Description
Subcategory Hercules manual
1. Seat in "MASTERAMMIDE"*
Less wear comparing with not modify seat
High resistance to stress
2. Stainless steel ball, coated with 40μm Hard Chrome
Longer seal life due to the low wear of the ball
3. "MASTERAMMIDE"* stem bush
It grants a perfect alignment of the shaft on the body and prevents oscillations with high pressure
No seizing
4. Elastomer O-Ring with a hardness of 90 Shore A
No deterioration with quick operations
4. Low-permeability O-ring "Rapid Gas Decompression"
Good resistance to explosive decompression
5. Stem in 17-4 PH H900
Increased mechanical strenght about 5 times more compared to a standard 316 S.S.
5. Shaft rolling
Less wear of the seals due to the low roughness (0,4 micron Ra) which facilitate the sliding of the shaft
PED Certificate
Full compliance with European safety standards for pressure equipment (for DN> 25)
