Electrically-operated solenoid valves, plumbing water solenoid control valves guide:

This article describes and illustrate the different types of electrically-operated or solenoid valves found on water supply and drainage systems as well on other plumbing and heating devices & fixtures.

We discuss where to buy a solenoid valve, provide a list of solenoid valve manufacturers, brands types and we explain how to choose the right solenoid valve for water or other controls in a building. Details about all types of plumbing system valves on supply piping, drain piping, & plumbing fixtures or appliances: check valves, flushometer valves, etc.

This list of the types of control valves found in residential and light commercial buildings includes links to detailed information about each valve type.

Electric Solenoid Operated Gas, Oil, Water Valves used in Buildings

Alcon low voltage operated solenoid valve (C) InspectApedia, Alcon contact information is in this articleHere we describe electrically operated plumbing valves used for water control of equipment or piping in buildings. Solenoid valves are electrically controlled valves that in response to an electrical signal can open, close, or adjust the flow rate of a liquid or gas being piped through the valve.

How a solenoid valve works:

An electrical current in any of a variety of voltage and cycle ranges (depending on the valve design) is converted in the valve to an electromagnetic field by applying the current to a coil (coiled wire around a core). The magnetic field created by the current in turn is converted to mechanical energy to move the valve to the desired position.

Solenoid valves are used in heating and cooling applications as well as in many building water supply applications.

Reader Question: where can I buy a solenoid-operated water shut-off valve?

15 January 2015 Martin said:

We have a water break tank in basement cant get overflow out.We have been told we can drop a over flow from the large tank into a smaller header tank.

A flow detector is then place in the smaller tank and then connected to the incoming water main via a solenoid valve which would turn off water supply.

Any ideas where I can purchase solenoid-operated water shut-off valves?

This question and our reply were posted originally at WATER TANK: USES, TROUBLESHOOTING.

Reply:

Martin a number of companies provide electrically-operated solenoid-type shutoff valves including valves that can close off a water supply line. The operating pressure range and piping diameters among the various products vary so you’ll want to contact the company’s technical or sales people to discuss your specific needs.

Prices for electric solenoid valves range from under $50. U.S.D. to over $500. U.S.D. depending on the application.

Watch out: check the solenoid valve specifications carefully to match against your system's needs, including at least the following:

  1. Suitability for handling the liquid you are controlling
  2. Operating pressure range of the solenoid water valve
  3. Operating voltage ranges of the solenoid valve: for example low-voltage 12VAC, 12VDC, 18VAC, 24VAC, or household current levels of 120VAC 50/60Hz to 208-240VAC 50.60 Hz
  4. Valve default position: normally OPEN or normally CLOSED
  5. Use of lead in the valve components - may be unsuitable for some locations or may be prohibited by local plumbing codes
