U.S. Solid 1/2" Stainless Steel Electric Solenoid Valve 24V DC N.C. VITON Water Air Fuel

I do industrial service work on various types of commercial and industrial production equipment, and as such, I run into machines both foreign and domestic. European machines tend to use 24 volt DC valves and sensors more than American, and finding an affordable domestic source for such things can be difficult.I got this valve for an Italian granite cutting bridge saw because the price for the OEM part was well north of $100, and the lead time was ridiculous. This valve was ~$38 and Prime eligible and looks a LOT like the original valve on the machine. Turns out, the original valve is either the same (OEMs sometimes clean the maker and part #s from parts so you have to buy from them), or a perfect copy.I put the valve on the machine and it works like a champ! My customer thinks I got the OEM and is probably expecting a high charge with my mark-up added, but I'm going to surprise him with a much lower price than he's expecting and STILL make decent money.If you buy this, one thing I will advise you to do is to check the tightness of the bolts holding the top part of the valve on. It takes a 5 mm hex key and the valve I got has loose bolts out of the box and leaked pretty good until I tightened them. Otherwise, it is a really good value for a stainless valve - especially since it is 24 VDC.

As stated this valve is not suitable for continuous operation as supplied; since it dissipates close to 20 watts. With the build up of heat; the coil in time will fail. To circumvent this issue a solenoid driver can be used. This will reduce the current by around 60% and the heat generated by around 80%. A solenoid driver turns the valve fully on for around a second than gradually reduces the current (utilizing PWM ) to a duty cycle of around 40%. An adjustable valve driver circuit board is available on EBAY that will do this for around $5. The board needs to be put into some type of enclosure. This board will greatly improve the overall reliability of this solenoid valve.I do not understand why the valve supplier does not offer this feature incorporated as part of the valve packaging since it would cost them less than a dollar!

Great product and work as great as well.

Bought the 24v to use on a constant duty 12v system works great at 12v

Works as offered. Flow will occur with very low delta P across the valve. However, draws current/eats power when on.

Trash. 2 of 4 burned out in less than a month. Replacing all 4 with something less crappy. Caveat Emptor.

Internal spring was for 15 psi far short of the advertised 125psi specification.

Works great, as it should.

Buen funcionamiento. Impresionante como funciona

散水の為に利用していますが問題なく使えています

Válvula para equipo suspendido de herbicida, vale para mil cosas más pero en mi caso para esto y genial

E un bel prodotto e il suo lavoro lo svolge molto bene lo consiglio!

No problems until now but very noisy when it switches and runs quite hot.
