VALQUA No. 6592 - BLACKTIGHT (with inner ring)
VALQUA No. 6592 - BLACKTIGHT (with inner 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
- A gasket with an inner ring is used for a male-female flange. The inner ring not only reinforces the gasket but also decreases the clearance between the pipe's inner diameter and the gasket, as well as preventing accumulation of fluids and errosion of corner areas. Please use a product with an inner ring if the pressure rating of the flange is Class 900 (JIS 63K) or greater, or if the nominal diameter of the flange is 650A (26B) or greater.
- 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:
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.
