VALQUA No. 6596 - BLACKTIGHT (with inner/outer ring)
VALQUA No. 6596 - BLACKTIGHT (with inner/outer ring)
GENUINE VALQUA JAPAN QUALITY: Spiral Wound Gaskets use Non-Asbestos inorganic paper, VALQUAFOIL™ (expanded graphite) and VALFLON™ (PTFE) tape as filler materials, and exhibit good elasticity by means of a V-shaped hoop.
Key Features & Advantages:
- Version of Spiral wound gasket using VALQUAFOIL tape applied as filler material with inner ring and outer ring
- The outer ring of the gasket with an outer and inner rings is useful as a guide for adjusting the amount of reinforcement and tightening of the gasket, making gasket centering easy. In addition, use of an inner ring prevents the inner diameter of this gasket from deformation even if the gasket is tightened too much. For this reason, gaskets with inner and outer rings are the most reliable high-temperature/high-pressure gaskets that can be mounted on raised face flanges.
- Excellent airtightness greatly improves sealing performance against gas in general and vacuum.
- Excellent response to heat and pressure cycles reduces the frequency of retightening.
- They also have excellent radiation resistance (products complying nuclear power specifications are available).
Applicable Fluids:
Water, Sea water, Hot water, Steam,Crude oil, Alcohol, Animal & vegetable oil, Heat transfer oil,General solvent, Weak acid, Weak alkali,Strong oxidizing acid, strong alkali,Air, Nitrogen gas, Inert gas,Exhaust gas,Inflammable gas,Poisonous,Extremely low temperature liquids,
Inappropriate Fluids:
Oxidizing acids such as hot, concentrated sulfuric acid, concentrated nitric acid and oxygen.
Typical Plant Applications:
In particular best suited as gaskets for use handling high temperature & high pressure steam (except HTS), as well as very low temperature fluids such as LNG, liquid nitrogen and liquid hydrogen.
