LEAD FREE
*
*The wetted surface of this product contacted by consumable
water contains less than 0.25% of lead by weight.
**This valve is designed to be soft soldered into lines without dis-
assembly, using a low temperature solder (420°F/216°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.16.18 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 temperatures.
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.
