I may need two of the above, ideally pneumaticly controlled. Any suggestions where I can get them and what sort of £ would we be looking at?

If it is for milk or similar, you need to avoid ball valves as there will be a dead zone that cannot be cleaned with CIP. Look for something like a pasteuriser divert valve, lots of pictures online but no UK supplier comes up. I would go to Colsan, Moody, Machinery World or similar second hand pasteuriser suppliers for this type of application.

We get stainless bits from this ( local to use) company. Valves can be supplied with pneumatic actuators. Sit down when you get the price. .
As well as Steven's suggestions another company to try is Harry Travis in Yorkshire

he would possibly even have some suitable 2nd hand ones, depending on what they are needed for.
Can also s/s pipe weld to order and save a lot of hassle with fittings if you know exactly what you are wanting.

Thanks all. We want to put a valve in our milk line so that we can divert transition milk from our dump cows (at the end of milking) into an alternative tank for feeding calves. Any advice? It is essential that whatever we use an be washed in situ at no detriment to our milk hygiene.

Difficult to advise without knowing your current setup & how much extra pipe is involved with your calf milk line

Actually only a few metres. Currently the line runs past our calf room and we have a short length of flexible pipe which is disconnected at one end and dropped into the tank. In future the idea is to relocate the tank just outside the calf room and replace the flexible pipe with a permanent length of Stainless Steel but add a three way valve so we can either divert the milk to the calf tank or to the main bulk tank. Naturally for the majority of the time it will just sit in the bulk tank "position". We are batch calvers so we have a sizeable "dump group" for a short period of time. The calf tank "spur" would be just 2 or 3 of metres max. We could include a "return" to the main line so it could also be washed in situ but this might be overkill as we could just manually flush through some water from our steam cleaner daily. Just wouldn't want the additional three way valve to cause any problems in washing the main line?

 

[frederick]

Making it automatic seems mad to me. You are going to have four milkings of good milk in your main tank and then rely on someone flicking a switch and working that is then going to stop sending milk that will make the rest of it unsaleable.

If it's not that far is it not better to put a return line in that the pipe can be taken off the front of the tank and connected to. This will avoid the washing problem as well.

 

[sjt01]

Although agreeing with @frederick 's point above, if you want something simple, use a pair of these vacuum operated pinch valves, one on each branch of the tee. This one is to bypass our plate cooler when draining down milk.

3 way valve will be an expensive way of doing what is essentially a simple task.
Your milk line into the tank ;
bottom or top fill?

 

[PREES]

Into the bulk tank - bottom fill, into the calf tank top fill. The milk line runs at about 8ft above floor level and drops down in the bulk tank room.

 

[upnortheast]

I guess the key is to make it "idiot proof". to remove the risk of contamination of the bulk tank.

Lely use a 3 way valve on the bottom fill to send wash water onwards. ( or in our case sending the milk to the bottling plant holding tank. - but its controlled by the technology

When you finish milking do you remove pipe to connect to a wash return line?
could Flexi off the wash line run to the calf tank?
that way, everything will still be cleaned in situ

That's exactly what we do now but because the line is so high we have to use a ladder to access it and we wanted to do without the length of flexing pipe if possible.

sounds like all you need to do then is carry on using the wash line return and put a simple 3 way valve in it to drop short pipe into the calf tank which you could clean manually, or again set up a 2nd wash line return to flush through.
It could also be achieved very cheaply by installing 2 x butterfly valves to make the diversion from the wash line manually, which would then be easy to wash also,

Depends on the definition of "cheaply "
New 50 mm stainless butterfly valve will be around £150 then need suitable fitting either side. May be s/h ones about

Don't p*ss about with 3 way taps, -they are expensive, simpletons will turn them the wrong way and how are you going to wash the line??
Better to extend (or break into) milk delivery line. Just couple together when not using calf tank. That way every milk line is washed at every wash.

 

[Sparkymark]

The 3 way valve i just installed to switch between the main tank and the buffer tank.
Obviously not connected yet, but milk goes in from the bottom and goes left or right to the tanks.

Very smart. However, can see straight away that the hosetail ends are threaded in. These will definitely need dismantling and cleaning manually on a regular basis.
Out of interest, was this valve sold to you as a "food/dairy grade " valve?
