Benefits

  • Additional features ensure safe sealing to atmosphere:
    • Pressure seal design: The higher the pressure in the gate valve body, the tighter the bonnet joint. Metal-capped pure graphite gasket. Very low risk of leakage, particularly at high pressures and temperatures. Compact design.
    • Graphite gland packing with packing end rings, protected against oxidation by metal caps.
