The characteristics of industrial pneumatic valve can endure high temperature, it is suitable for pressure range is higher also, pneumatic valve nominal diameter, pneumatic valve body is made of carbon steel, pneumatic valve plate seal using metal ring instead of rubber ring.
Large high temperature pneumatic valve USES the steel plate welding manufacturing, mainly used for the duct smoke and gas of high temperature medium.
in the pneumatic valve pneumatic valve, cylindrical channels in the disc plate around the axis of rotation, rotation Angle for 0 ° - Between 90 °, rotate to 90 °, the pneumatic valve is fully open. Manual pneumatic valve has simple structure, small volume, light weight, only by a few parts. And only need to rotate 90 ° can timely opening and closing, the operation is simple, pneumatic valve has good flow control characteristics at the same time. Pneumatic valve in the fully open position, the plate thickness is medium flows through the pneumatic valve body resistance, so by the pneumatic valve pressure drop is small, so it has good flow control characteristics. Pneumatic valve has elastic seal and metal hard seal pneumatic valve two kinds of seal type. Elastic sealing pneumatic valve, sealing ring to be set on the pneumatic valve body or attached to the plate peripheral.
pneumatic valve is closed a pneumatic disc or plate for disc, revolve around pneumatic valve shaft to a pneumatic valve open and close, mainly in the line cut off and throttling. Pneumatic valve opening and closing is a disc plate, in the pneumatic valve body around its own axis of rotation, so as to achieve the aim of opening and closing or adjust. Pneumatic valve fully open to the barrier is usually less than 90 °. Pneumatic valve advantages as follows:
1, convenient opening and closing, energy saving, fluid resistance small, can often operate.
2, simple structure, small volume, light weight.
3, temperature resistance is stronger, Generally can heat resistance 650 ℃)
4, high regulation performance
the shortcoming of pneumatic valve is as follows:
1, is not easy to make small diameter
2, it is difficult to achieve full seal
