14” Squib valve body designed by SPX and manufactured

with the quality of the castings
and we are working on ways
to increase production to
meet their demand.
As a further endorsement
of the success of the
SPX-designed, Bradken-
manufactured valve bodies,
the Squibs have met the
required performance tests
so well that the Nuclear
Regulatory Commission
has proclaimed them as
the preferred design for
reactor safety.
A great solution to an
important safety challenge!
The result of the SPX/Bradken
collaboration is a ‘Squib’ valve,
a single action valve designed
to permit the rapid release of
fluid retained under pressure,
typically in the range 1,000 to
10,000 psi.
In the case of a major
accident, an explosive plug
guillotines the shear gate
within the valve, allowing
the Boratic water cooling
system to flood the reactor.
Bradken’s Tacoma Foundry
has produced two Squib valve
bodies; the 14” body is rated
at 8,000 lbs and the 8” body,
5,000 lbs. SPX is delighted
It goes without saying that safety is a critical issue when it comes
to nuclear power generation. So when Westinghouse Electric Company
commissioned SPX Corporation to design specialised safety valves
for its state-of-the-art AP1000 nuclear reactor, it made sense for SPX
to engage Bradken’s expertise in casting.
