Watts LF7 3/8 - Part of the LF7 Series
This 3/8 inch dual check valve backflow preventer helps prevent the reverse flow of polluted water from entering into the drinking water supply at the service entrance or at individual outlets. It is designed for in-line continuous pressure applications, such as wash-down sinks or other installations, where a hose type device connected to the domestic water supply can be submerged into a non-potable liquid. It consists of a lead free cast copper silicon alloy body, 3/8 union NPT thread female inlet by NPT thread female outlet, two plastic replaceable check valves, Buna-N seals, silicone discs, and stainless steel springs. The minimum working pressure is 10 psi (69 kPa) and the maximum working pressure is 150 psi (10 bar).
Features- Can be installed vertically or horizontally
- No special tools are required for servicing
- Temperature range is 33 to 180 degrees F (0.5 to 82 degrees C) continuous
- Short lay length
