增壓閥（氣體增壓閥）：可將一般低壓氣體增壓為數(shù)倍至數(shù)十倍的高壓氣體，維持壓降的下限使出力穩(wěn)定，可增大出力改善設(shè)備壓力不足，提高生產(chǎn)線整體之壓力，在維持整體出力下，可更換缸徑較小的氣缸，以降低成本。
Booster valve (gas pressurization valve): the general low-pressure gas booster can be several times to several ten times as high pressure gas to maintain the lower limit of pressure drop to contribute to stable and increasing pressure to contribute to improve their facilities inadequate, the pressure to improve the overall production , while maintaining the overall contribute, it can be to replace a smaller cylinder bore in order to reduce costs.
