• 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 regulator depends on the regulated pressure of the first regulator and on the pressure losses in the intermediate line; • the second regulator supplies a gas appliance.
• 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. Holes for screws, pins, etc., intended for the assembly of the regulators components and for their fixing shall not open into the gas ways. The thickness of the wall between these holes and the gas ways shall be at least 1 mm. Holes necessary for machining which join gas ways to the atmosphere, but which have no influence on the operation of the regulator, shall be permanently closed metallically. Appropriate additional sealing compounds may be used.
