Pressure Sealing Forged Gate Valve

Pressure Sealing Forged Gate Valve is designed for high temperature and high pressure according to API600 and ASME B16.34. Compared with bolted bonnet gate valve, the advantage of pressure self-sealing is that the bonnet is sealed under high pressure. The ring will achieve better sealing under its own pressure, so this design is more suitable for high temperature and high pressure working conditions.

The Pressure Sealing Forged Gate Valve not only has its own stable sealing performance, but also the sealing surface adopts iron-based and cobalt-based or tungsten carbide butt welding, which can be used in more severe working conditions
