Currently valid:
Optionally co-design standards:
This European Standard specifies requirements and test methods for valves of prefabricated thermally
insulated valve assemblies comprising a steel valve, rigid polyurethane foam insulation and an outer casing of
polyethylene for use in directly buried hot water networks with pre-insulated pipe assemblies in accordance
with EN 253.
This European Standard applies only to insulated valve assemblies for continuous operation with hot water at
various temperatures in accordance with EN 253:2009, Clause 1 and the valve assemblies with a maximum
operation pressure of 25 bar. For higher pressures, additional demands apply.
Guidelines for quality inspection are given in Annex A of this European Standard.
