This kind of butterfly valve is concentric (center line) with resilient seat It can be installed between two flanges using bolts or nuts and studs. Compared with other butterfly valve, it has higher performance to prevent the tube from leakage. It is widely utilized in foodstuff, pharmacy, chemical industry, environmental protection, water treatment, high building, water supply and draining industry and more.
U type butterfly valve is different from wafer or lug type butterfly valve, because it is flange connection. The size we can offer is from DN150(6") to DN1200(48") Working temperature: _15°C to 150°C Working pressure: PN10, PN16
