water solenoid valve

water solenoid valve

View Tameson’s selection of water solenoid valves. A water solenoid valve is designed specifically for water media applications. The valves in this category have a brass housing, an EPDM seal and are normally closed (NC). These materials are a good and reliable solution for water applications. A solenoid valve acts very quickly in comparison to other valve types. The main product specification considerations are discussed below to make an educated selection process.

Design

A solenoid valve is electrically controlled. The selection available on this page are all normally closed (NC). This means that when no power is applied, the valve is in the closed position not allowing water to flow through. When the valve is supplied the proper voltage, it opens to allow water to flow through. These valves are 2/2-way, meaning they have 1 inlet and 1 outlet. To understand how the different design types work, view our solenoid valve type difference page.

All designs are considered to be a solenoid operated water valve, but the difference in design effects function:

  1. Direct Operated: Doesn’t require a pressure differential to function properly.
  2. Indirect Operated: Requires a pressure differential (typically 0.5 bar) to function properly.
  3. Semi-Direct Operated: A pressure differential isn’t required, but assists in the operation.

Note: Proper valve orientation of inlet and outlet is important for proper function. The correct orientation is denoted with an arrow on the valve housing.

Material

The housing material and seal material are two additional specifications to consider. For water applications, you need to ensure that the housing material will not rust, contaminate the water, and can withstand the temperature range for the application. Proper seal material is important for good performance and a long service life. This category only contains our recommended materials, which are:

  1. Brass Housing: Brass is the ideal housing material for a water solenoid valve. It is resistant to water (won’t rust) and is durable.
  2. EPDM Seal Material: EPDM is the ideal seal material for a water solenoid valve. It is suitable for water, good resistance to weather influences, and suitable up to a maximum temperature of 120 °C or 130 °C.

Voltage

The voltage of the valve is dependent on what is available for the application. Typical battery operated applications will either be 12 or 24V DC, while other industrial applications will be 120, 230, or 380V AC. Available options are:

  • 12V DC
  • 24V AC
  • 24V DC
  • 120V AC
  • 230V AC
  • 380V AC

Note: A valve rated at 230VAC will work with an input voltage of 220VAC or 240VAC.

Size

This selection of valves are 2/2-way, and the inlet and outlet ports are both female. The available port sizes are:

  • ⅛ inch
  • ¼ inch
  • ⅜ inch
  • ½ inch
  • ¾ inch
  • 1 inch
  • 1-¼ inch
  • 1-½ inch
  • 2 inch

Common Water Solenoid Valve Applications

Common applications include:

  • Irrigation applications
  • Reverse osmosis (RO) systems
  • Solenoid valve for water fountains
  • Solenoid water inlet valve for a washing machine
  • Water hose solenoid valve
  • Mains water solenoid valve
  • A solenoid shut off valve for water

Frequently Asked Questions

How do water solenoid valves work?

A water solenoid valve works by being closed with no power (normally closed) and when power is applied it opens to allow the water to flow through. For closing the valve again, simply remove power.

What is a normally open solenoid water valve?

A normally open solenoid valve is open (media can flow through) when no power is applied.

What is a normally closed solenoid water valve?

A normally closed solenoid valve is closed (media can’t flow through) when no power is applied.

How much is a solenoid valve?

The two main variables regarding solenoid valve costs are material and size. A metal valve is more expensive than a plastic one. A  larger bore size results in a higher cost for the same valve specifications. View our products for our solenoid valve price range.

How to test a water solenoid valve?

If the solenoid valve does not open, opens partially, leaks, or makes a humming noise you can troubleshoot your valve to see what the issue is. For more information, read our troubleshooting guide.
