性能特點： Performance characteristcs：
1. The valve body has quality forging and after melts processing (rmly. This can guarantee that does not have the inside and outs
2. The valve seat built-up welding cobalt base hard alloy, this can enhance the high temperature degree of hardness and anti-med
ium eroding ability enormously.
3. The valve petal uses the cobalt chrome tungsten steel ball. It has the very high high temperature degree of hardness. This can
cause its an-medium eroding ability to surpass the ordinary needle valve
4. The va e stem is forged, its flexibility and intensity different general. The trundle processed thread located at padding above.
this can avoid contact with the medium, The polished rod spot is processed by correct gridding. This can guarantee the close con
tact with the padding. The valve has no outside leaks. This design can also reduce the opening moment of force and the valve op
ens shuts time nimble freely
5. The unique design mouth metal gasket is manufactured by special craft quenching treatment. This can guarantee the good se
al in the high temperature and high pressure.
6. The compact fine flexible graphite padding, has guaranteed the valve has not outside leaks in the high temperature high press
