FAQs

What is the primary function of this 10 inch LF870WZ-LG DC backflow preventer?

This backflow preventer is designed to protect potable water from non-health hazard pollutants by preventing backflow due to backsiphonage or backpressure. It is used in commercial and industrial applications where cross-connection control is required for non-toxic substances.

What does "Z-pattern lay length" mean for this device?

The Z-pattern lay length indicates that this assembly is specifically designed to be a direct drop-in replacement for competitor Z-pattern backflow prevention valves. This feature simplifies installation and upgrades by matching existing pipeline configurations without extensive modifications.

Is this backflow preventer supplied with shutoff valves?

No, this "LG" model (Less Shutoff Valves) is supplied without integral shutoff valves. If shutoff valves are required for your specific installation or local codes, they would need to be procured and installed separately.

What is the maximum operating pressure and temperature range for this unit?

The maximum working pressure for this 10 inch backflow preventer is 175 PSI (12.1 bar). It is designed to operate continuously within a temperature range of 33°F to 140°F (0.5°C to 60°C), ensuring consistent performance in varying conditions.

What material is the main valve body made from, and how is it protected?

The main valve body is constructed from durable Ductile Iron Grade 65-45-12. It is protected with an ArmorTek powder coating, which is epoxy coated on both internal and external surfaces for superior corrosion resistance and extended lifespan in harsh environments.
