1. Seat in "LUBROSEAT" Acetal resin compound containing self-lubricating additives. Ideal for non-lubricating fluids. 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. “POWERAMMIDE”* stem bush It grants a perfect alignment of the shaft on the body and prevents oscillations with high pressure No seizing High number of cycles
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
6. Antistatic device (electrical continuity between ball, stem and body) Static electricity is avoided which can cause sparks and fire in an inflammable/explosive environment Contact safety throughout the entire life of the valve
PED Certificate Full compliance with European safety standards for pressure equipment (for DN ≥ 32)
Fire safe design Guarantees the tightness of the valve also in case of fire
Atex Certificate Installation is possible in a potential explosive environment
UP to SIL 3 certified Guarantee of the high level of functional safety
