Product Description Model NO.: N/A Certification: ISO, RoHS Feature: Wear Resistant Surface Roughness: Ra0.05 Trademark: Actech Specification: DN15- DN200 HS Code: 8547100000 Application: Construction, Petroleum Material: Zirconia and Alumina Corrosion Rate: 0.001-0.01 Lead Time: 15-30days Transport Package: Carton or Wooden Case Packaging Origin: China   Besides some advantages of metal valve, it can also resist corrosion, high temperature,
wear and erosion. It can be used in different kinds of acids bases and salts gas, liquid,
stream and slurry transportation system in the industry of petrifaction, metallurgy, paper
making, power station and oil refining.
   This is the best substitute product for titanium and Monel valve when it is strongly
corroded.Meanwhile, it is effective and long time operating (2 to 4 times than titanium valve)
with low cost. And it can be driven by hand, air, spring return pneumatic, electron and etc.
As for special valve, we can design it as customers' needs.
