⁄4" (20mm)
Series LFBRVM1, Combination Ball Valve and Relief Valve is an
easy to install two-in-one device. Designed to be used as wa-
ter 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
• Full port ball valve with virgin PTFE seats
• Blowout proof stem

Valve shall include built-in relief protection from water pressure in
excess of 80 or 125psi. Each valve shall be full port construction**,
Lead Free* body, chrome plated brass blowout proof stainless
steel ball and stem, virgin PTFE seats, PTFE stem packing and
stem thrust bearing, Viton

relief disc and 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, requir-
ing reduced lead content. Valves shall include brass compression

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.
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.
