Z673X pneumatic slurry valve continuously digests and absorbs the advanced features of similar product structures and manufacturing processes at home and abroad in the process of production and application. Continuously improve the scientific and technological content of the products, starting from some technical details, and improve the comprehensive performance of the valve. The product can complete the automatic control of the opening and closing of the two positions through the use of accessories such as solenoid valves. Users can choose according to actual needs.
Z673 series pneumatic slurry valve has a complete variety. The main body is made of cast iron, cast copper, stainless steel, etc. The diameter is from DN50 to DN10000. Products are widely used in chemical, coal, sugar, sewage, paper and other fields, is an ideal sealing valve. It is especially suitable for adjustment and throttling on pipelines in the paper industry.
The valve is mainly composed of left and right valve bodies, U-shaped sealing ring, gate plate, steel nut, valve stem, bracket, handwheel and other parts. The valve is opened and closed by rotating the handwheel. When it rotates clockwise, the valve is closed. ; On the contrary, it is to open the valve.
Structural features:
1. The clip-on structure is adopted, which is small in size and light in weight.
2. The completely open channel can prevent the medium from depositing in the valve.
3. The newly developed U-shaped sealing ring can ensure the good sealing performance of the valve.
4. The outer sealing of the gate is realized by an elastic sealing strip embedded in the valve body, and can be adjusted by means of screws and pressing plates.
5. Small flow resistance.
6. Easy installation and maintenance.
