Advantages：
√ Small size and light weight. The length is only one third of the swing check valve;
√ Slow closing system, with excellent performance, is not affected by the intermediate quality of pipeline. The valve plate is quickly closed first and then slow closing, which can eliminate the destructive water hammer;
√ Rubber seal, good sealing performance, abrasion resistance and long service life; √ Smaller flow resistance than the old check valve, with obvious energy saving effect; √ The medium of the hydraulic system uses pipeline for transmission medium, without the need for secondary energy;
