Fluorine Lined Valve Installation

1. When installing Lined Valve, you should pay attention to check whether the valve markings (such as valve type, nominal diameter, pressure level, material, etc.) are consistent with the use requirements, and whether the flow direction mark on the shell is consistent with the flow direction of the pipeline.
2. When installing, try to install it horizontally with the valve stem facing upward. Prevent the valve from tilting and install the valve in a natural state. Prevent the valve from generating large installation stress due to pipelines, supports, etc. The hand wheel should not be used to lift the valve during installation and lifting.
3. When installing, if the pipe flange sealing surface connected to the fluoroplastic lining sealing surface at both ends of the valve is metal, a fluoroplastic sealing gasket must be added. The flange sealing surface connected to it should be in the structure of Figure A, and the structure of Figure B should not be used, otherwise it will cause premature damage and leakage of the valve sealing surface.
4. If the pipeline has sufficient strength to withstand the weight and operating torque of the valve, no support can be set for this valve. Otherwise, a special support point should be set for the fluoroplastic lining valve.
5. After installation, when the system or pipeline is pressure tested, the valve must be in the fully open position.
