Installation Information
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.
*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 disassembly, using a low temperature solder to 420°F (216°C). Higher
temperature solders may damage the seat material.
