Series LFBRVM1, 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
LFBRVM1 features Lead Free* construction to comply with
Lead Free* installation requirements.
These valves use a Lead Free* body full port valve design** which
includes PTFE seats and a blow out proof stem design. The relief
valve section includes a Viton
®
disc and stainless steel spring.
Features
• Easy Installation - Installs in any position
• Low profile design

For Sweat Connections Only:
This valve is designed to be soft soldered into lines without dis-
assembly, 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.
NOTICE
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.
