Is there such a thing as a 1/2" or 3/4" copper to garden hose thread adapter. The water pressure in the barn is low but volume high so I want to get restriction down. Conventional valves have way too much restriction. Thanks

You"ll have to do it in two pieces. Sweat to pipe thread, then pipe thread to hose thread. Local hardware here has the thread to thread in brass fittings.

Are you looking to back flush the water system in your barn, or are looking to put a permanent fitting to augment the water with housewater? If you want a temporary fitting to back flush the system, you could use PVC and just go to Lowes and get a couple female hose thread ends and a short piece of pipe and glue them together. Screw the fitting to the barn valve first then hose to your double ended female fitting and last the hose to the valve at the house.

For a valve can't you just use a gate valve?

A gate valve or ball valve isn't going to restrict anything. I think your talking about a "stop and waste" valve.

If you mean threaded,yes,but they're brass,not copper.
1/2 or 3/4 pipe thread to hose thread. Male or female.

Your valves aren't restricting flow until you get up into around 50 GPM. friction loss is a function of distance and your valves ave virtually no distance to them compared to the rest of the run.

Not sure what your looking for but try this
Lowes Garden hose fittings

If you can attach a fitting to the 3/4" supply and keep bends to the minimum, you can get good flow through a 1/4 turn ball valve. 3/4 Sweat copper fitting on one end and 3/4 NPT on the other, Then use a 3/4npt to Hose fitting (Lowes (below) has those). The ball valve is straight through. Jim

Right now I have a valve like this excluding the pex adapter.

I use it right now to fill a water trough in a smaller pen. It's painfully slow and I have better things to do then watch it fill. I was going to use copper but the water comes into the barn from a holding tank(low pressure) via 3/4" plastic pipe. I wanted to put a 1/4 turn ball valve in, and from the valve use copper and then a copper to hose fitting but I could just use some pipe and the right adapters. I'll see what I can find in the hardware store. Thanks for the help.

The adapter you're looking for is called a "hose bib".

Unless you're running one inch or larger pipe out to your barn, I seriously doubt the restriction is in your hydrant. Sure, you can run a larger valve and choke it down to garden hose size, but the small amount of restriction in most valves is insignificant compared to the pressure drop in the rest of the water line and the hose itself.

I ran 1 inch pipe out to my shop, about 100 feet, and terminated it with a 3/4" yard hydrant. It flows plenty of water, even more than the faucets at the house.

If its coming gravity feed in a 3/4 inch line, if I read correctly a smaller fitting isnt going to solve your problem, especially if you are wanting to increase speed of filling. Pressure and volume are interconnected as one goes up the other goes down. You can get 100 psi but may only get .1 gph flow. That doesnt help. Bigger line, more head pressure, more fall, etc. Any of those will help.
