1. Antistatic device (electrical continuity between ball, stem and body) Avoid electrostatic charges which could be a source of ignition in environments with flammable and/or explosive guaranteed Security of contact during the entire life of the valve 2. Double ring anti-friction Results in lower operating torque of the valve, Less wear compared to running a single ring 3. Package seals and with a "v" with 3 seals, plus o-ring It ensures a perfect seal even after a high number of cycles 4. The spring on the stem seal Ensure the recovery of the games due to wear and tear caused by the movement semirotatorio of the tree, avoiding leakage to the outside Allow you to keep energized the guarnizoini type "chevron" (V), avoiding leakage to the outside, in the face of significant temperature excursions 5. Seal elasticated graphite Provides a seal to the outside regardless of the temperature it is subjected to the valve

Greater precision in the alignment of the axes due to machining, from raw materials to finished with a unique placement Most of the life of the valve Lower drive torque Easy maintainability directly on the system Cost containment during the maintenance phase Valve body, carbon steel made with the material normalized certificate, NACE standard It guarantees a corrosion resistance Higher ductility of the material The production process carried out entirely in the OMAL Maximum control at all stages of processing Ability to quickly deliver a special order requested by the customer ATEX certificate It can be installed in the presence of a potentially explosive atmosphere Certification "TA LUFT fugitive emission" Ensures a high degree of safety of the stem seal to the outside Certificate PED Full compliance with european safety standards for devices in pressure
