This document specifies constructional, functional, testing, marking, sizing and documentation requirements of gas pressure regulators:
- for inlet pressures up to 100 bar and nominal diameters up to DN 400;
- for an operating temperature range from – 20 °C to +60 °C,
which operate with fuel gases of the 1st and 2nd family as defined in EN 437:2018 [1], used in the pressure control stations in accordance with EN 12186 or EN 12279, in transmission and distribution networks and also in commercial and industrial installations.
“Gas pressure regulators” hereafter will be called “regulators” except in the titles.
For standard regulators when used in pressure control stations complying with EN 12186 or EN 12279, the Annex ZA lists all applicable essential safety requirements of the European legislation on pressure equipment except external and internal corrosion resistance for applications in corrosive environment.
This document considers the following temperature classes/types of regulators:
- temperature class 1: operating temperature range from -10 °C to 60 °C;
- temperature class 2: operating temperature range from -20 °C to 60 °C;
- type IS: (integral strength type);
- type DS: (differential strength type).
This document applies to regulators which use the pipeline gas as a source of control energy unassisted by any external power source.
The regulator may incorporate a second regulator, used as monitor, complying with the requirements in this document.
The regulator may incorporate a safety shut off device (SSD) complying with the requirements of EN 14382.
The regulator may incorporate a creep (venting) relief device, complying with the requirements in Annex E and/or a vent limiter, complying with the requirements in Annex I.
