Cast Steel Astm A216-Wcb Pneumatic Fluorine Lined Regulating And Control Valve
Product introduction:
The L202301 series straight stroke fluorine lined regulating and control valve adopts a fluorine lined structure for both the valve body and internal components, effectively blocking the corrosion of corrosive media on all metal materials in the valve body. The inner cavity of the metal valve body is processed in a toothed manner, allowing the lining material to fully bond with the metal, thereby increasing the service life and performance of the lining material. The valve stem seal adopts a combination of PTFE bellow pipe seal and V-shaped PTFE packing, completely eliminating the leakage of medium from the valve stem outward. The unbalanced fully lined fluorine control valve is particularly suitable for the use of highly corrosive media under low pressure and normal temperature conditions.

Product features:
1. Fluorine lined regulating valve is a type of regulating valve with a secondary permeation structure, which is composed of a metal or plastic skeleton and fluorine lined materials inside. Fluorine lining material is a fluoroplastic material with corrosion resistance, which has excellent acid resistance, alkali resistance, and high temperature resistance. Generally speaking, fluorine lined regulating valves can withstand temperatures up to 200 degrees, and even higher temperature mediums.
2. Fluorine lined regulating valves have high temperature resistance, corrosion resistance, high precision, stability, and long service life. Therefore, it has a wide range of applications in fluid control fields such as chemical, petroleum, and metallurgy.
