Ball Screw Gate Valves
provided by Leland is a type of large bore gate high pressure valve which were improved from Cameron FLS-R gate valve, it’s the main component of frac tree, the frac valve is often used on the top of the wellhead on high pressure oil well, can do the frac job for isolating the fluid from the well.
The body and flanges are integral (non-welding). Shot Blasting for every parts of valve. Phosphating to improve corrosion resistance.
