Product features

Pneumatic PP plastic butterfly valve has the characteristics of light weight, strong corrosion resistance, hygienic and non-toxic material, wear resistance, easy disassembly and simple maintenance. It is applied in many fields, such as pipeline system of general pure water and raw drinking water, drainage and sewage pipeline system, brine and seawater pipeline system, acid-base and chemical solution system, etc.
 Structure of pneumatic PP butterfly valve
Features of pneumatic PP butterfly valve:
 
1. The hygienic index of pneumatic PP butterfly valve meets the requirements of national health standard, and the heavy ion content in medium reaches the ultra pure water standard.
2. It has excellent strength and toughness, smooth pipe wall, low friction resistance and adhesion when conveying fluid.
3. The pneumatic PP butterfly valve has excellent chemical corrosion resistance and flame retardancy is self extinguishing.
4. Light weight, equivalent to 1 / 5 of steel pipe and 1 / 6 of copper pipe. Low thermal conductivity, about 1 / 200 of steel.
5. Pneumatic PP butterfly valve has excellent anti-aging and anti ultraviolet performance, so that its normal service life is greatly improved compared with other pipeline systems.
