DIN EN 15081:2008-03 : EN 15081:2007 (E) 4 1 Scope This European Standard provides requirements for metallic mounting kits for
18、 part-turn on-off valves and actuator attachments to enable safe and reliable operation. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm (up to F30 flange type). It applies to part-turn valves and actuators having attachment flang
19、es and drive components as described in EN ISO 5211. It includes recommendations and methods for design and environmental corrosion protection. When reference is made to this European Standard, all the requirements apply, unless otherwise agreed between the purchaser and the manufacturer/supplier, p
20、rior to order. For the scope of this European Standard, the term “Valve” covers valve or shaft extension top-flange. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated ref

26、e transmitting the drive torque to the obturator 3.8 part-turn actuator attachment attachment interface of the actuator which includes: flange necessary to attach the part-turn actuator to the intermediate support; driving component of the part-turn actuator necessary to attach it to the coupling or
27、 to the driven component of the valve, which may be an integral part or a removable component of the actuator 3.9 maximum actuator output torque maximum output torque of the actuator available at the maximum motive energy input 3.10 maximum allowable shaft torque (MAST) maximum torque that can be ap
28、plied to all the driven components, without damage and/or plastic deformation being sustained by any part 4 Design requirements 4.1 General Part-turn actuators shall be in accordance with EN ISO 5211. 4.2 Materials Unless otherwise agreed, mounting kit materials shall be: for intermediate supports,
29、of cast iron (CI), carbon steel (CS) or stainless steel (SS); for coupling, see performance classes (Table 2); for bolting (environmental corrosion categories according to Table 1): categories C2 and C3: stainless steel or a suitably corrosion protected carbon steel; categories C4 and C5-I: stainles
30、s steel; other categories: material to be specified by the purchaser. Special care shall be taken for material selection, in the event of environmental critical conditions. DIN EN 15081:2008-03 :EN 15081:2007 (E) 6 4.3 Design temperature The mounting kit shall be designed for operation at an ambient
31、 temperature range between 20 C and + 60 C. 4.4 Environmental corrosion protection Mounting kits shall be protected against corrosion by suitable material selection and/or surface treatment. The manufacturers technical documentation shall specify the choice of the materials and/or the type of the su
32、rface treatment. Surface treatment system for carbon or low-alloy steels (e.g. according to EN 10025) shall be chosen according to the classification categories given in Table 1. Test assessment and test procedures are the responsibility of the manufacturer. NOTE Table 1 may be used to define the co
33、rrosion category and help the mounting kit manufacturers to define the surface treatment for corrosion protection. Table 1 Environmental corrosion categories Typical environments Corrosion category Exterior Interior C2 (low) Atmospheres with low level of pollution. Mostly rural areas. Unheated build
34、ings where condensation may occur, e.g. depots, sport halls. C3 (medium) Urban and industrial atmospheres, moderate sulphur dioxide pollution. Coastal areas with low salinity. Production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries. C4 (high) Ind
35、ustrial areas and coastal areas with moderate salinity. Chemical plants, swimming pools, coastal shipyards. C5-I (very high - industrial) Industrial areas with high humidity and aggressive atmosphere. Buildings or areas with almost permanent condensation and with high pollution. C5-M (very high mari
36、ne) Coastal and offshore areas with high salinity. Buildings or areas with almost permanent condensation and with high pollution.

37、as and offshore structures. Im 3 (buried in soil) Buried pipelines NOTE This table is taken from EN ISO 12944-2:1998. 4.5 Mounting kit 4.5.1 Stiffness The dimensions of the mounting kit given in this European Standard ensure that the maximum flange torque - given in Table 1 of EN ISO 5211 - can be t
38、ransmitted safely. For non-vertically mounted actuators, the user may need to design an extra support. DIN EN 15081:2008-03 EN 15081:2007 (E) 7 When specified by the purchaser, the mounting kit shall also be designed for external loads (e.g. stepping load, earthquake, wind loading, additional plant
39、induced dynamic loads). In this case, for instance, the thickness as given in Table 3 may be increased. 4.5.2 Intermediate support style The intermediate support provides two equal or different attachment interfaces (actuator and valve), as per EN ISO 5211. The most common type is a “rectangular” br
40、acket, as defined in 5.1. The “rectangular“ type is predominantly manufactured from a rectangular or square tube in compliance with EN 10219-2 or EN 10210-2. The “rectangular“ type can also be cast, fabricated or machined. Other commonly used types are the following: “adapter flange”: generally manu
41、factured as one piece from casting, forging, plate or bar. It shall be provided with a suitable venting device; “spool type“: generally manufactured from two flanges that correspond to the mating faces of valve and actuator, connected together by a piece of tube. The assembly is welded together to f
42、orm a spool piece. The “spool“ type can also be in one piece: cast, forged or machined. The spool shall be provided with a suitable venting device and/or with a suitable opening to visualise the coupling position. Other types of intermediate support may be used provided they meet the requirements of
43、 this European Standard. 4.6 Coupling The design of the coupling shall ensure the maximum transmissible torque (as specified in EN ISO 5211), can be delivered to the valve shaft. The coupling performance class shall be specified by the purchaser in accordance with Table 2. The design of both couplin
44、g ends (driven/driving) shall avoid any contact between moving and fixed parts.

46、 support material as per 4.2 (CI, CS or SS); b) flange designations according to EN ISO 5211 (actuator flange type/valve flange type); c) coupling drive identification (first for the actuator and second for the valve): DIN EN 15081:2008-03 :EN 15081:2007 (E) 8 coupling driven (actuator side) diagona

NOTE The designation is not a marking requirement. 4.8 Position indicator The coupling design shall have a provision
49、 for a clear and permanently marked indicator to show whether the valve is open or closed: special attention, during the assembly, should be taken when installing square drive couplings. 4.9 Buried service When buried service is required, design details and corrosion protection shall be agreed between the purchaser and manufacturer/supplier. 4.10 Safety requirement (mechanical/thermal protection) The adapter flange or the spool shall have a provision for venting any leakage that may occur through the stem seal of the valve
