HKS
original
3-chamber
structure
ensures
the
stable
operation
of
blow-off
valve
regardless
of
the
amount
of
pressure.
Large
51mm
valve
performs
great
with
high
power
and
large
displacement
engines.
Adjustable
pre-load
allows
a
wide
range
of
application.
Typical
blow
off
valves
require
spring
load
settings
for
each
vehicle
specification.
If
the
spring
load
setting
is
too
low,
the
boost
pressure
may
be
relieved
under
high
boost,
and
the
desired
boost
setting
may
not
be
reached.
If
the
spring
load
setting
is
too
strong,
the
valve
may
not
open
at
low
boost.
HKS
RACING
SQV
utilizes
a
reliefless
type;
therefore,
it
delivers
stable
operation
at
all
boost
levels.
Durability
tests
of
over
1
million
operations
minimizes
the
chances
of
valve
stick
and
achieves
high
durability.
