VALQUA No. 6590 - BLACKTIGHT (basic design)
VALQUA No. 6590 - BLACKTIGHT (basic design)
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:
- Spiral wound gasket using VALQUAFOIL tape applied as filler material
- The basic-shape gasket is used for male-female and tongue and groove flanges, bonnets of valves, as well as covers for pressure vassels, towers, and tanks. It only requires a narrow width, and safe for use under high pressure.
- 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.
