VALQUA No. UF300

UNIVERSALHYPER™

This is a Sheet Gasket that can be used for the widest variety of fluids, and different applications are not required for acid or alkali fluids. It is effective for promoting gasket integration at a plant where both alkali and acid lines exist. This is a product that possesses high-temperature reliability equal to that of other High-performance Non-asbestos Sheet Gaskets (GF300, for example), thereby possessing both chemical resistance and high-temperature reliability.

Design Criteria
The values for Compressed Non-asbestos Fiber Sheets defined in Appendix G to JIS B 8265 can be applied to m and y values of High Performance Non-asbestos Sheets.

Thickness (mm)	Gasket factor “m”	Minimum design seating stress “y”(N/mm2)
3.0	2.00	11.0
1.5	2.75	25.5
1.0	3.50	44.8

Recommended Tightening stress(MPa)

The recommended tightening stress is the pressure required under standard conditions without consideration to the endforce due to internal
fluid. It is the stress on the contact area of the gasket
