  • Features
  • Specification

  • The SV API 6A expanding gate valve has metal seal between disc & seat and bonnet & body;
  • Secondary seal of seat can prevent impurity from going into sealing surface.
  • Plastic/chevron packing stays clean and free from contaminants to reduce maintenance costs;
  • Tight mechanical seal is assured with parallel expanding gate design;
  • Parallel expanding gate design provides upstream and downstream sealing simultaneously which is not affected by pressure fluctuation and vibration;
  • A double row roller thrust bearing on the stem makes operation easy, even under full pressure;
  • When open and close the SV API 6A expanding gate valve, there is space between gate and seat, this reduce torque.
