Mueller Industries gate valves allow complete shut-off or fully open fluid flow in compressed air systems and water pipelines. These units feature cast-iron wheel handles for rotating the stem, which then moves the gate up / down via the FNPT threaded ports. They come with screw-in bonnets for creating a leak-proof seal inside the valve and wedge-shaped gates to provide a non-sticky seating when exposed to high differential pressures. Choose from a wide range of these brass gate valves available in pipe sizes ranging from 3/4 to 2 inches on Raptor Supplies, a Mueller Industries distributor.
