This document specifies the characteristics of valves made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels.

It is applicable to unidirectional and bi-directional valves with spigot end or electrofusion socket intended to be fused with PE pipes or fittings conforming to EN 1555-2 and EN 1555-3 respectively.

The PE spigot or electrofusion ends for valves made of material other than polyethylene is intended to be in accordance with EN 1555-3.

It also specifies the test parameters for the test methods referred to in this document.

In conjunction with Parts 1, 2, 3 and 5 of EN 1555, it is applicable to PE valves, their joints and to joints with components of PE and other materials intended to be used under the following conditions:

  1. a maximum operating pressure, MOP, up to and including 10 bar 1 2;

    For the purpose of this document and the references to EN 28233, MOP is considered to be nominal pressure.

  2. an operating temperature of 20 °C as reference temperature;

    NOTE 1

    For other operating temperatures, derating coefficients can be used, see EN 1555-5.

  3. an operating temperature between −20 °C and +40 °C.

EN 1555 (all parts) covers a range of maximum operating pressures and gives requirements concerning colours and additives.

NOTE 2

It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

This document covers valve bodies designed for connection with pipes with a nominal outside diameter dn ≤ 400 mm.
