Description
Watts® Series LF919 Reduced Pressure Zone Backflow Preventers are designed to protect potable water supplies against contamination caused by backpressure and backsiphonage in high-hazard cross-connections.
The LF919 features two poppet-style check valves, replaceable check seats and an intermediate relief valve. Its compact modular construction and separate access covers provide convenient access to the check valves and relief valve for easier inspection and maintenance.
Lead Free® construction makes the LF919 suitable for potable water installations, while chlorine-resistant elastomers and replaceable push-in check valve and relief valve seats help provide reliable long-term operation.
The Series LF919 is suitable for commercial, industrial and other potable water systems requiring reduced pressure zone backflow protection. A flood sensor is also available to detect excessive discharge from the relief valve. Contact Watercare Products for Watts LF919 selection, technical assistance and quotation in Singapore.
