Diaphragm Valve for Ultra High Purity AP

    ・For UHP gas delivery in semiconductor and other clean industries
    ・Used as a gas shutoff valve
    ・No spring is used for the wetted parts and the drive part is also separated from the diaphragm. Dead space in the flow path is small in order to suppress particle generation.

■Diaphragm Valve for Ultra High Purity Series AP
  • For UHP gas delivery in semiconductor and other clean industries.
  • Used as gas shutoff valve.
  • No spring is used for the wetted parts and drive part is also separated
    from the diaphragm. Dead space in the flow path is small to suppress
    the particle generation.
■Check Valve/Vacuum Generator/Flow Switch Series AP

[Check valve]

  • Fluid back-flow is prevented by back pressure.
  • Unique design with only one moving part in the gas stream, an O-ring.
  • Springless structure suppresses particle generation by vibration or
    chattering or pressure fluctuation on downstream side.

[Vacuum generator]

  • Vacuum generation equipment.
  • Applicable to emission of unnecessary gas remaining inside the
    piping during gas cylinder replacement.

[Flow switch]

  • Detects excess flow above a given flow rate, caused by pipe breakage, etc.
