Testing out an affordable ss solenoid.

So the story is there is a solenoid manufacture near my work. It's called STC. The solenoid model I paid was $30. It's a stainless steel unit. 4 watts consumption with 200psi max. After 8 hours of runtime, the temperature was a little warm to the touch but not extremely hot. This could be an alternative to the Burkert solenoid. So far the only thing I'm complaining is the body of the solenoid is made in circular shape. I prefer a square body like those Burkerts. I will be letting it run for the next few weeks and see how the performance go.

what exactly the design of this solenoid? internal seal same as the parker B series and burkert 6011? if it is, it is much better than the old STC solenoid that mentioned in TPT(many many years ago).

The old STC solenoids were the old block type solenoids similar to the clippard MME block type solenoids.

Here is the spec for the above model. They have 4 models that will work with our application. The one I have is 110v. I had to sacrifice my PC power cord for the assembly.


Cv=0.05
Orifice:1.2mm
Service: Air, Liquid, Oil, Water
2 Way Direct Acting
Normally Closed
Stainless Steel Solenoid Valve
Temperature: 14 -176 °F (-10 TO 80 °C)
Seal: NBR
Pressure: 0 to 200PSI;
Response Time <20msec.
Coil Power 3 to 6.5W

interested to see how this model works! I bought an STC solenoid but it was like bettatail said, very similar to the nefarious clippard solenoid and used 6watts. I read somewhere that it melted down for someone and didn't want to take the chance so i stopped using it. hopefully this one is good!

The longest time I left the solenoid on was ~24 hours. Well, It worked as expected. Like the Burkert, it got a little warm after 10-15 minutes of running. I'm getting a temperature gun to get an accurate reading. Will post more details. For the price of $30. This ss solenoid is worth it.

The melting problem is 3 - 4 years ago. Also we don't really know if it was human error or not. The company has expanded into making precision measurement tools, fittings and a new line of solenoids. I'm still hoping one day they will make a block solenoid. The only block model they have now is made of aluminum alloy. It costs $20. Maybe this model was the one melted :-).

Looks like a cross between a Parker (body) and the Clippard (electronics) - tagging along

the parkers got pretty warm but still manageable. I use mine on a reef tank where the CO2 is controlled by Apex and not running 24/7, yet

AlanLe - nice looking regulator what kind is it?

It is still up and running. I have the valve turned on 8 hours a day. It has been a week and no sign of melting or overheating on the valve.

Is this the place? http://www.stcvalve.com/
Looks like they do SS fittings too. I wonder if their shipping is cheaper than sweglok.

Nice find. Dropping $70 on the burkett wasn't exactly fun.

No that's a 10watts model. This one is 2S020-1/8A. 3 watts with 200psi working pressure. You have an option to get either 12vdc, 24vdc, or 110v.
