Brazing Procedures for DanfossSolenoid Valves• Danfoss stainless steel solenoid valves require aslightly different brazing technique than brassbodiedvalves. Copper clad stainless steel does not require asmuch flame contact as copper tubing. Apply heat to the copper tubing first then thesolenoid socket.• 15% silver solder is recommended although silverbearing solder in the 5% to 55% range can beused.1. Remove coil and verify direction of flow.DIRECTION OFFLOW ARROWSV30692. Fit valve in place and align stem at the 12:00position.90° 90°3. Do not disassemble valve.SV3070Part Number 80-01111-9 7/10 197
