Introduction for fluoroplastic lined full port ball valve

  • Author:Cowinns
  • Source:Cowinns
  • Release on :2020-06-12
ZSHRF-16C,ZDRF-16C pneumatic/electrical Fluoroplasticlined ball valve is a rotary cut-off type floating ballvalve. It consists of a cylinder piston actuator (or electric actuator)and a fluorine-lined plastic ball valve. Because the valve cavity and ball aremade of high-pressure injection molding, lined with corrosion-resistant andaging-resistant fluoroplastic FEP (F46 for short) or PFA, it has reliablecorrosion resistance and sealing. It can be widely used in chemical industry,petroleum, medicine, electric power and other industrial sectors, to achievethe adjustment or cut off of strong corrosive media such as acid and alkali inthe production process.

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.
