Sliding-Stem Control Valves

Fisher easy-e cryogenic valves are globe-style,

single-port, valves featuring stainless steel

construction materials and fabricated extension

bonnets. Fisher ET-C and EWT-C valves are

pressure-balanced, whereastheFisherEZ-Cvalveisan

unbalanced design. These cryogenic valves are

designed to provide throttling or on-off control of

liquids and gases at cryogenic temperatures as low as

-198_C(-325_F).

When required, these rugged valves can reliably

provide tight shutoff for special applications within the

chemical and hydrocarbon processing industries, such

as certain liquefied natural gas services.

The high-capacity ET-C and EWT-C valves with

pressure-balanced trim allow the use of smaller,

lower-cost actuators, reducing installed costs in

high-pressure and high-flow-rate applications.

The easy-e Valve Family

Thesevalvesarepartoftheversatile easy-e family of

industrial control valves. Special features include:

ET-C and EWT-C: Different cage/plug styles provide

particular flow characteristics for highly-specialized

applications. The standard cage comes in two

different flow characteristics: Jequal percentage

and Jlinear.

Bonnet and 585C Actuator

W6370--1

EZ-C: Interchangeable, restricted-capacity trims and

full-sized trims match a variety of process flow

demands for highly-specialized applications. The

standard plug is designed with three different flow

characteristics: Jequal percentage, Jlinear, and

Jquick-opening.

Features

Cryogenic Spring-Loaded Seal Ring–The seal ring

and associated valve parts in the ET-C and EWT-C

valves are specifically designed and manufactured

for excellent performance at low temperatures.

Stable Control–Rugged cage guiding in the ET-C

and EWT-C valves stabilizes the valve plug at all

points in its travel to reduce vibration, mechanical

noise, and the need for hydraulic snubbers.

Cost Effective Operation and Economical

Maintenance–Increased wear resistance of

hardened stainless steel trim means long-lasting

service. Balanced valve plug construction in the

ET-C and EWT-C valves permits use of smaller,

lower-cost Fisher actuators.

Piping Economy–Expanded end connections of EW

Series valves may reduce the need for line swages

while accommodating oversized piping

arrangements used to limit fluid flow velocities.

Cryogenic Design Features–The stainless steel valve

body and bonnet with fabricated extension are

designed to meet low temperature requirements.

Theuniquemetal-to-metal seat design provides

repeatable tight shutoff, reducing maintenance

costs.

Rugged Metal Seat–The metal-to-metal seat is

designed and manufactured to provide long-lasting,

reliable, tight shutoff at both ambient and

cryogenic temperatures without the need for

periodic lapping. This reduces the need for soft

seats, even in applications with stringent shutoff

requirements.

Fugitive Emission Protection–The optional

ENVIRO-SEALtpacking systems provide an

improved stem seal to help prevent the loss of

valuable or hazardous process fluids, and keep

emissions below the EPA limit of 100 ppm.

Additionally, these live-loaded packing systems can

provide long life and reliability at low temperatures

to help reduce maintenance costs and downtime.

Thoroughly Tested–Extensive cryogenic testing

during the development of the valve design reduces

the need for expensive cold testing for most

applications, which results in quicker delivery and

greater value.

Easy Maintenance–Quick-change trim, with a

clamped-in seat ring, reduces the disassembly/

assembly time. The valve body can stay in the

pipeline during removal of trim parts for inspection

or maintenance.

Sour Service Capability–For NACE applications,

consult your Emerson Process Management sales

office.

EZ-C: JMicro-Flute and JMicro-Flow trim

1. Valve size number is end connection size by normal trim size. For example, an NPS 6X4 EWT-C valve has NPS 6 end connections with NPS 4 trim (see table 4).

2. Do not exceed the pressure or temperature limits in this bulletin, and any applicable code limitations.

3. UHMWPE stands for ultra high molecular weight polyethylene.

4. A spring is used only with PTFE V-ring packing. A lantern rings replace the spring in other packing arrangements.

5. Down is in through the cage and out the seat ring (see figure 1).

6. Class V shutoff cannot be performed with water. The residual trapped moisture from testing with water can cause valve and trim damage from the ice crystals formed at below freezing

service temperatures.
