Specifications

A 2-piece full port Lead Free* brass ball valve to be installed as

indicated on the plans. The valve must have a blowout proof pressure retaining 316 stainless steel stem, 316 stainless steel ball, virgin PTFE seats, seals, stem packing seal and thrust washer.

Valve must have adjustable packing. Valves with O-ring stem seal only are not acceptable. Pressure rating no less than 600psi (41.4 bar) WOG non-shock, 150psi (10.3 bar) WSP. The valve body and

adapter shall be constructed using Lead Free* brass. Lead Free* ball valves shall comply with state codes and standards, where applicable, requiring reduced lead content. Valve shall be manu-

factured to the MSS-SP-110 standard and shall be a Watts Series LFB6080 (threaded) or LFB6081 (solder).

Pressure — Temperature

Temperature Range: 0°F - 350°F (-18°C – 177°C) @ 50psi (3.5 bar) Maximum Working Pressure: 600psi (41 bar) WOG non-shock;

150psi (10 bar) WSP

**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 solder 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.

*The wetted surface of this product contacted by consumable water contains less than 0.25% of lead by weight.
