Peak power drawn by solonoid valve.
Peak power drawn by solonoid valve.
(OP)
hello
considering a standard cold water pipe feeding a bath tap in a domestic house..........
-supposing a normally-closed solonoid valve was powered to fully open this cold water pipe (from initially the valve being closed)....
-what would be the typical peak electrical power drawn in actually opening the solonoid valve?
-or if you like.....how much electrical energy would be dissipated in actually opening the solonoid valve.
-also, how much power would typically be consumed by the normally-closed valve in holding the valve open?
-just general values are sort after...but more accurate if you know it.

RE: Peak power drawn by solonoid valve.
The necessary effect (or power consumption and power peaks) would principally be a combination of many factors, main beeing the pressure class rating of the solenoide valve (eg what max working pressure constructed for, but also the minimum pressure necessary by forced lifting and pilote operated valves), the construction type of the valve (from direct acting, through forced lifting (assisted by the line pressure difference) through to completely pilote operated valve) and also the quality of the construction and the actual bore (Cv) of the valve.
Note: a 1/4 inch valve may vary from fully open (6mm) -to 2mm or less.
As such all theese values would vary fairly much, and also be depending on local conditions on water nets, local currencies and solenoid (magnet construction and quality itself) and not at least DC or AC conditions.
There has also through the last 10 to 20 years (?) been a marked improvment in constructions succeding to limit the power consumption.
You could either search for details at some of the better suppliers homepages, .... See for instance
http
.. or you could give more limiting details to get a more precise answer to your question here.
Note: one of the main installment failures in solenoide valve circuits, is forgetting to protect solenoids from power peaks from the net and vice versa.
