Our exclusive X series revolutionizes valve maintenance. All parts are stainless steel and impervious to rust. Instead of a bolted flanged connection, a circular clamp secures the valve head to the body. With Air & Vacuum, Pressure Air Release and Combination assemblies, all feature our Head Exchange System, with head-fixed internals. To clean, loosen the head assembly. Pull out the original head, pop in a spare, and clean the original internals at your leisure.
