Main Products: cng valve solenoid valve butterfly valve gate valve globe valve |
Features:
1, this valve uses three biased seal structure, the valve seat and the butterfly board does not have the attrition nearly, has the view tighter seal function.
2, with the stainless steel manufacture of seal packing ring, it has the metal hard seal and the spring-loaded seal dual merits, regardless in the low temperature and in the high temperature situation, has the fine sealing property, has anti-corrosive, service life long and so on .
3, the small dish board packing surface uses the built-up welding cobalt base hard alloy with wearability, and the long service life.
4, the big specification butterfly board uses hang a structure, the intensity is high, the overflow area is big, the resistance to flow is small.
5, this valve have the bidirectional seal function, so installs have no limit of flow directon or the influence of space position.
6, the drive may the multi-locations (revolving 90¡ã or 180¡ã) installs, is advantageous for use
