CHARACTERISTICS:
1. The design of tri-eccentric butterfly valve, called as apical process control valve is ideal for hard sealing butterfly valve of moderate bubble seal applied in occasions under high temperature, high pressure and fire prevention.
2. The application of welded structure ensures permanent zero leakage between valve and pipe plane;
3. Flange free facilitates the pipe insulation envelope with beautiful outline.
