Using Electrical Valves in a Filling Machine?

Your not going to get a lot of answer with a question like that. I think we would need more info. What are you filling gas, liquid, air? What type of valve? Electric doesn't tell us crap.

hey.. sorry for this min info

well.. wht i want to do a system that makes sth like cookies (but it has other name i dont think that everybody will know then name).

so am usin in this sys is an iron pieces over a conveyor belt moves a round while this valve is workin to pump the LIQUID over them then go to van.

i made the design for the proccess and its electrical components, but wht i need is an electrical valve (this is the type of the valve) with 3/8 inch ... so my question is how can i implement it in the proccess??

I am not exactly sure what you want but I expect you are looking for a solenoid valve. Read this about them;

http://en.wikipedia.org/wiki/Solenoid_valve

If that is what you want then there are plenty of manufacturers to choose from. Try looking at the GlobalSpec site link on this page and look for a manufacturer close to your location.

hey... first i want to say thanks ed and masu for tryin to help...

Masu... yeah this is wht am talkin about (another name), well it actually in on/off valve, it looks like a switch but in a valve model...

lets say that this graph is the sys (i tried to make as fast as i can, so soryy).

1-is apiston 2- motor
3-tank filled with fluid 4- electrical (selonoid) valve
5-conveyor

so wht i need to do is..
movig this piston counter clockwise or clockwise to move the piston up and down to push the fluid into the selonoid (instead of whole hydraulic sys).
then, open the valve..
then to the conveyor...

hopefully u got my point...

so wht am askin for is:
1) wht recommended type of motors should i use to the conveyor and the piston?
2) how can I operate with these types of selonoids in an electrical circuits?

thanx

Keep going w/the details!

Conveyor ?'s :

How long ?

How wide ?

How much weight?

Valve ?'s :

viscosity of material to be metered?

Rate of application ?

Cycle time ?

Pressure of system?

The drawing you provided sort of looks like a stepper motor w/a piston & connecting rod.

You could also use screw conveyor & vary the speed of the motor for continuious dispensing.

????

more clarity please, will you need to syncronize the valve w/the product?

How will this be done?

photoeye?

encoder?

prox?

mechanical linkage or chain & sprocket connected to the conveyor?

I'll include a short story

Many years ago the Spanish sailed into the Gulf of Mexico & landed

they asked the natives [Maya] what they called their land

Yucatan was all the natives responded with

they moved down the coast & repeated the process

Yucatan Yucatan Yucantan Yucatan, always the same

In the Maya language Yucatan means " we don't understand you "

Yucatan Dude!

You appear to be asking for a solenoid pump, not a valve.

The solenoid driving your piston must be sized for the volume & viscosity
of the fluid you intend to move & the speed at which the operation must
occur.

A spring could 'reset/recharge` the mechanism if the viscosity/speed
factor is not too high. It is cheaper than a two way solenoid.

Cooling of the solenoid coil could be a factor.

I suggest that simple one way valves could be used to control both
the nozzle and intake feeds.

Hi Meedo433q, I had a look at your drawing and from it I gathered that the substance you are trying to control is fairly thick. This means you wont be able to use an ordinary valve, check the diagram below out.

As you can see in the top valve the path through the valve isn't straight and if the fluid you are trying to push through it is too thick the valve will not be able to close properly and the whole thing will clog up. For your application I suggest you use a ball valve like the lower ones in the diagram. As you can see the flow is straight through when it open. This type of valve will also be considerably easier to clean. A plug valve works in a similar way to a ball valve except it uses a slightly tapered cylindrical plug instead of a ball. Finally you may be able to use a knife valve. A knife valve uses a knife shaped plunger to interrupt the flow but will require more force to operate than a plug or ball valve.

hey guys.. thanx for care...

the conveyor and its specicfications doent matter cuz there are a plenty of them i can choose, the substance which i wanna use called "qatayef" (have u heard about it Grath? i dont think so ;-) )..

anyway, wht i need is the valve which i think ill take the ball valve (thanx Masu), cuz the material has a mount of viscosity.. and other measurments are still under constructions, am still gathering info so i can use the optimam solutions

its a cooking machine for a food in east asia, so i appereciate any help in this mashine...

thanx everybody...

Hey made me look it up.

Basicaly stuffed pancakes

does that mean you are going to be dispensing the "batter" or the stuffing ?

seems like you are talking about cooking them on cookie sheets running down a conveyor.

You should look into commercial baking equipment, to avoid "reinventing the wheel"

LOL

hey..

the diffrence that pancakes has to be cokked at the both sides but wht am talkin about is one side cookin.. do u get my point??

so the viscosity and the density will be the most important issues to choose the valve...

yeah the oven will be under the conveyor.. and yeah i did it and went to bakers to see the machines.. lol ;-)

Nope

what is the point ?

cooking on 1 side just makes it an easier process, transferring or any kind of manipulation, is when the waste happens.

the link is a picture of a hand operated device, that looks alot like your drawing.

the valve it self is a needle valve, the batter flowing over the needle & then forming a nice round stream when the batter hits the hot griddle.

the way the batter hits is going to determine the shape of the finished product.

adapting something that already exists is always easier!

its medo433q who send the reply a bove... sorry ;-)
