Características y ventajas
·Compared with the ordinary butterfly valve, DB type butterfly valve without internal mechanical (fasteners) connection, no mechanical connection failure possible, alta fiabilidad, better able to adapt to harsh conditions.
·Filling epoxy resin technology to make the valve plate and the valve seat on the entire contact surface has the same amount of interference, eliminating machining and assembly errors, the pressure is uniform, reduce operating torque, reduce the wear of the sealing surface.
·Through the external injection port on the valve sealing surface in the use of the normal wear or due to minor damage caused by pipeline magazine to adjust, without the need to remove the pipeline, to achieve online repair with pressure.
·And the valve plate adopts the truss structure design, the relative before the traditional shape of the valve plate can reduce weight, but also improves the strength, while maintaining a large free flow area, increase the flow coefficient, reduce head loss, reduce the valve erosion.
