Pneumatic Triple Offset Metal Seat Butterfly Valve QR:Pneumatic Triple Offset  Metal Seat Butterfly Valve

Main Feature

  1. Hard-seal butterfly valve is a kind of component used to realize the on-o仔and flow control of pipeline system.
  2. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower.In the known butterfly valve technology, the sealing structure is mostly a sealed structure, and the sealing material is rubber, PTFE, and the like. Due to structurallimitations, it is not suitable for high temperature, high pressure, corrosion and wear resistance industries.
  3. The existing one of the more advanced butterfly valves is a three-eccentric metal hard-seal butterfly valve.
  4. The valve body and the valve seat are connected components, and the valve seat sealing surface layer is surfacing with temperature-resistant and corrosion-resistant alloy materials.
  5. The multi-Iayer soft stack seal is fixed on the valve plate.
  6. Compared with the traditional butterfly valve, this type of butterfly valve has high temperature resistance, easy operation, no friction when opening and closing, and the seal is increased when the torque of the transmission mechanism is increased during closing.
  7. The sealing perforrnance and the advantages of prolonged service life.
