The Improvement of Full Open Style Silent Check Valve on Flow Rate
| The full open style silent check
valve adapts the lift open style plug and the plug has hidden bypass
design, which will cause the smallest resistance on valve inside surface. When fluid flow through the valve, and hence, will reduce the loss of pump running effect and improve the power efficiency. Since that, the defects of traditional silent check valve, e.g. many turning points, large resistance, not smooth flow way and fluid impact the valve directly and shorten the valve life, have been improved. |

The Improvement of Full Open Style Silent Check Valve on Pressure-Resistance
 The hang type plug design can match sealing of the up-side-down " V" type sealing. It can adjust the closedown position of the plug and seat, no matter the pressure is high or low, and won't be affected by cantilever. |

The full open silent check valve adopts
the round-arch type design. After the mechanics calculation and fluid pressure model test, the performance is excellent. |
 The special design of the up-side-down "V" sealing of the full open silent check valve can offer the best closedown performance when the valve is close (as shown on the figure). When the fluid pressure is low , the sharp end of the up-side-down "V" sealing will double-close down with seat. If the fluid pressure increase,when the plug presses downward, the sharp end of the up- side-down "V" type will develop outward to increase the attached area of the rubber. |
 Under the high fluid pressure situation, the full open silent check valve will close its plug and seat via metal-to-metal type (shown as the figure) to prevent the sealing over-pressed to become fatigue. At the same time, the up-side- down "V" type sealing develops outward to perform an excellent closedown (shown as the figure). |
