How do I solve water hammer with solenoid valves?

 Water hammer at solenoid valves or solenoid valve

 "The pipe pops off the wall"

 The bang in the pipe, (kinetic energy) what is called water hammer, you do not hear if the water pressure and water speed meets the NL guidelines for water pipes. In other words, the construction must have been installed according to Dutch NEN installation technology.

 A frequently asked question is; How can water hammer be remedied? A valve or solenoid valve is not the cause of water hammer when the speed of the water and / or pipe diameters are correct. Larger diameters gives less speed and less water hammer.

 In general, indirect valves close more slowly and are better than direct-acting or zero-bar valves. It is about how and how quickly the valves close. A water hammer free valve contains an acceptable closing time with a water supply network, which causes no problems.

 The B205DEZ series can be a good choice for your solenoid valve.

 Advice:

With existing pipeline network with problems:

• install water hammer damper (s)

• use slow-closing taps

With water valve:

• relocate the membrane

• use motor-controlled crane

• test regulations for pipeline network i.v.m. pressure and speed

• increase infrastructure of the pipeline network

• reduce flow capacity by using flow or flow limiters.

The above is a very simple explanation of water hammer and the origin of this phenomenon.
