1 Full lift safety valve with spring loading. (IT) Model 95 Model 95 Model 995 Model 9 EN P ES Model 95 S P ES Model 95 S P ES S P ES S Model 995 Model 9 The valve works as an automatic pressure releasing regulator activated by the static pressure existing at the entrance to the valve and is characterized by its ability to open instantly and totally. Design in accordance with International Standard ISO -:00 Safety Valves. In accordance with the requirements of directive 9/3/EC. EC valve verification certified by: TÜV Internacional Grupo TÜV Rheinland, S.L. EC Type (Module D) EC examination report nº certified by: TÜV Internacional Grupo TÜV Rheinland, S.L. In compliance with the TEX 9/9/CE directive Protective equipment and systems for use in potentially explosive atmospheres. Other authorisations: ISCIR, ITI, NSTHOL,...etc. Specifications 90 angular flow. ctivated by direct action helicoid spring. Simplicity of construction ensuring minimum maintenance. Materials carefully selected for their resistance to corrosion. Internal body designed to offer favourable flow profile. Sealing surfaces balanced and making them extremely tightness, even exceeding EN - requeriments. Great discharge capacity. For liquids typically used with openings similar to proportional safety valves. uto-centering plug. Totally precise open and close. ll the valves are supplied sealed at the set pressure requested, simulating operational conditions, and are vigorously tested. ll components are numbered, registered and checked. If requested in advance, material, casting, test and efficiency certificates will be enclosed with the valve, and the instruction manual, in accordance with P.E.D.9/3 EC.
