A.Y. McDonald’s new slimmer Inline Dual Check Valve helps protect the public water supply by preventing the reverse flow of water from the building back into the water main. The valve is able to hold 1 psi in the direction of the flow and can endure a temperature rating of 34°F to 180°F. The A.Y. McDonald Inline Dual Check offers extra versatility as the valve can be installed in either a horizontal or vertical position. In addition, the ASSE 1024 certified part provides easy access to check for inspection, maintenance or replacement. www.aymcdonald.com
