Non-OEM graphite packing does not measure up to the

ENVIRO-SEAL graphite ULF packing system as proven by

2001 Emerson lab testing at 1500 psi and thermal cycling

to 600°F without packing adjustment.

ENVIRO-SEAL packing systems have

been designed, tested, and validated

to extend control valve service life and

meet current environmental standards.

packing systems provide

the measure of emissions control security that you

require. They are designed and tested for Fisher

control valves to keep fugitive emissions below 100

parts per million volume (ppmv) in your throttling

application for tens of thousands of cycles.

Consider the Differences Between

Packing Test Standards

There are many fugitive emissions test standards,

all with a variety of testing methodologies and

passing criteria. Which standards best represent

your control valve applications?

Control valve test standards require

20,000–100,000 cycles

(ANSI/FCI 91-1 and ISO 15848-1)

On/Off valve test standards require

1,510 cycles

(API 622)

ENVIRO-SEAL packing systems have been

tested to control valve test standards such as

ANSI/FCI 91-1 and ISO 15848-1. In contrast,

non-OEM packing typically only adheres to

on/off valve test standards such as API 622.

Proven Solution for 20+ Years

Utilize proven ENVIRO-SEAL packing systems,

which have offered reliable fugitive emissions

sealing and long cycle life since the Clean Air Act

inception of Leak Detection and Repair (LDAR)

more than 20 years ago.

Packing Design is More Than

Controlling Fugitive Emissions

The design of packing systems requires an

understanding of the entire control valve

assembly. ENVIRO-SEAL packing systems are

designed and tested for your Fisher control

valves. You can meet 100 ppmv leakage and

realize low maintenance, long service life, and

optimal dynamic performance.

Non-OEM packing might meet your emissions

needs on the first day. In the long run, however,

unknown friction and dynamic performance

characteristics can impact your loop

performance and reduce your bottom line.
