PFA polytetrafluoroethylene valves, fittings
The introduction of PFA polytetrafluoroethylene valves, fittings:
Polytetrafluoroethylene (PFA) valves, connectors: chemical tolerance, can withstand chemical solvents. Can be used as a variety of chromatographs, chemical equipment and other pipeline connection control. Divided into the same diameter reducing.
1. Appearance translucent jade.
2. High and low temperature resistance: can be used temperature -200℃ ~ +250℃.
3. Corrosion resistance: strong acid, strong alkali, aqua regia and various organic solvents, and no dissolution, adsorption and precipitation phenomenon.
4. Anti-pollution: low blank value of metal elements.
5.Insulation: not affected by the environment and frequency, small dielectric loss, high breakdown voltage.
6. Atmospheric aging resistance, radiation resistance and low permeability.
7. Self-lubricity: small friction coefficient of plastic.
8. The surface is not sticky: it is a solid material with small surface energy.
9. Soft mechanical properties, with very low surface energy.
Currently in stock are 2/3 valves connected to 1/4 inch pipe
Widely used in national defense, nuclear energy, petroleum, radio, electric machinery, chemical industry and other important sectors.
Connection mode: card type connection, thread type connection, welding type
