1. The body adopts "waist drum" design. It can improve the medium flow direction and reduce the flux- blocking modulus.
2. The guiding rack adopt streamline design, the energy cost is low.
3. Compared to tradition valve clacks, the new valve clack adopts "non-edge" streamline design. It is able to make medium circulate much better; it can not produce any extra resistance because of the medium rebound.
4. The sealing washer and body make a whole, which avoid medium scour the sealing washer for a long time, make the valve sturdy and durable.
5. Because of metalloid lubricating bush between guiding axis and the guiding rack, the valve clack goes up and down nimbly, can not come into being locked.
6. The valve spindle guiding centre and detach, it may not out of the body seal face when the valve opening or closing. So other valve can be assembled at both sides of the valve, became one combination valve. The combination valve can be used as one bottom valve.
7. The body, the guiding rack and the valve clack are streamline designs, so that the medium flow silently and the designs according with the rules of hydrodynamics, does not produce any water hammer.
