Description
Watts® Series LF757DCDA and LF757NDCDA Lead Free® Double Check Detector Assemblies are designed to prevent backflow of non-health-hazard substances into the potable water supply. They provide protection against both backpressure and backsiphonage and are primarily used in fire sprinkler and fire protection systems where monitoring of unauthorised water usage is required.
These assemblies feature compact 304 stainless steel housings with two independently operating tri-link check valves, two shutoff valves and four test cocks. The unique tri-link spring check design provides low pressure loss, while the lightweight construction is approximately 70% lighter than traditional designs for easier installation and servicing.
The LF757 series can be installed in horizontal, vertical or N-pattern configurations and has a maximum working pressure of 175 psi (12.06 bar). Contact Watercare Products for Watts LF757DCDA / LF757NDCDA selection and quotation in Singapore.
