VALQUAFOIL
Ring Packing
Ring packing molded with expanded graphite powder or tape using
tooling for specified dimensions. Available in standard, quick
removal and lubricant-treated types. |
Used as a stem seal for valves against water, steam, oil, acid,
alkali, heat medium, solvent and gas (except oxygen, oxidizer, oxidized acid) applications. Usually used in
combination with adapter packings such as No.VFC-25 and 6399L.
Temperature limit :

| VF-10AE |
Nuclear VALQUAFOIL
VALQUAFOIL ring packing equivalent to No.VF-10 except that soluble
chlorine (including fluorine) is controlled below 100 ppm. |
Used as a stem seal
for nuclear valves for BWRs and PWRs.
Operation limit :
350, 17.2 MPa (up to the maximum specifications of PWR) |
VF-20
VF-20L
VF-20LF |
VF Braid
No.VF-20 is a coil packing made of expanded graphite yarn reinforced
with Inconel wire and braided into a square cross-section. No.VF-20L
and VF-20LF are of low-torque type treated with lubricating oil
and special unification treatment, respectively. No.VF-20LAE is
also available for nuclear valves. |
Used as a stem seal
for valves against water, steam, oil, acid, alkali, heat medium, solvent
and gas (except oxygen, oxidizer, oxidized acid) applications.
Usually used in combination with adapter packings such as No.VFC-25
and 6399L.
Temperature limit :
650 (under air of 400) |
For
:
3 25m
Length :
3m |
| VF-22 |
VF Braid
No.VF-22 is a coil packing made of expanded graphite yarn braided
into a square cross-section. |
Used as a stem seal for valves and a shaft for pumps, rotary
and reciprocating equipment against water, steam, oil, acid, alkali, heat medium, solvent and gas (except
oxygen, oxidizer, oxidized acid) applications. Used in combination with adapter packings such as No.6345 and
1110 for reciprocating and high-pressure applications. |
VF-25
VF-25L
VF-25LF |
VF Braid
No.VF-25 is a coil packing made of expanded graphite yarn reinforced
with Inconel wire, braided into a square cross-section and cladded
with Inconel wire on its surface to increase strength. No.VF-25L
and VF-25LF are of low-torque type treated with lubricating oil
and special unification treatment, respectively. |
No.VF-25 is used as
a stem seal for valves and an adapter for No.VF-20 and VF-20L
(Packing for adapters only). No.VF-25L may be used independently.
Temperature limit :
650 (under air of 400) |

Carbon Fiber
Reinforced VF Braid
No.VFC-25 is a coil packing made of expanded graphite yarn reinforced
with carbon fiber and Inconel wire, braided into a square cross-section
and processed with special lubrication treatment. |
No.VFC-25 is used
as a stem seal for valves and an adapter for No.VF-10 and VF-20
(Packing for adapters only).

VF Braid
No.VFT-22 is a coil packing made of expanded graphite yarn reinforced
with carbon fiber and Inconel wire, braided into a square cross-section
and processed with special lubrication treatment. It is a gland
packing that makes full use of the characteristics of each material. |
Used as a stem seal for valves against water, steam, oil, acid,
alkali, heat medium, solvent and gas (except oxygen, oxidizer, oxidized acid) applications.
Temperature limit :
300 |
