Imported pneumatic gate valve
Overview
  YLOK imported pneumatic gate valve (pneumatic stainless steel gate valve, pneumatic flange gate valve, pneumatic fluorine-lined gate valve), which is driven by compressed air. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure Press the sealing surface of the gate against the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate must be forced against the seat by external force to ensure the sealing performance of the sealing surface
