Product details
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, papermaking, power station and oil refining.

This is the best substitute product for titanium and Monel valve when it is stronglycorroded.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.
