EN 1491:2000
(Main)Building valves - Expansion valves - Tests and requirements
General Information
- Abstract
This European Standard specifies, dimensions, materials and performance requirements (including methods of test) for expansion valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion valves are intended for fitting to the cold water supply of storage water heaters, having a maximum distribution temperature of 95°C, for all energy sources. Expansion valves do not control the temperature and alone does not constitute the protection required for storage water heaters.
