Comparison of PFA
China PFA lined ball valve manufacturer has chosen to use steel castings lined with high molecular weight PFA’s for its lined fittings. The reasons for this are technical and not cost driven. The use of PFA in castings provides the best combination of lining performance, housing strength and consistency.

PFA Lined valves Inspection and Testing
Polymer batch numbers are linked to the manufacturers material certificate Discrete batches of polymer are not mixed. The bach number of the polymer used is recorded on the moulding log sheet against a specific mould reference. FPA lined valve testing, The PFA we use meets the requirements of ASTM D3307 Type 2. They are also specified as having a restricted melt flow index not exceeding 3 grammes in 10 miniutes. We extensively use our own in house melt flow indexing test equiment to ensure the PFA Lined ball valve complies to our strict quality controls.

Wafer-style butterfly valves
The wafer style PTFE lined butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this by using a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.

Features Events and Processes
FEP lined butterfly valve FEP is terms used in the field of radioactive waste management to define relevant scenarios for safety assessment studies. For a radioactive waste repository, features would include the characteristics of the site, such as the type of soil or geological formation the repository is to be built on or under. Events would include things that may or will occur in the future, like, e.g., glaciations, droughts, earthquakes, or formation of faults. Processes are things that are ongoing, such as the erosion or subsidence of the landform where the site is located on, or near.
