Solenoid Valves 1/2" | Normally Closed

What is a Solenoid Valve?

A solenoid valve is a device that controls the flow of liquids or gases. It opens and closes when it gets an electrical signal. 

King Supply offers brass and nylon solenoid valves. We carry direct and pilot-operated solenoid valves. All of these valves are hard wired. Most of our customers use these valves with our coin timers, matching the voltage of their coin timer to the proper voltage on their water solenoid valve

How They Work Together:

1. Coin Timer: This device controls how long something works based on the coins you insert. When you put in a coin, it sends a signal to start a timer.

2. Electrical Signal: When you put a coin into the coin timer, it sends an electrical signal to the solenoid valve. This signal tells the solenoid valve to open.

3. Solenoid Valve Opens: When the solenoid valve gets the signal, it opens up and lets water (or gas) flow through. For example, in a coin-operated shower, the water will start flowing.

4. Timer Runs: The coin timer keeps track of how long the valve should stay open based on the amount of money inserted.

5. Valve Closes: When the time runs out, the coin timer sends another signal to the solenoid valve to close. This stops the flow of water (or gas).

How to Connect Them:

1. Wiring: You need to connect wires from the coin timer to the solenoid valve. The coin timer will have output terminals where you can attach these wires.

2. Power Source: Make sure both the coin timer and the solenoid valve are connected to a power source. This could be the same power source, depending on their voltage requirements.

3. Control Signal: The coin timer will send a control signal to the solenoid valve. This usually involves connecting the output from the coin timer (where the signal comes out) to the input on the solenoid valve (where the signal is received).

4. Ground Connection: Ensure that there is a proper ground connection to avoid any electrical issues.

Example:

• Coin Timer: Set to allow water to flow for 5 minutes per coin.

• Solenoid Valve: Connected to the water pipe and the coin timer.

• Coin Inserted: You put a coin in.

• Signal Sent: Coin timer sends a signal to the solenoid valve.

• Valve Opens: Water flows through the shower.

• Time Elapses: After 5 minutes, the timer sends another signal.

• Valve Closes: Water flow stops.

By connecting the coin timer and the solenoid valve this way, you control the flow of water (or gas) based on the coins inserted, making it a coin-operated system.
