Duda Diesel2WJ20020N:110v 20 mm 3/4" NPT Normally Closed Stainless Steel Viton 2-Way Solenoid Valve, NPT Female Connector, Stainless Steel

I bought a couple of these units to demonstrate, prototyping of a patentable work on energy conservation in hot water systems for multiunit buildings.I Selected this unit since it directly energizes and remotely controllable from normal voltage supply.The unit functioned per expected design with easy water flow.Installation is relatively simple. Take particular care to use adequate plumbing tapes around threads to prevent any fluid leaks.It needed tightening on a vise rather then in-situ. The opening for electrical wires is somewhat constricted to connect three wires( Green,Black and white wires). As a result I had to make the green ground connection to external nut that holds the coil.I could use a three way control valve for this project( the same gate of the valve that closes one port while opening the other port) that could be cost effective, more reliable and less power consumption instead of using two separate valves.(such design available but for very small diameter sizes intended for medical applications)No one makes one for 3/4" size. The alternate solution was to use two valves( one normally closed, the second one normally open type), cost ineffective, less reliable, and more power consuming solution. Manufacturers, please, take note for new product offering for bigger orifice sizes.The product was delivered well ahead of time of the quoted date. Excellent service at a competitive cost.

I used this product inline with a marine toilet system on my boat that had it's water supply several feet above the toilet which caused it to slowly flood. Since this was when I was installing it I knew I needed some sort of solenoid inline. The local major marine stores had plastic ones that were a bit smaller but cost $110 each and were made out of plastic, and my first search online found a similar unit to that one for a mere $7.50. Opting for a better material than plastic I went on the hunt for something made of brass, steel, or whatever when I came across these. They're WAY overbuilt for what I needed but you know what? For the price tag why complain? After installing it they worked perfectly until... I noticed that the toilet was slowly filling again. Fortunately this unit has just 4 bolts to undo and I found the issue, a chunk of plastic from my water tanks had worked its way down to this solenoid and got stuck thus stopping the solenoid from sealing properly. So in about 10min I had solved the issue 100%.So ya. If you NEED a solenoid or ANY solenoid I HIGHLY recommend this or any from this sellers store.

I purchased this valve to work with an on demand pump for a ag sprayer that I built for my tractor. I ran a separate power feed for the pump direct and then ran the supply for this valve through a switch in the cab of my tractor.It worked perfect very quick response time both open and closed. The pump that I use has a max pressure of 60 psi and there is no bleed through.I have only had it completed for about a week and used it twice. I will update after a while as to the durability.It shipped very quickly and came in before the estimated delivery date by a couple of days.Very happy with this valve.

Used 3/4 STAINESS on 5-10 psig STEAM line. Has been functioning well for about 1 month now. Note that stainless have a higher temperature rating online (250 vs 180 F I think)Update: 2 months. Installed another to replace a pricer valve.Update: 5 months. Diaphragm failed. VITON is not compatible with the corrosion-inhibiting amines in industrial steam. Need EPDM seal. I'll be looking around...

Fast delivery easy to understand instruction..Used these for a propane and oxy cut off with a bypass on the oxygen side for my flameworking torch.. it was easy to wire up and plumb together to make yourself a decent pedal for your two stage torch without breaking rhe

no matter what i did there was a slow dripping leak out of one of the ends due to a poor threading job. but i use it for my RODI filter on my fish tank so i just positioned it over my reservoir bucket. It evaporates out of the tank faster than this leaks so its ok. but if i were to use it anywhere else it would have been unacceptable. easy to use though. gets kinda hot after on for an hour..

We use these for steam lines and they work great. With constant industrial use, they last us 4-5 years. As good or better than valves that cost twice as much.

There are all kinds of different solenoid valves and I looked all over even Grainger but could not find a suitable one for my application. I want to control water in RV tanks with 12VDC. Some of the lines are pressurized and need a continuous duty valve. Some of the lines are gravity drain outs and need a large orifice non-pressure flow so the tank would fully empty out. This high quality product works great for both.
