Construction Features
1.the valve uses the fixed spheroid,Fluctuation valve seat structural style is new and unique, the seal is reliable.
2. the special material quality seal,stand fire, tha wear ability, the lifeare long.
3. on the valve shaft is equipped with guards against escapes the organization,
if in the medium pressure of situationalso can adjust thepadding.
4. the valve seat has fine structure, specially makes together in the valveseat,mg surface inside precision work wear-resisting seals the circle.
When seals the circle serious attrition, seals vice-forms the temporary metal with the spheroid between to the metal seal, the valve padding filling piece uses the thermos table graphite material, guaranteed the valve occurs when the high temperature outside does not have leaks.
5. the transmission device has kinds of.

the characteristic of ash ball valve and drawing down, besides before states below, but also has the, characteristic:
1.the weight is lighter than other valve
2.when the medium enters by the import direction, forms one kind of extrusion the impulse, the medium circulates by the export ation, thus realizes theeffect which one kind spurts blows.Note: because ours company improve the drawing down cinder-ball-valve is more wear-resisting than others and has the high strength also has fineperformance.Main External and Connection Dimension| DN | L | D | D1 | D2 | b | f | Z- 4)d | H1 | H2 | Lo | Weight |
