Pressure Seal Bonnet Gate Valve
Pressure seal bonnet gate valve is sealed by media pressure, and the pressure is more, the sealing is more reliable. On valve bonnet, there is a smooth cone which has self tight seal ring. This type valve is applied to chemical fuel electric power station. It is more simple than bolt bonnet type gate valve.
