When it comes to valve packings, you look for products that are resistant to high pressures, temperatures, chemicals, and fire — but what about compliance with Volatile Organic Compounds (VOC) Emissions Regulations? According to the Ecological Society of America (ESA) half of all fugitive emissions come from chemical and hydrocarbon processing facilities — with valve stem leaks accounting for 60% of these emissions.

Garlock's advanced sealing concepts dramatically reduce fugitive valve stem emissions. From Garlock 9000 Expandable Valve Stem Packing (EVSP) Simplified™ to Garlock Style 1303-FEP compression packing, our products are tested to meet every code and requirement: bringing your valves into compliance with Federal VOC emission requirements and State Implementation Plans (SIP). Let our trained and experienced engineers provide a comprehensive survey of your equipment and processes — and recommend products that can provide solutions to potentially costly fugitive VOC emissions applications.

General Sealing Guide
Garlock valve packings not only provide proven sealability to comply with Volatile Organic Compounds (VOC) Emissions Regulations, but also have tested resistance to high pressures, temperatures, chemicals and fire. They are tested to meet every code and requirement. These advanced Garlock sealing concepts will bring your valves into compliance with Federal VOC emission requirements and State Implementation Plans (SIP).

Garlock Valve Stem Solutions
Environmental compliance is an objective that every company shares, but one that is particularly important to chemical
and hydrocarbon processing facilities. According to the Ecological Society of America (ESA) half of all fugitive emissions
come from these two process industries. The same ESA study identifies valve stem leaks as the leading source of fugitive emissions, accounting for 60% of emissions. To that end Garlock has created products whose sole purpose is to dramatically reduce fugitive valve stem emissions.

Environmental compliance is just one reason to cut emissions though. If a facility is already meeting mandated emissions level, why go farther? The answer is that while an active Leak Detection and Repair (LDAR) program has the obvious benefit of bringing your operation into compliance with environmental standards it also produces a stream of tangible and intangible benefits that go far beyond merely satisfying environmental regulations.

For example, cutting emissions improves production yields which, in turn increases operating profits.

Further, in an age of Marketable Pollution Permits, cutting emissions below mandated levels allow an operation to sell its unused emissions units. This not only improves operating profits, but creates a competitive advantage in that it increases
the cost of competitors' operations.

Operating efficiency is also improved as a result of creating a safer, and therefore more productive, workplace. Fewer lost time accidents and a proactive environmental program will also help your operation be perceived as the employer of choice and as a leader in the community.

Style 9000 EVSP
Garlock Expandable Valve Stem Packing or EVSP is the ideal solution for applications where fugitive emissions have to be less than 100 PPM, fire safety or chemical resistance are required or where adjusting the packing load is not feasible.

EVSP's outstanding sealing characteristics surpass the emission standards of today and will meet the standards of tomorrow.

The low friction design allows for easy actuation and results in a more efficient use of instrument air plant resources. EVSP's superior radial expansion characteristics will seal even older, worn valves. This means that emissions compliance can be achieved throughout the plant without the capital cost of replacing valves or the maintenance expense of bringing valves back into manufacturer's specifications.

In addition to making the seal fire safe and chemically resistant, the densified graphite construction resists volume loss, meaning that a valve packed with EVSP will be in service for years to come.

Style 1303-FEP
If measuring all the stuffing boxes of all the valves prior to installation is not a realistic option, then Garlock Style 1303-FEP spool stock is a great alternative to EVSP. This proprietary wire reinforced graphite packing provides the low emissions levels of an engineered set with the installation flexibility and speed that comes from braided packing. Style 1303-FEP offers the same fire safety and chemical resistance as EVSP.

The wire reinforced construction makes for a long lasting valve packing that requires minimal adjustment and will deliver superior emissions control from turn around to turn around. What's more, the wire reinforcement will not score the stem and doesn't add excessive stem friction. In a recent independent 3000 cycle test conducted at Yarmouth Research and Technology, Style 1303-FEP not only provided marked improvement in emissions control, but it also required 60% fewer adjustments and 4% less actuation torque as compared to the next best competitive braided emissions packing.

Style 1303-FEP is available in a wide range of cross sections so that it can be used in virtually any valve. Further, with our world class manufacturing facility and supply chain, 1303-FEP can be delivered in one day.
