Series LFB6080, LFB6081 2-Piece, Full Port, Lead Free* brass Ball
Valves feature 316 stainless steel balls and stems with virgin PTFE
seats and seals. The LFB6080, LFB6081’s full port orifice ensures
minimal pressure drop, while virgin PTFE stem packing seal and
thrust washer provide lasting service. The Series LFB6080 and
LFB6081 feature Lead Free* construction to comply with low lead
installation requirements.
Features
• Lead Free* brass body and adapter
• 316 stainless steel balls and stems are standard
• Virgin PTFE seats and seals are standard
• Suitable for a full range of liquids and gases
• Minimal pressure drop due to full port design
• Blowout proof pressure retaining stem
• Pressure rated at 600psi (41.4 bar) WOG non-shock; 150psi
(10.3 bar) WSP
• Virgin PTFE stem packing seal and thrust washer
• Vinyl insulator on heavy duty, zinc-plated carbon steel handles
• Fast quarter-turn open or close operation
• Excellent for throttling and balancing applications of non-abrasive
fluids where minimum flow is 20% to 100% of valve capacity
• Low operating torque
• Adjustable stem packing
• Each valve factory tested

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 pres-
sure 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).

LFB6080 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.
