Concentric Butterly Valve

Categories

The disc rotates on the pipe centerline, sealing against a resilient seat – that’s the whole mechanism. This valve is classified as a low‑cost shut‑off valve used for water distribution, HVAC, irrigation, and other utility duties. Water, wastewater, air, and other non‑critical utilities – this valve was made for that. Simplicity keeps cost low. Fewer parts mean less maintenance. Low torque allows manual operation without gearboxes. Forget about complex installation – it fits between flanges and just works.
