• the supply pressure of the regulator is equal to the pressure of the LPG supply container(s); • the regulator supplies a gas appliance. 2 – Two stages
• the supply pressure of the first regulator is equal to the pressure of the LPG supply container(s); • the supply pressure of the second and the third regulator depends on the regulated pressure of the upstream regulator and on the pressure losses in the intermediate upstream line; • the third regulator supplies a gas appliance. 4.2 Regulators for installations where the final regulator supplies a pressure specified in EN 437 The last regulator, which supplies a gas appliance for pressures specified by EN 437 shall be a fixed regulator (see 3.1.2). It is recommended that all the other regulators of the installation are fixed regulators. For interchangeability the recommended nominal value of intermediate regulated pressures (pd) are the following: 3 – 1,5 – 1 – 0,75 – 0,5 – 0,4 – 0,3 – 0,15 bar These settings accommodate pressure losses in the interstage pipe work. In general systems are designed with a pressure loss of up to 15 %. However in some cases where additional equipment (i.e limiter) is fitted, pressure losses of 50 % are found. 4.3 Other regulators To supply appliances with pressures which are different from those specified by EN 437 fixed, variable or adjustable regulators are used. 5 Constructional characteristics 5.1 General Regulators shall be designed, manufactured and assembled in such a way that their operation is satisfactory under the installation and service conditions specified by the manufacturer. The safety devices, if incorporated in or onto the regulators covered by this document shall be designed and constructed in accordance with the provisions of annexes A and B. All the parts of a regulator shall be free from sharp corners or edges capable of causing damage, deterioration, injury or faulty operation. Parts shall be clean internally and externally. SIST EN 13785:2005+A1:2009
200 mbar and of a rate smaller than 4 kg/h, directly fitted onto the cylinder using a quick coupling with self closing valve and non threaded outlet connection, non metallic (thermoplastic or thermal setting) materials may be used if the characteristics meet the requirements of this document as well as the complementary special requirements defined in annex E. Internal parts and parts of the cover not relating to pressure (except for connections, see Figure 2) may be made of non metallic (thermoplastic or thermal setting) materials provided that they meet the following requirements: the materials used shall meet the requirements of annex E; the whole regulator shall withstand the various tests specified in the body of the document; the regulator, with non metallic parts removed, shall resist a pressure test as in 7.2.2.3 remaining sound in the sense of 5.5 and without causing any danger. !Zinc alloys shall only be used if they are of the Zn Al4 or Zn Al4 Cu1 quality, in accordance with ISO 301. Brass alloys shall comply with EN 12164 or EN 12165. SIST EN 13785:2005+A1:2009
