How to solder high pressure ball valves
High pressure ball valves are generally used in plumbing. They are installed in the cold and war water copper lines so if you have do a repair work like changing the faucets on a sink or taking out a sink to put a fresh one in, you do not have to turn off the water to the full home. You just turn off the ball control device on the water lines leading to the job project. The handle of the valve is linked to an internal ball that has hole running via it. When the valve is the unlock place the hole in the ball is lined up with the opening in the copper pies on either side of it. When the high pressure ball valve is the closed place the holes disappear from in front of pipe openings no water can run through. Soldering in a high pressure ball valve is not different from soldering a normal copper united. Here is tutorial on solder in a high pressure ball valve on a fresh copper water pipe installation,kp-lok.com.
Dry fit the piping and copper on either ball valve side. Put the pipe copper out and dirt-free it.
Apply Emory paper to smooth the exterior of the copper pipe until it is shiny and bright looking. Force a wire-fitting brush into both finish of the high pressure ball valve and twist it around to clean the within of the copper tubing of the control device.
Brush paste flux on the exterior of the copper pipe and the within of both ends of the high pressure ball valve.
Force the pipe copper ends into the high pressure ball valve. Before beginning to solder ensure the ball control device is in the open place.
This means the grip of the high pressure ball valve is parallel to the copper pipe.
Light the propane torch. Grip a spool of wire solder in the non-leading hand.
Begin warming up the copper pipe where it enters the high pressure ball valve one just one side. Watch the flux.
When it turns gooey and brown in look and begins to bubble the metal is getting warm enough for the solder to flow. Touch the tip of the wire solder to the steam and watch for it to melt and flow fully around the seam.
When the high pressure ball valve and copper pipe have cooled fully, take a paper towel and cover it in the region of the pipe where it meets the control device and rub dynamically to dirt-free the surplus flux off the pipe. Perform this on both valve sides. If you do not clean off this flux, the acid in it will eventually eat via the copper an d make a leak in the pipe.
Do not forget to unlock the valve before starting to solder. If you do not you will damage the internal seal on a brand new high pressure ball valve. You will have to unsolder it and throw it away.
