■Regulators for Ultra High Purity (UHP) Series AP/SL/AZ

■Regulator/Back Pressure Regulator for General Applications Series AK/BP

■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]
