Technical aspects of the DIN 3502 standard application
The DIN 3502 standard regulates the requirements for the design and operation of shut-off valves used in modern water supply systems. The standard is closely correlated with the provisions of DIN EN 1213 and defines the design features of valve bodies equipped with a through-hole or functioning without one.
The engineering solution, which provides for the possibility of emptying the hole at an angle to the central axis of the pipeline in the stationary upper part, makes this type of equipment optimal for implementing shut-off units in drinking water distribution systems. The equipment is effectively used both in capital engineering structures and in external distribution networks, ensuring reliable flow shut-off.
Design features and operational characteristics
A key advantage of valves compliant with the DIN 3502 standard is the inclined configuration of the upper part of the valve (type PN 10), which significantly optimizes the hydrodynamic flow indicators and reduces the risk of stagnant zones in the system.
EV Group China experts emphasize that the use of these valves allows for a significant increase in the overhaul interval of engineering networks due to the use of high-quality materials and strict compliance with the geometric tolerances set forth in DIN 3502. For consultation on the selection of shut-off valves and the selection of analogues corresponding to your technical specifications, you can always contact the specialists at EV Group China.
