.

• Valves are available with dimensions specified by EN/DIN standards.

• Unless otherwise noted, references are to NACE MR0175-2002. Optional materials are

available to meet NACE MR0103 and NACE MR0175 / ISO 15156.

Network Master Mounting

If the system is supplied from the factory in an NEMA enclosure, no internal wiring

is required except for connecting power and field network wiring. The next three

sections (Sections 2.1. 2.2 and 2.3) discuss mounting, power input and field network

wire connections to the NIM.

Mounting of NEMA Enclosure

The enclosure is rated for NAMA 4/12 and IP65/IP55. Dimensions of the enclosure are shown

in Figure 5. Mounting dimensions are shown in Figure 6. The enclosure may be bulkhead

mounted using the internal mounting holes. External mounting brackets may be used if

desired. When mounting using the internal mounting holes, caution must be used to ensure

the holes are sealed to maintain the NEMA/IP rating. The enclosure is supplied with five 1/2 in.

compression type cable entry hubs. These may be fitted with conduit type fittings if desired.

If the system includes backup LCD keypad terminal, some planning is required to allow for

proper height above the floor to view the display and properly operate the keypad.

Mounting of Rack Mount Enclosure

The enclosure is designed for standard EIA 19 in. DIN rail rack mounting. Dimensions of the

enclosure are shown in Figure 7. The enclosure conforms to EIA RS-310. IEC 297-1. and DIN 41

494. Part 1 standards. The rack in which the enclosure(s) are mounted must allow a minimum

of 20 in. / 508 mm depth, allowing space for cable connections. If the system includes backup

LCD keypad terminals, some planning is required to allow for proper height above the floor to

view the display and operate the keypad properly.
