ZPL510F fluorine-lined regulating valve (packing seal) is constructed with a high-temperature molding process fluorineplastic lining material, ensuring that the inner surface and internal components of the valve are covered with fluoroplastic. With roughed processing on metal’s surface , the lining material is securely bonded, significantly enhancing both its working life and performance. This valve effectively isolates corrosive mediums from contacting any metal materials within its structure, providing exceptional resistance against corrosion. With excellent sealing capabilities, responsive action, and precise flow characteristics, it finds extensive applications in environments involving strong corrosive media such as acids, alkalis, salts as well as volatile and penetrative gas or liquid substances.

ZPL510WF PTFE-lined control valve (Bellows seal+packing seal) has the performance of ZPL510F valve stem seal structure, and adds PTFE Bellows seal and V-shaped PTFE packing as two combination seals. This eliminates any leakage of the media from the valve stem. It can achieve multiple sealing protection to prevent media leakage and provide better sealing guarantee for demanding media (chlorine,liquid chlorine, etc., which are highly toxic and strongly corrosive).

The Advantage Of ZPL510WF:
1. Corrosion resistance: corrosion resistance of almost all media (including concentrated nitric acid and aqua regia).
2. Good sealing performance: PTFE Bellows or HC sealing and V-shaped PTFE packing two kinds of combined sealing structure to ensure no leakage.
3. The fluid channel is parallel streamlined, with low pressure drop loss.
4.Removable bottom valve cover for easy removal of impurities and residual crystals.
5.Top-entry construction and quick-change trim for easy maintenance.
6.Wide material selection available for different applications.

Users can select the suitable valve goods based on specific operating conditions (including pressure differential, temperature, and medium state)
◇ The ZPL510F fluorine-lined regulating valve (packing seal) is specifically designed for general corrosive media applications.
◇ The ZPL510WF fluorine-lined regulating valve (Bellows seal + packing seal) is specially engineered to handle highly toxic and extremely corrosive media with strong penetration capabilities, such as chlorine, liquid chlorine, bromine, etc.
◇ The products are suitable for low-pressure differentials (within 0.5MPa) and corrosive media, with a temperature range of -35℃ to 160℃, applicable for pipe diameters up to DN50. For high-pressure differential corrosive media like liquid chlorine, we recommend selecting our metal regulating and shut-off valves.
