Specifications

  • Non-maintance design,inside and outside electrostatic epoxy resin powder coating,the valve can be installed under the ground directly.
  • The valve adopts the back seal and the stem seal,those double seals can avoid any top leakage when installation.
  • The customer can easily replace the top seal "O" rings under the pressure.
  • The valve adopts flat bottom designing ensures no dead space and very little flow resistance.
  • The wedge adopts bidirectional groove design ensures the best reliable seal.
  • A set of seal pressure angle adopts gradual design.
  • The pressured surface of setm adopts high strength self-lubricated materials,the valve can be opened and closed easily.
  • The bonnet,body castings adopts equal thickness design to avoid the outside leakage by the stess function.
