Available for potable applications, our lead-free commercial and home water pressure regulator has the most advanced design in the industry. EB25 design benefits include:; Rock-steady outflow even with extreme variations in supply pressure; Patented single-cartridge design that has fewer parts for increased reliability; Easily adjustable cartridge that can be serviced without removing the valve body; Innovative ''micro-fingers'' that dissipate noise as water flows across the seat, eliminating water whistle or harmonic hum associated with most water pressure regulating valves.
