| Subject of the standard: | This document specifies requirements and test methods for factory made thermally insulated bonded steel shut-off valve assemblies for hot water networks in accordance with EN 13941-1, comprising a steel valve, valve extension pipes, polyurethane (PUR) foam thermal insulation and a casing of polyethylene. This document applies to steel valve assemblies with an internal pressure of maximum 2,5 MPa. The principles of this document can be applied to thermal insulated bonded steel valve assemblies with internal pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure. The steel shut-off valve assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers. |
