Fluorine-butterfly gate valve is one of the most with the opening and closing of the valve, use two sides sealed wedge shaped disc to connected or truncate the medium in pipeline, wedge gate valves are not allowed to trace open used as throttle device in the pipeline, to avoid erosion due to the high speed flow medium and speed up the sealing surface damage. Fluorine-butterfly gate sample figure

fluorine-butterfly gate structure characteristics, the body is flat and round 1 two shapes: GB valve adopts the round body, ANSI class valves DN≤ 300 lb using flat body, DN≥ 400 lb use round body, the inner cavity of valve body, bonnet and external surface of the disc, the valve stem and direct contact with the medium components, all line FEP ( F46） Fluorine plastic; 2, sealing of FPF ( F46） /聚全氟乙丙烯( F46） Or other material combination, small friction coefficient, low open-close torque; 3, packing PTFE ( F4) Standard packing, sealed performance is good, maintenance easy to change; 4, with elastic damper, can compensate gate wedge Angle deviation between seal face and seat sealing surface, good inosculation, sealing effect is ideal; 5, medium are available from any direction on both sides through the gate, suitable for medium direction may change the pipeline operator.
