Check Valve / Vacuum Generator / Flow Switch

[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. Series Type Body material Connection type Connection size AP Check valve 316L SS secondary remelt Face seal Tube weld 1/4'', 3/8'' AP Vacuum generator 316L SS Face seal Tube weld 1/4'', 3/8'' AP Flow switch 316L SS secondary remelt 316L SS Face seal Tube weld 1/2'', 3/4''
