FUGITIVE EMISSION QUALIFICATION
The importance of fugitive emission (FE) testing and qualification
In a typical petroleum plant, 60% of fugitive emissions are from valves. Therefore it is extremely important to reduce
valve emissions to the greatest degree possible. The four widely recognized standards regarding valve fugitive
emissions for gate and globe cast steel valves are API 622, API 624, ISO 15848-1 and ISO 15848-2.
API 622 ISO 15848-1

The primary intention of API 622 is to qualify performance The primary intention of ISO 15848-1 is to type test the

Testing of Rising Stem Valves Equipped with Flexible Graphite Packing for Fugitive Emissions. Test reports
and performance results are available on request. All valves marked API 624 on the valve nameplate or on
a separate permanent metal tag fully conform to the requirements of API 624. All Velan API 600 and 623
valves use low FE packing certified to API 622.
We further certify that Velan API 600 gate and API 623 globe valves have been designed in accordance
with generally accepted good engineering practice for low fugitive emissions. Our valves have been type
tested pursuant to recognized fugitive emissions qualification standards including API 624 and ISO-15848-1
and have been found to have fugitive emissions lower than 100 ppmv. This certification is based on
extensive laboratory testing as well as field experience with regards to emissions performance of our
valves. Note that valves greater than 24” and API 594 check valves do not fall under the scope of the API
624 standard so the valves are not marked API 624 but utilize the same low fugitive emission technology.
To ensure low fugitive emissions throughout the operating life, valves must be used in accordance with
Velan’s installation, operating, and maintenance manuals. In particular, it is important that gland and body-
bonnet bolting is adjusted to recommended values and that stems are kept clean to prevent external dirt,
grit, sand and other materials from damaging packing or stems. The corrosion resistance of the valve
components in relation to the application requirements must also be considered during valve selection.

DESIGN OF STEM SEALS
Velan offers standard cast steel bolted bonnet gate and globe valves that are
qualification tested for compliance with EPA fugitive emissions regulations,
API 622, API 624, as well as ISO 15848-1
The Velan stem seal evolved from these test findings:
Standard stem l Ensures leakage of less than 100 ppm as
demonstrated through extensive laboratory testing.
l Velan’s low emission valve technology meets latest
standards requirements, with a design optimized for
extended service life:
a. Lower compression packing design reduces friction
and allows more room to re-torque in the field;
b. Rugged packing gland to withstand continued
field maintenance and provides lower total cost of
ownership;
c. Optimized packing ring construction for excellent
sealing and a corrosion inhibitor which demonstrat-
ed no corrosion indication based on API 622 tests.
l Tight clearances and tolerances between vital parts.
l Precision stem and packing chambers.
Straightness, roundness, and fine finish of the
stem and packing chamber wall are essential.
l Short and narrow packing chambers improve sealing.
l Stem and packing chamber walls.
Superior burnished surface finish for the stem
and packing chamber.
l Hardened stem for longer life.
Live-loading Live-loading Live-loading options

with leak-off
Velan has extensive experience in valve live-loading.
The original live-loading concept was developed
by Velan in 1972 in a research project for AECL to
eliminate leakage in nuclear service. Velan has been
supplying live-loaded valves for Nuclear and non-
nuclear service for over 40 years.
l Live-loading.
Two sets of belleville springs extends the low
emission service life especially in service with
large pressure/ temperature transients or frequent
cycling.
l Leak-off.
For critical service, a lantern ring and double
packing can be provided with a leak-off connection.
The leak-off is provided to allow collection of
leakage from the lower packing set.

VELAN CAST STEEL API 623 GLOBE & STOP CHECK VALVES
BOLTED BONNET CAST CARBON, STAINLESS OR ALLOY STEEL
NPS 2–24 (DN 50–600), ASME CLASSES: 150–1500
Design features
Unique non-rotating design
l Non-rotating stem with precision ACME threads
(Easily adaptable for actuation) and burnished finish. Valve suitable for horizontal
installation.
l Universal trim.
13Cr stem, 13Cr faced disc, and CoCr alloy faced seats
API Trim 8 suitable for service up to 850°F (454°C).
l Seat face CoCr alloy hardfaced, ground, and lapped to
a mirror finish. Conical seat machined to fine surface
finish.
l Tapered disc.
Body guided disc accurately mates the hardfaced
surface of the disc with the surface of the seat,
hardfaced with 13Cr, CoCr alloy, SS 316, or Monel,
ground and lapped with seat.
Disc in SS 316 hardfaced with CoCr alloy also
available.
NPS 2–6 (DN 50–150) valves may have solid
CA15 (13Cr) discs.
l Body and bonnet.
Castings are precision machined. One-piece bonnet
for better alignment, fewer parts.
l Stuffing box machined to fine surface finish.
l Body and bonnet joint accurately machined to fine
surface finish. Fully enclosed gasket. Gasket materials
on page 4. Details on page 9.
l Gland has two-piece construction for easy alignment.
l Rotating stem nut.
Austenitic ductile iron Gr. D-2C, renewable in-line.
l Torque arm reduces wear on packing rings and
enables better sealing and reduces torque.
l Impactor handwheels.
Globe and stop check valves require higher closing
torques than gate valves with the same seat diameter
and pressure class. The most economical mechanism
for tight shutoff is the impactor handwheel. Two
CONICAL SEAT lugs cast under the wheel strike simultaneous blows
and give 3–10 times the closing force of standard
handwheels. Impactor handwheels are supplied at
manufacturer’s option unless specified by customer
(see page 21).
All sizes and pressure classes
l Flanges:
have conical seats.
ASME Classes 150–300: 1⁄16” raised face.
ASME Classes 600–1500: ¼” raised face.
For Bellows seal valves see our on-line catalog (VEL-BS) Finish 125–250 AARH for all valves.

PRESSURE CLASSES: 150–1500
The production, transport, and storage of liquefied gases such as oxygen,
nitrogen, argon, natural gas, hydrogen, or helium (down to -425°F/ -253.9ºC)
presents several technical problems. Velan specially-adapted extended
bonnet cast valves offer safe and efficient service.
Materials
l Body and bonnet: Austenitic stainless steel castings used for bodies
and bonnets offer excellent impact strength, minimal heat loss, and
protection against corrosion.
l Stem: Austenitic stainless steel. To reduce galling, stems are also
offered in A479 grade XM-19 with high toughness even at extreme low
temperatures, excellent low friction, and galling-free movement at points
of stem contact.
l Wetted parts: all Austenitic stainless steel and CoCr alloy.
l Stem nut/yoke bushing: Austenitic ductile iron Gr. D-2C.
l Packing: PTFE or graphite packing protected from freezing by
a column of insulating gas.
l Seating faces: CoCr alloy is used to prevent seizing and galling.
When extremely tight shutoff is required, globe and check valves
are supplied with Neoflon, PTFE, or other soft inserts.
l Bolting: Strain-hardened Austenitic stainless steel.
GLOBE VALVE l Lubrication of stem nut: Exxon Nebula Lubriplate No. 930-AA
or Shell Darina EPI or equivalent.
Design features
l Extended bonnets with sufficient gas column length, usually specified
by customer, are supplied for all valves to keep the stem packing at
sufficient distance away from the cold fluid to remain functional.
l Flexible wedges with CoCr alloy seating faces for cryogenic service.
l Neoflon inserts are available for globe, piston, and swing check discs.
l Cleaning: All cryogenic valves are thoroughly degreased and cleaned and
pipe ends are sealed to prevent contamination.

Cavity over-pressurization protection

Block and bleed valves are capable of trapping fluid in the cavity between the
seats when in the closed position. If subjected to an increase in temperature,
an excessive build up of pressure can occur, which may result in a pressure
boundary failure. It is the responsibility of the user to assure that measures are
taken to prevent the pressure from exceeding the rating of the valve.
Cavity over-pressurization protection is not provided by Velan, unless speci-
fied. Velan can provide alternative solutions to safeguard against cavity over-
pressurization. Please contact us to determine the correct solution for your use.
