Product Details

ASTM, NACE, ASME, and API standards High Temperature stainless steel float ball valve

Outline:
This corporate design whole High Temperature is uses the new packing material is seat,Makes seal after similar product teflon Ball valve,The service life enhanced 3-5 time. Has the performance stably, the seal reliable, the frictional force small, the switch facile, thermostable, wear-resisting, oil resistant, anti-corrosive, the service life long and so on the merits, “ShenGao” the sign high temperature ball valve and the cut-off valve, the plunger valve, the wash water valve, the structural length match case, expanded the ball valve use scope, widely uses in professions and so on petroleum, chemical industry, rubber, papermaking, drugs manufacture, may substitute the cut-off valve, the plunger valve, the fast wash water valve. Suitable medium: Acids and so on water, steam, heat conduction oil, application temperature: ≤350℃

Unique feature and mechanism:

In this valve spheroid, the seal packing collar have used the special processing craft and the newest packing material, causes the spheroid surface roughness and roundness meets the standard requirements, thus enhanced the sealing property and the service life, the thermostable ability.
Moves the handle impetus valve lever along the time board to actuate spheroid revolving, enable the medium to pass smoothly.
