It's a very good drawing of a piloted valve and a very good explanation of principles of operation. I didn't understand how piloted solenoid valves work until I read it. However, piloted solenoid valve is not the most basic kind of solenoid valve, even though it could be the most ubiquitous kind. Write-up for the basic kind is in progress.
I think the description is lacking an important fact: it's not mainly the spring that is keeping the valve closed, but the fact that the C side area of the membrane is larger than the input side, hence a net downwards force from the pressure! — Preceding unsigned comment added by 93.97.72.81 (talk) 23:31, 21 November 2011 (UTC)
Operation description[edit]
The section confuses force and pressure. The argument is hydrostatic and ignores dynamics; the column of water must be accelerated at the diaphram. The spring is minimized. The schematic has an extraneous valve seat. Glrx (talk) 17:40, 8 February 2013 (UTC)
When the valve is closed the pressure on both sides of the diaphragm is the same and the force on the upper side is greater due to the greater area. Pretty simple really. The explanation requires no dynamics analysis for the concept to work. The second valve seat is not required for the concept to work but in practice many valves do have it, even though not strictly necessary. 83.60.113.87 (talk) 19:17, 29 March 2013 (UTC)
External links section[edit]
I'm not really sure why we have an external link to http://www.maritime.org/doc/fleetsub/refrig/chap7.htm. Yes it is an example, but does it add anything useful? --Tony Wills (talk) 09:08, 3 April 2024 (UTC)
