Description
Watts® Series 757DCDA and 757NDCDA 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.
The compact stainless steel housing incorporates two independently operating tri-link check valves, two shutoff valves and four test cocks. The patented tri-link spring check design provides low pressure loss, while the lightweight construction offers easier installation and servicing compared with traditional designs.
The Series 757 is suitable for horizontal, vertical or N-pattern installations and has a maximum working pressure of 175 psi (12.06 bar). Contact Watercare Products for Watts 757DCDA / 757NDCDA product selection and quotation in Singapore.
