LFB6081**

**This valve is designed to be soft soldered into lines without dis-

assembly, using a low temperature solder 420°F (215°C). Other

solders such as 95/5 tin antimony 460°F (238°C) can be used.

However, extreme caution must be used to prevent seat damage.

Higher temperature solders will damage the seat material. ANSI

B.15.18 states that the maximum operating pressure of 50-50 sol-

der connections is 200psi (14 bar) at 100°F (38°C) and decreases

with higher temperature.

Apply heat with the flame directed AWAY from the center of the

valve body. Excessive heat can harm the seats. After soldering, the

packing nut may have to be tightened.
