About this item

  • Constructed of industrial grade brass, this valve is corrosion resistant, more conducive for welding, optimal for higher temperature projects, and can be used with gasoline, diesel fuel, kerosene oil, natural gas, air etc. Due to the chemical composition of brass, this valve should NOT be used with projects involving drinking water or other water projects.
  • This valve was manufactured with a VITON seal. VITON is the most durable and high performance rubber material with the ability to resist high temperatures and corrosive chemicals and other fluids like gasoline, diesel fuel, oils, and lubricants.
  • This highly responsive valve will open and close in less than 1 second when actuated; meaning it will open or close the flow instantaneously when energized or de-energized. Also, our U.S. SOLID engineers have determined that the life cycle of this valve is well over a million cycles with proper operating conditions and maintenance.
  • PLEASE NOTE: This valve is NOT a continuous duty valve and should NOT be in continuous use for more than 8 hours in a single cycle; to do so will shorten the life of the valve and may cause the core of the valve to burn out. If you need a continuous duty valve for your project please search for our U.S. SOLID Motorized Ball Valves.
  • As with all U.S. SOLID products, this valve comes with a ONE YEAR WARRANTY. If the valve does become defective within the first year of purchase, U.S. SOLID will gladly replace it.


Product Description

U.S. Solid 1/4" 24V AC Normally Closed Solenoid Valve, VITON gasket, Solid Brass

1

The U.S. Solid electric solenoid valve features a durable brass body, suitable for outdoor but not underwater use. It's favored by customers for DIY projects, moderate temperature and chemical applications, as well as for controlling flow in irrigation, reverse osmosis, and motorcycle systems.

Direction of the Flow

Most U.S. Solid Valves are UNIDIRECTIONAL

Make a note of the arrow on your valve. Most U.S. Solid valves are unidirectional. This means they are intended to flow in one direction only, in the direction of the arrow. If connected in opposite directions, the valve will not actuate properly (will not close for Normally Closed valves). Additionally, be sure the medium passing through is filtered. If not, particles will cling to the gasket over time, which can cause it to not seal properly.

THREADING

U.S. Solid Valves follow National Standards for pipe thread. We suggest the use of Teflon tape to ensure the seal of the NPT threading. The tapered male and female thread form angled surfaces that with increased torque squeeze the Teflon tape resulting in a tight seal.

OVERHEATING

These valves should be energized for less than 8 hours. While most do not have more than 18W of power, the coils are in a contained area and can burn out if energized for too long. We suggest a computer fan to keep the coil cool if necessary to energize continuously for extended periods.

POLARITY

  • For valves with 2 wires, the valve will actuate regardless of which terminal each wire is connected to (+ or -). Some units include a ground wire. Open up the connector and look for the ground symbol (as shown in the corner).
  • For valves with a ground wire, please be sure to ground the valve.
123

GASOLINE and PRESSURE WARNING

  • NBR gaskets should not be used with gasoline, kerosene, or other petroleum products. If your valve requires contact with these substances, opt for one with a VITON gasket.
  • All solenoid valves need some pressure to actuate. This is especially true of pilot or indirectly operated valves.

When the solenoid on my humidifier stopper working, I needed a new one. The replacement part was too pricey, so I choose this one. While the install was not a perfect fit, it was close enough to be serviceable, and has worked well since.

This product is very well made and it's an excellent valve. Great Electric Solenoid Valve 24VAC . This product is very well made and it's an excellent valve. I currently use this product for my 24 VAC water misting system.

used to turn on/off the flow to the pre-cooler misting system for my air conditioner. i tapped into the 24 vac circuit to the starter solenoid for ac compressor, so the switching is already there.

I fit this to my humidifier as the old valve went bad again. Thought I'd try this one. Decent 24v valve. Have to see how long it lasts. Decent for the price.

I have moved this solenoid back and forth between my Heat Pump condenser and my interior humidifier. The Heat Pump location got water in it...do I don't blame it.

A well made product at a fraction of the price of other name brand valves of this type and size. I have purchased other sizes of this product and found them all to be of high quality.

Compre 4 válvulas con un funcionamiento Maximo de 10min al día y a los 3 días dejaron de funcionar, se quedaban siempre abiertas, no volvían a su estado de reposo.

Spedizione in due giorni. Presa una da montare su una tromba ad aria, sbadatamente presa da 24v, l'ho restituita e ho preso una da 12v Della stessa marca. Ma comunque la qualità rimane ottima , non c'è altro da dire, funziona come dovrebbe, e come qualità prezzo mi sembra più che giusto. Lo consiglio

Montata su un riunito odontoiatrico e funziona perfettamente.Meglio dell'originale che costa 10 volte di più.

Il dispositivo si presenta come in descrizione, robusto e facide da installare grazie ai due fori felattati posti nella parte inferiore.Impiegato per irrigazioni piate con acqua in caduta ( non in pressione acquedotto).
