The lining fluorine valve is matched with the actuator, and has the dual function of switch and flow regulation, which can conveniently open and close the gas path without affecting the flow and ensure the repeatability of the flow. The opening is slow, reducing the impact of instantaneous pipe pressure on the meter.
Fluorine-lined valve use precautions:
1. Read the product instruction manual carefully before use.
2. Use according to the pressure, temperature and medium used on the nameplate or the manual.
3, for some media is unstable and easy to decompose (such as the decomposition of some media will cause volume expansion caused by abnormal pressure rise) can cause valve damage or leakage, measures should be taken to eliminate or limit the factors that cause the decomposition of unstable media . When selecting the valve, the fluorine-lined valve with automatic pressure relief device should be selected considering the change of working conditions caused by unstable and easy decomposition of the medium.
4. For the fluorine-lined valves on the pipes with toxic, flammable, explosive and strong corrosive media, it is strictly forbidden to replace the packing under pressure. Although the fluorine-lined valve is designed to have an upper sealing function, it is not recommended to replace the packing under pressure.
5. During the use of the fluorine-lined valve, the fluoroplastic sealing surface is soft due to the soft texture. The sealing surface is damaged due to the crystallization of the medium and the solid particles, resulting in leakage of the seal. After the discovery, the seal is repaired or replaced in time. Â
