Pneumatic plastic diaphragm valve
Pneumatic plastic diaphragm valve
公称通径：DN15~200
工作温度：-14℃～+140℃
控制压力：4-6bar(Control mode 1)，3-4bar(Control modes 2 and 3)
隔膜材料：RPP or PVDF injection parts
Advantages
1. It is suitable for the
transportation of corrosive media and the regulation of interception and
flow rate. According to the different materials, it can be used at
temperatures ranging from - 14℃ to +140℃.
2. The over-current parts are assembled by RPP or PVDF injection moulding parts, which have excellent corrosion resistance.
3.
The sealing diaphragm is made of F46 or PFA, and its folding resistance
is more than 12000 times. Its corrosion resistance is similar to that
of F4.
4. The screw lifting structure is adopted with large opening and closing moment and good stability.
