Hydrant Gate Valves are available in both aluminum and brass. They are designed with brass non-rising internal stems. The aluminum body, internal gate and the inlet/outlet fittings are hard anodized for maximum protection against corrosion. The units take 10 turns to open or close. Both the HGV25 (4 lbs) and the HGV25B (9 lbs.) are equipped with 2-1/2" swivel inlets and 2-1/2" NST rigid male outlets.
