FAQs

What is the primary purpose of the Zurn 375DA Reduced Pressure Detector Assembly?

The Zurn 375DA is designed for installation on water lines in fire protection systems to prevent contaminated water from flowing back into the potable water supply due to backsiphonage or backpressure.

What does "FLG X FLG, LESS GATE VALVES" signify for this model?

"FLG X FLG" indicates that the backflow preventer has flanged connections on both the inlet and outlet sides. "LESS GATE VALVES" means that shut-off valves are not included with the unit and must be sourced separately.

What are the key materials used in the construction of the Zurn 375DA?

The main valve body and access covers are made of epoxy-coated Ductile Iron ASTM A536. Internals, fasteners, and springs are stainless steel, with NORYL™ components and EPDM/Buna Nitrile elastomers.

What are the maximum operating pressure and temperature ratings for this backflow assembly?

This 2 1/2 inch Zurn 375DA model has a maximum working water pressure of 175 PSI and a maximum working water temperature of 140°F.

How does the metered bypass feature benefit the system?

The metered bypass allows for the detection of small leaks within the fire protection system and helps identify any unauthorized water usage, contributing to lower lifecycle costs.
