Schneider Electric (Erie) VT3213 Valve Body

Hi may I ask what is the best way to brass this valve to a copper pipe. can I put some thinning flux paste on the pipe and free lead soldering and heat to join your valve to the pipe. right now we have a big construction project and want to get your suggestion. thanks tony 386 64 5236

Normally contractors use brazing tools with at least 5% silver rods for brass / copper or copper / copper connections. Please consult with a contractor for further advice. Thank you.
