Fluorine Lined Control Valve provides globe-type Control Valves for controlling corrosive and/or poisonous fluids. The body cavity, valve plug, valve seat, and valve stem are all lined with material F46 or PFA in thickness of 2.5 - 3mm to resist acid, alkali, and strong corrosion. The valve is suitable for controlling medium with strong acids, strong alkalis, volatile, and easy penetration, so it is widely applied in industrial automation devices with special media control systems, including chemical, petroleum, metallurgy, medicine, textile, etc.
Features:
1. With double sealing characteristics of PTFE bellows seal and V type PTFE packing seal, to prevent medium leakage
2. The lining material F46 and PFA can be used to get the maximum temperature resistance of 140 and 200 degrees Celsius
3. Hastelloy alloy plug, valve stem, and valve seat can be used to ensure valve service life in case the valve plug and valve seat lined with material F45/PFA is not able to meet the required hardness in occasions of flash and cavitation
