In the power system, the ball valve substitutes used to replace the original drain water shut-off valve are divided into two major genres, one is MOGAS type, the valve seat is embedded and the valve body is matched and can be replaced. Seat, the other is VTI type, the valve seat is the valve body material spraying tungsten carbide or cemented carbide powder.
Two Product Features
1. One-way sealing, the main seal is made of hard alloy;
2. The valve body adopts integral forgings to completely prevent the occurrence of external leakage;
3. Following the advantages of ordinary ball valves, the sealing surface is protected from high-speed media in the open and closed positions;
4. The filler uses a moving load to ensure zero leakage of the stem packing even in the most severe thermal shocks;
