" – 1" (20 - 25 mm)
Series LFBRV, Combination Ball Valve and Relief Valve is an easy
to install two-in-one device. Designed to be used as water heater
shutoff valves to provide both a means to shut off the water supply
to the water heater and to provide protection against excess water
pressure caused by thermal expansion.The Series LFBRV features
Lead Free* construction to comply with Lead Free* installation
requirements.
These valves use a Lead Free* copper silicon alloy body full port
valve design** which includes PTFE seats and a blow out proof
stem design. The relief valve section includes a Viton ® ball and
stainless steel spring. It is provided with a compression or PEX end
fitting to provide a secure method of connecting a discharge line.
Features
• Easy Installation - Installs in any position
• Low profile design
• Full port ball valve with virgin PTFE seats
• Blowout proof stem
• Secure drain tube connection available with PEX, Barb
or compression fitting models
Specifications
Valve shall include built-in relief protection from water pressure
in excess of 75, 80, 100, or 125psi. Each valve shall be full port
construction**, Lead Free* copper silicon alloy body, blowout proof
316 stainless steel stem, virgin PTFE seats, PTFE stem packing
and stem thrust bearing, Viton ® relief ball and 302 stainless steel
relief spring. Lead Free* combination ball valve and relief valve
shall be constructed using Lead Free* materials. Lead Free* valves
shall comply with state codes and standards, where applicable,
requiring reduced lead content. Valves shall include brass
compression nut and ferrule or PEX end connection for a drain line.

For Sweat Connections Only:
This valve is designed to be soft soldered into lines without disas-
sembly, using a low temperature solder 420°F (216°C). Other
solders such as 95/5 tin antimony 460°F (238°C) or 96/4 tin silver
430°F (221°C) can be used. However, extreme caution must be
used to prevent seat damage. Higher temperature solders will
damage the seat material. ANSI B16.18 states that the maximum
operating pressure of 50-50 solder connections is 200psi (14 bar) at
100°F (38°C) and decreases with higher temperatures.
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.
