Shut off valve?

[boshuter]

Not even sure it's called a shut off valve; what I'm looking for is the valve that can be installed in the line after the condenser so you can pump the charge into the condenser to be able to adjust cap tube length without evacuating the whole system.

If anyone has a link or something where I can find these it would sure be appreciated

2 way and 3 way service valves.http://www.wilspec.com/products/lite..._valves_SV.pdf

Some packless ones on ebay atm!

if u put one before the condenser it is great for recovering gas into a cylinder. and then u can adjust the captube vacumme and recharge with the same gas.

You would need one on the evap side too right? One on each side of the captube.

technicaly, no, as the reed valve in the compressor would keep it in the condencer.

Ya reckon?

Your assuming the compressor has a reed valve.
And even if it did, your a fool to rely on it holding the entire gas charge back.

Yes you will need two valves, one either side of the cap tube.
Same as pumping down a heatpump. Close off liquid valve, wait until low side reaches a near vacume, then close suction valve. And then turn power off of course.

fine, recip compressors, and for the short time, no you needn't be a fool it hold just fine on short term, and if it dosn't your compressors garbage.

Assuming, no, last time I check a recip they're kinda the defacto mod operandi in the system, but then again that's in my reality, yours may yield different results.

IMO that wound be best for captube swap if that was all you were changing.
Or run one on suction as well at the evap to be able to change captube and or evap. for testing. I'm using flair fittings just for speed.

Why not let the condensor do it's job and recover the liquid after the condensor.

I have been saying since I came here to put a shut off before the cap tube so you can pump most of the refrigerant into the condensor.Then you just need to vacuum the low side after the change.

Thats exactly what I plan to do...... see... I listen

I been here 2-1/2 years

Boy it sure seems longer,you guys are surely giving me ulcers


Forgot; Refrigeration Ball valves unless a electric solenoid valve is used.500 psi rating.

If you put the hand valve right after the high side access valve, the compressor pumps the gas into the recovery tank no need for a recovery machine . (only for greener gasses r290 ,care etc..)
