增压阀（气体增压阀）：可将一般低压气体增压为数倍至数十倍的高压气体，维持压降的下限使出力稳定，可增大出力改善设备压力不足，提高生产线整体之压力，在维持整体出力下，可更换缸径较小的气缸，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.
