1. 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
2. Double antifriction washer Less Breakaway Torque is granted Less wear comparing with the execution with the single washer
3."V" seals pack; 3 seals + o-ring It ensures a perfect tightness even after a high number of cycles
4. Spring washer on the shaft seal Guarantee of the recovery of the gap due to the wear caused by the rotational movement of the shaft avoiding leakage towards the outside part. Allow to maintain energized the "chevron" seals (V), thus avoiding any leakage to the outside, against huge temperature excursions
5. Stretch Graphite seal Tightness towards outside is granted, independently by the thermal excursions to which the valve is subjected
Greater precision in the alignment of axes due to a unique positioning in the process machining from raw material to finished valve Longer lifetime of the valve Less breakaway torque
Valve body in carbon steel made with NACE certified material as standard Greater corrosion resistance Greater ductility of the material
100% in- house manufacturing process technology Maximum control and accuracy in all the stages of the manufacturing process Flexibility in supply quickly special executions requested by customers
"Fire safe" Certificate Guarantees the tightness of the valve also in case of fire
ATEX Certificate Installation is possible in a potential explosive environment
TA LUFT fugitive emission Certificate High level of safety of the tightness towards the outside is granted
PED Certificate Full compliance with European Safety Standards for Pressure Equipment
UP to SIL 3 certified Guarantee of the high level of functional safety
