1 Normal safety valve with spring loading. (AN) EN Model 9 EP AP ES CP he 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, at the first proportional to the pressure increase, and after instantly and totally. Design in accordance with Internatinal Standard ISO 1-1: 0 Safety Valves. In accordance with the requirements of directive 97/23/EC. EC valve verification certified by: ÜV Internacional Grupo ÜV Rheinland, S.L. EC ype (Module D) EC examination report nº certified by: ÜV Internacional Grupo ÜV Rheinland, S.L. In compliance with the AEX 9/9/CE directive Protective equipment and systems for use in potentially explosive atmospheres. Other authorisations: ISCIR, II, NASHOL,...etc. Specifications 90 angular flow. Activated by direct action helicoid spring. Simplicity of construction ensuring minimum maintenance. Materials carefully selected for their resistance to corrosion. With the exception of washers and couplings, the valves are free of non-ferric materials. Internal body designed to offer favourable flow profile. Sealing surfaces treated and balanced, making them extremely tightness, even exceeding EN requeriments. Great discharge capacity. For liquids typically used with openings similar to proportional safety valves. Equipped with draining screws for removing condensation. Auto-centering plug. hreaded shaft with lever positioner facilitating immediate manual action. Elevator, independent of the seal, designed facilitate sudden opening when the steam expands and, with any fluid, guarantees absolute opening and closing precision. All the valves are supplied sealed at the set pressure requested, simulating operational conditions, and are vigorously tested. All 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.97/23 EC.

With external constant backpressure, the spring is adjusted deducting the backpressure from the set pressure. If the set pressure < 3 bar we must consider the total atmospheric pressure (1bar) as external constant backpressure being freely released. If pa > 5p, we must limit plug speed with the consequent reduction of the αd coefficient of discharge. With the new reduced coefficient we determine the d0, in order to remove the necessary volume. pa = Backpressure permitted [bar] absolute. pa = Set pressure [bar] absolute. αd = Coefficient of discharge.
