Amico's Zone Valve Boxes (like all Amico products) are built with quality in mind. Each valve includes a large color-coded gas identification label strategically placed for the highest degree of visibility. Zone valve boxes can be configured to hold 1 to 6 valves with or without monitoring gauges. Isolation valves are available with an optional purge port.
