Watts LFM115 GRV B 10-75 PI 2 - Part of the LFM115 Series ZA100F-8NH It has a balanced pistonThis 2 inch ACV is armed with ArmorTek, a patented 3 part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion. This pressure reducing control valve is designed to automatically reduce a fluctuating higher inlet pressure to a constant lower downstream pressure regardless of varying flow rates. The quick closing action of the valve limits the possibility of damaging high inlet pressure from
