Solenoid Valves 1/2" | Normally Closed

King Supply Company offers high-quality solenoid valves designed for use with timed shower systems, coin-operated shower timers, and other water control applications. Solenoid valves are electrically operated and allow water to flow only when activated by a signal from a timer or control switch. These valves are safe, use little power, and are compatible with multiple voltage inputs, including 115V, 220V, 12V, and 24V. Each solenoid valve system is built to handle heavy commercial use and is ideal for campgrounds, RV parks, gyms, marinas, and other high-traffic environments. Please note: solenoid valves must be wired by a licensed electrician. Required components like the solenoid valve itself, transformer (115-12VDC1000), and GFCI are sold separately.

Solenoid Valve FAQ

Below you will find some of our most commonly asked questions about our solenoid valves

What is a Solenoid Valve?

A solenoid valve is an electrically controlled valve that opens or closes the flow of water when powered. It is commonly used in timed or automated water control systems, such as coin-operated showers or push-button metered valves.

Where are Solenoid Valves used?

Solenoid valves are used in many commercial applications including campgrounds, beach showers, RV parks, public restrooms, and fitness centers. They are ideal for systems that need to control water flow electronically using a timer or controller.

What voltages are supported?

Our solenoid valves are compatible with several voltage options: 115V, 220V, 12V, and 24V. A transformer (not included) may be required depending on your power source. Most coin timers and metering systems use 12V DC solenoid valves.

Is the Solenoid Valve included with coin-operated timers?

No. Solenoid valves are sold separately. While our coin timers include the timer unit, coin mechanism, and coin box, the solenoid valve must be purchased and installed separately to complete the system.

What is included with the valve?

The solenoid valve itself includes the valve body and electronic actuator. Additional required components such as the transformer, ground fault circuit interrupter (GFCI), and any plumbing fittings are sold separately.

Do I need an electrician to install this?

Yes. All solenoid valves must be installed and wired by a licensed electrician. This ensures the valve operates safely and meets all local electrical codes.

How long can the valve stay open?

When connected to a coin or timer system, the valve can be set to stay open from as little as 5 seconds up to just over an hour. The exact timing is adjustable on the controller, not on the valve itself.

What materials are your Solenoid Valves made of?

Our solenoid valves are built from durable brass or stainless steel depending on the model. They are made for repeated use and can withstand commercial-level water pressure and flow rates.
