Ball Check Valve
ADVANTAGES:
1) New CUP shape ball can stop water by just 0.5kg pressure
2) Materials meet drinking water standard
3) The material has been modified by nanometer,improving the pressure resistance and impact resistance
4) Raw materials add anti ultraviolet absorbent and antioxidant, improving the durability, ageing resistance  
5) Can be assembled vertically or horizontally

DESIGNS

① Union-end plane after turning to ensure a more reliable flatness
② Increase the nut-solid, thread taper and laps, improved pressure-resistant
③ Thickening Oring, more toughness, sealing better
④ Seat is designed to fix the sealing performance
⑤ From the platform to the half-ball sealing, more reliable performance, sealing pressure levels increased (0.5kg-10kg), and it can easy to install by horizontal or vertical
⑥ In the ribs from three to six, making better diversion
