Stop valve with bellow seals, maintenance-free, designed with external spindle and support guide, thus avoiding the atmospheric emissions of conventional valves.
Treated closing surfaces, which are grinded, lapped and burnished in order to achieve a degree of leak-tightness that
even exceeds that required by EN 12266-1 class A.
All the valves are rigorously tested and verified.
All components are numbered, registered and checked. If requested in advance, material, casting, test and efficiency
certificates will be enclosed with the valve, and with the instruction manual, in accordance with P.E.D. 2014/68/EU.
