VALQUA No. Name/Description Application Size
VF-10 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 :
650 (under air of 400)
Molded ring
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
Molded ring
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 :
325m

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. For :
325m

Length :
3m
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)
 For :
3-25 mm

Length :

3m
VFC-25 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).
Temperature limit :
650 (under air of 400)
 Molded ring
VFT-22 PTFE-covered VF Braid
No.VFT-22 is a coil packing made of expanded graphite yarn covered with PTFE film, 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
