Introduction for fluoroplastic lined full port ball valve
- Author:Cowinns
- Source:Cowinns
- Release on:2020-06-12
Product advantages:
1. Corrosion resistance: The wide internalcavity and the sphere are lined with 2.5~3mm thick F46 or PFA, which can resistacid, alkali and strong corrosion.
2. Adopt soft sealing valve seat, goodsealing performance.
3. Small size, light weight, simplestructure, convenient installation and maintenance.
4. Small flow resistance and largecirculation capacity.
5. If equipped with a valve positioner,proportional adjustment can be achieved.
6. The valve can be equipped with varioustypes of electric actuators, and it is matched with ZDRF-16C type electricfluorine lining plastic type O type ball valve.
