Characteristics

Three eccentric sealing structure, the valve seat opens and closes without friction, no wear, no jam

Pure metal hard seal, no fear of medium scouring, longer life

Excellent gas and liquid insulation, two-way seal, zero leakage

Easy to replace and adjust the sealing performance of the sealing pair for easy maintenance

Low operating torque and reliable torque shutoff

The valve series are all designed for double half shaft, high Kv circulation value

There are national standard and European standard for welding end, which can be directly welded to the pipeline without preheating.

Suitable for harsh environments such as high temperature and high pressure and corrosive, up to 600 ° C

Wide range of applications, almost in all industrial fields
