VALQUA

SPIRAL WOUND GASKET (SWG)

By winding VALQUAFOIL filler in the middle of inorganic fillers, these spiral Wound Gaskets have enhanced gas sealability with increased compatibility with flanges.Further, the inner filler and outer filler shuts off the oxygen supply, inhibiting the oxidation of VALQUAFOIL

6590 Series

This is a Spiral Wound Gasket using VALQUAFOIL (expanded graphite)
as filler material.
▶Excellent air tightness that significantly improves sealing performance for gas and vacuums.
▶Responds well to heat and pressure cycles, which reduces the
frequency of retightening.
▶They also have excellent radiation resistance (products complying
with nuclear power specifications are available).
▶They exhibit excellent sealing properties at very low temperatures.
(No.6596VC type has been developed for cryogenic use. Further
information is available upon request.)

6590VC Series

This is a gasket for extremely low temperature application, and it has
high sealability even at a low gasket stress by making the 6590 series
more flexible.
▶This product has excellent sealability under extremely low temperature conditions such as LNG.
▶A process that can seal even under low gasket stress is used.

7590 Series

Using VALFLON (PTFE) tape having excellent chemicals resistance as
filler material, these Spiral Wound Gaskets are more effective than
other filler materials in sealing corrosive fluids and air tightness, thus
are suitable as gas and vacuum seals.
▶Together with excellent corrosion resistance and a suitable selection of hoop materials, they can be applied to almost all fields of
fluid applications.
▶Excellent air tightness significantly improves sealing performance
against gas and vacuums.

M590L Series

This is a Spiral Wound Gasket made of expanded graphite filler and
cloth-less mica filler made by a special manufacturing process, and it
has excellent sealability and significantly improved heat resistance
due to an anti-oxidation effect on expanded graphite by the mica filler.
▶ Maximum service temperature is 750°C.

M590 Series

This is a Spiral Wound Gasket using a clothless mica filler. The product
minimizes strength deterioration due to heating.
