DIG Shut-Off and Air Relief Valves

DIG shut-off and air relief valves are essential accessories for controlling flow and protecting drip and low-volume systems. Shut-off valves isolate sections or individual lines for maintenance, while air vacuum relief valves admit and release air to prevent siphoning of debris into emitters and to protect the system from vacuum conditions.

Available in barb, FNPT, MNPT, and hose-thread connections across 1/4 in. to 1 in. sizes, these valves install on supply lines, laterals, and at high points of the system. Flush valves clear sediment from line ends during maintenance.
