Main feature of FX-HH49X-10/25 micro-resistance slow-closing butterfly check valve
1. Small size, light weight, and the structure length is only about one-third of the swing check valve.
2. The slow closing system has excellent performance and is not affected by the medium in the pipeline. The valve disc closes quickly first and then slowly closes to prevent destructive water hammer.
3. Rubber soft seal, good sealing performance, abrasion resistance and long service life.
4. Rubber buffer, smooth opening and closing, no vibration, no noise.
5. Compared with the old-fashioned check valve, the flow resistance is smaller, and it has obvious energy saving effect.
