Resideo FM911 Backflow Preventer Pressure Reducing Valve 12PSI 1/2" NPT/Sweat

The Resideo FM911 Backflow Preventer Pressure Reducing Valve is a critical device for protecting hot water systems from harm. This valve is available in a 1/2" NPT/Sweat connection and is ideal for use in HVAC and plumbing systems. It ensures that the pressure of the water does not go beyond 12 PSI avoiding pressure that is dangerous to the product. The backflow protection mechanism of the valve is to prevent reverse flow and thus guarantee your water supply is not contaminated. Having a nominal pipe size of 1" and a DN size of DN15 ensures pressure and flow regulation.
