Long-Term, Low-Emissions Performance with Fisher® ENVIRO-SEAL™ Packing Systems

Fisher® ENVIRO-SEAL™ 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.

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.
