Overview of Fusible Link Assemblies
• Automatic shutoff in case of fire or exposure
to elevated heat conditions
• Used in process lines to contain the media in
a safe location or in fire suppression systems

(1/4” through 24” sizes)
• For pipelines conveying flammable media in
either liquid or gas form
• Valve can be operated even while spring
pack is armed
• Remote shut-off options
• Torque output options to 21,000 inch pounds

How fire safe fusible link valves work
Fusible link
spring pack
1. The spring pack is armed in the full CCW
position. Note: the valve can still be
opened and closed manually even while
the spring pack is armed.
2. The fusible link holds the spring pack in
the designated position (for fail open or
fail close).
3. When the soldered fusible link breaks,
spring pack will rotate the drive coupler
and tripper arm clockwise no matter
what position the handle is in.

arm
4. Most applications are fail closed; once the
valve is in the closed position, it will cut
off the flow of flammable media to the
pipeline.

What makes a valve “fire safe”?
Integral tongue &
groove
1. Graphoil body seals prevent any leakage
past the ball or disc; graphoil stem packing
prevents leakage through the top of the
valve
2. Tongue and groove body seal design
3. Blow-out proof stem
4. Seats can be TFE, RTFE, PEEK, Nova or
Delrin
Graphoil seal
5. Meets API (American Petroleum Institute)
607 standards for withstanding extended
high temperature conditions without leakage
at full pressure rating
6. Metal-to-metal contact reduces threat of
leakage

Our design versus others you might encounter
1. True “industrial style” full
port ball valve, not a check
valve
2. Higher pressure ratings
3. Can be manually operated
4. Easy to re-set in the field
5. Simple maintenance and
repair of valves in the field
6. No need to remove ball
valves from the pipeline for
repair/maintenance
7. Can be retrofit to customerowned or plant-specified
valves

Options
1. Valve monitoring
2. Remote shut off
3. On-site installation with our technicians
4. Retrofit to customer-owned valves

SAMPLE APPLICATION #1: Marathon-Ashland
• Location: Canton, OH
• Application: fusible link assemblies
designed to fail close at a diesel truck refueling station
• Marathon had been using a competitor’s
non-industrial style fusible link on a 3”
pipeline and they were not holding up in the
application because of constant cycling
• Our assemblies have been in line for over 5
years without failure or maintenance
Specialty Safety Products: Fire Safe Valves
SAMPLE APPLICATION #2: SKF USA
• Location: Armada, MI
• Application: fusible link assemblies
designed to fail close on EDM (Electrical
Discharge) machines that are used to remove
material and reshape precision steel parts to
obtain desired finish and accuracy
• High flash points of electrodes/liquid in
process recently resulted in a fire at another
one of SKF’s locations. FM inspectors now
require BI-TORQ fusible link valves on each
port off of their dielectric tanks
• Four assemblies were installed last month
and approved by FM and OSHA inspectors
Specialty Safety Products: Fire Safe Valves
Optional Fusible Plug
• A cost-effective option when plant air is
available
• Used with a spring return pneumatic
actuator
• Functions open-closed as a standard
pneumatically actuated valve.
• Plug allows air to vent to atmosphere,
causing springs to turn actuator CW to
close
