Features

The pressure self-sealing gate valve is designed for high temperature and high pressure according to API600 and ASME B16.34. Compared with the gate valve of the bolted valve cover, the pressure self-sealing has the advantage that the valve cover seal will be in the case of high pressure. Driven by its own pressure, it achieves better sealing, because this design is more suitable for high temperature and high pressure working conditions. Pressure self-sealing gate valve not only has its own stable sealing performance, but also uses iron-based and cobalt-based on the sealing surface or Butt welding of tungsten carbide can be used in more severe working conditions.
