SR EN 334:2019

Gas pressure regulators for inlet pressure up to 10 MPa (100 bar)

This European Standard 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 437:2003+A1:2009, used in the pressure regulating 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 regulating 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 °
