And it is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e. gasket, o-ring, precision machined, and a flat valve. Face on the upstream and downstream sides of the valve, valves have threaded inserts at both sides of the valve body this allows them to be installed into a system using two sets of bolts and no nuts. This valve installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side. Huachao Flange Concentric Butterfly Valves are with main features as bellow:Size range: 2" to 48", 50mm-1200mmPressure rating: ANSI 150#, PN10, PN16Material: cast iron and ductile iron, carbon steel, stainless steelStandard: ISO 5152, BS5155, API 609, MSS-SP-68, ASME B16.10, ASME B16.5, DIN 3202End connection: FF, RFOptional seating: resilient, NBR, EPDM, VITONActuators: manual, pneumatic, electric, hydraulic
