USES:
Card card sets of valve and pipeline in a set of links, prevent leakage, metal.Card sets of valve is widely used in petroleum, chemical, natural gas, power station, metallurgy, national defense scientific research and other fields.
Features:
1) small size, light weight, simple structure, disassembling easy;
2) connect the relay is strong, wide use, resistant to high voltage (1000 kg/cm2), high temperature (650 ℃) and impact vibration;
3) can be a variety of materials, suitable for corrosion protection;
4) the processing accuracy is not high;
5) easy to high altitude installation.
