The A.Y. McDonald 72600 series 72600T pressure reducing valve cuts incoming water pressure to a safe level to protect the plumbing system and its components. It has FNPT union inlet x FNPT outlet connections, a brass cap and a No-Lead cast bronze body, and ships factory set at 50 PSI outlet pressure, adjustable from 25 to 75 PSI. The 72600 is fully serviceable without removing the valve from the line; the 72600RK repair kit rebuilds it.
Included: one pressure reducing valve with its union end pieces, factory set at 50 PSI.
Adjusting: turn the stainless-steel adjustment bolt to set outlet pressure between 25 and 75 PSI, then lock it with the lock nut.
Covered for 1 year from the date of shipment from A.Y. McDonald’s factory under A.Y. McDonald’s published limited warranty, which applies to the products A.Y. McDonald manufactures.
