Series B6080, B6081
2-Piece, Full Port,
Bronze Ball Valves
Sizes: 1⁄2" – 2" (15 – 50mm)
Series B6080, B6081 2-Piece, Full Port, Bronze Ball Valves
feature virgin PTFE seats and seals. The B6080, B6081’s full
port orifice ensures minimal pressure drop, while virgin PTFE
stem packing seal, thrust washer and chrome plated brass ball
provide lasting service.
Features
• 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 bar) WOG non-shock; 150psi
(10 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 nonabrasive 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 bronze ball valve to be installed as indicated
on the plans. The valve must have a blowout proof pressure
retaining stem, chrome plated brass ball, virgin PTFE seats,
seals, stem packing seal and thrust washer. Valve must have
adjustable packing. Valves with O-ring stem seal only is not
acceptable. Pressure rating no less than 600psi (41 bar) WOG
non-shock, 150psi (10 bar) WSP. Valve shall be manufactured
to the MSS-SP-110 standard and shall be a Watts Regulator
Company Series B6080 (threaded) or B6081 (solder).

**This valve is designed to be soft soldered into lines without disassembly, 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.
