VALQUA No. M591 - Spiral Wound Gaskets made of Mica filler (with outer ring)
VALQUA No. M591 - Spiral Wound Gaskets made of Mica filler (with 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:
- Spiral Wound Gaskets using mica film as filler material
- Minimizes the deterioration of strength due to heating.
- The circumferance of the outer ring of a gasket with an outer ring inscribes the bolt of the flange, making gasket centering easy. This ring is also useful as a guide for adjusting the amount of reinforcement and tightening of the gasket.
- This product is for use in high temperatures. Basically, No. M596 (with inner and outer rings) is recommended.
- Please use a product with inner and outer rings 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.
Applicable Fluids:
Water, Steam, Hydrocarbons, Gases, Lubricants and standard plant chemicals.
Inappropriate Fluids:
Inflammable gas, Poisonous
Typical Plant Applications:
For H.T.S.（Oxidizer: The mixture of Sodium nitrate, Potassium nitrate, and Sodium nitrite） used as high temperature Heat transfer oil
