Series LFBRV

Combination Ball Valve and Relief Valve

Sizes: 3⁄4" – 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 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 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. Valve shall be IAPMO listed. Valve shall be a Watts Series LFBRV.

** PEX end connections reduce full port to reduced

port dimensions.

NOTICE

For Sweat Connections Only:

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