Is this the factory A/C expansion valve for my 1964 with factory C60?

[Claus S.]

I just cleaned an old expansion valve that came with the outer AC evaporator box to check if can use it

On one side from top to bottom it says D72
226
14
B2
<------ There is also an arrow pointing showing the water flow

The other side it says CCA 222.
Any here know if this is the correct valve for my 1964 or is it an replacement valve?

The only thing i can say is that i can blow air thru the valve without any problems but i do not know if that is the how the valve should be when it is not hooked up to anything

Here is a picture showing the letters, digits on the valve

Compared to the replacement valve i bought the capillary tube is shorter on the valve shown in the pictures

With the long tube, it is the same as the current service replacement. Original did not have a capillary tube long enough to coil as yours is

The valve did not have any coils on it when it was on the box i recived it. I coiled it up to make place for it in a box i have
The capillary tube on the expansion valve in the pictures is much shorter than the one on the replacement valve i bought
But as you say this is probably a replacement as well

Claus -- here's the original, still on my early '65. Notice the coiling around the tube at the head. I think this is to provide protection against bending at this location.

The A_8_4 stamping might (if a date) be August 1964, as the car is a 51014xx VIN.

That is quite a big difference from the one i thought have and that i thought might be original.
Both tubes on the repro one i just bought and the one i asked about here have the location of the tubes identical so that is a give away for not original compared to the one you have Wayne
The coiling around the tube at the head is different that on the 2 repro valves i have,
Also the lower tube on your original 65 valve is different since the tube goes out from the "hat"(top)on the valve
Is the original valve made of aluminum and not brass?
Thinking that you valve looks more aluminum colored?
It is very easy too tell the difference when looking at the the picture of my repro valve to the left and Waynes valve original to the right

Here is the one I got off a 65 to replace the one from my 63 that is stuck closed.

Thanks I see that it says Frigidaire on the valve you have Harry


Any here ever seen the inner AC heather box that Long Island Corvette Supply sells?
I would like to know if the reproduced AC heather box is as good as the original ones

I need a new reproduced inner AC heather box or an original one in good condition

I have not seen the LIC box. There was one for sale at the Florida Regional with the STV attached for $500.00. I did not inspect it I just asked the price. I can not recall the seller.

Re: Is this the factory A/C expansion valve for my 1964 with factory C60?

Harry you must be thinking of the outer AC evaporator box since it had the STV valve attached
The outer AC evaporator box is not being reproduced so the only way to get hold of one of those is to buy an original AC evaporator box
It is the inner AC heather box placed behind/under the dash that they reproduce

I have a original expansion valve from a 1963 by the way here. But there is only one thing and that is that some have gut the tubes off of the valve as you can see on the picture below
I suppose that is not worh trying to restore if any can?

I read your post too quickly, sorry. And yes I agree it would fruitless to try to fix it. Look for a working original.

Re: Is this the factory A/C expansion valve for my 1964 with factory C60?

I think i found the original correct expansion valve even if it says it is for an old Caddilac
Have a look at the picture

If the capillary tubes are long enough you should be fine.

Re: Is this the factory A/C expansion valve for my 1964 with factory C60?

Claus -- your picture looks appropriate, as Larry says, if the capillary tube is long enough. I just did a rough measure on my early '65 from where it exits the head of the expansion valve (with the spiral armour) to where it disappears under that black insulation "gunk" that surrounds the clamp (dark green) that holds the power element bulb against the outlet pipe of the evaporator. I feel the start of the clamp, but can't feel the bulb itself, so it could be another inch or so under the "stuff".

Re: Is this the factory A/C expansion valve for my 1964 with factory C60?

If i buy it, i will buy from looking at the pictures and just hope that the capillary tube is long enough

Re: Is this the factory A/C expansion valve for my 1964 with factory C60?

Here are a couple pictures from my '63. One without the STV shows how the tube was originally routed. The other is after restoration. Hope these help.
