Butterfly pneumatic valve with automatic cleaning function

service life: butterfly pneumatic valve in use, more than once and still provide 'airtight' shut off. Pressure drop: if the pressure drop is too big, can increase energy consumption. However, it should know is that pneumatic valve and is not the sole cause of the piping system pressure drop, leading to the formation of pressure drop and the following factors. Cross section of flow of the pipeline. Wall of pipeline caused by friction. Through parts to change. Butterfly pneumatic valve flow characteristics is equivalent to three times or more by the pneumatic valve, pneumatic valve is equivalent to the same size of the gate of %. Generality: butterfly pneumatic valve used for on/off service and throttling/balancing pipeline system to control and adjust. Compared with the pneumatic valve or by the pneumatic brake valve, pneumatic valve adjustment has better 'universality'. Due to the adjustment of pneumatic valve can be used in a variety of surface treatment technology and the choice of elastic material pipe so butterfly pneumatic valve with a strong chemical resistance. Weight: light control pneumatic valve installation cost is larger than that of heavy cast iron pneumatic valve save: for example, a nominal size inches blockbuster the pneumatic butterfly valve, pneumatic valve weight one inch cast anchorman is as high as pounds. For the whole pipeline system, using the butterfly saved by pneumatic valve installation cost is very considerable. The heavier in addition, the pipeline system, the stronger the pipe hangers, thus lead to the whole pipeline system is more expensive. To, considering the weight of the pneumatic valve, can save the cost of the whole pipeline system. Size: butterfly pneumatic valve space is about the same size of the brake/pneumatic valve. And for every cubic feet of building space, means that the cost of waste. Inches nominal diameter, for example, the pneumatic butterfly valve is about inches tall, while inch brake pneumatic valve nominal diameter up to inches. Tight closure: brake pneumatic valve and globe valve ( Metal to metal) The pneumatic valve seat does not have airtight closed performance. Easy operation: butterfly pneumatic valve from open to closed only need to rotate/( C) 。 Pneumatic valve and globe pneumatic brake valve need to rotate much go to converting pneumatic valve from open to closed. Easy open or closed means don't need to hire the operator of the salary is too high to butterfly pneumatic valve operation. Cost: the cost of a butterfly pneumatic valve usually only cast anchorman % of pneumatic valve, which not only low initial cost, but low installation costs also. Maintenance: due to the adjustment of their pneumatic valve has the very high performance and good elastic pneumatic valve seat, so butterfly pneumatic valve with automatic cleaning function, reduce the possibility of a pipeline is garbage sundry jam.
