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.
