ISO 5211 ACTUATOR ASSEMBLY
The ZPL510WF FEP-Lined Pneumatic Bellows Sealed Regulating Valve are coated with a layer of fluoroplastic on the inner-surface of the valve body and valve spool that comes into contact with the fluid, completely cutting off the corrosive media from the metal and effectively blocking the corrosive media from corroding all metal materials. It has good sealing performance,responsive action, precise flow characteristic, and is widely used in strong corrosive media such as acids, alkalis, salts and gaseous and liquid media that are easy to volatilize and penetrate.
The Classification Of ZPL500 Series:
1.ZPL510F Packing Seal Fluorine-Lined Regulating Valve;
2.ZPL510WF Bellows +Packing Seal Fluorne-Lined Regulating Valve;
3.ZPL520F Fluorine-Lined Balanced type Regulating Valve.
ZPL510WF PTFE-lined control valve (Bellows seal and 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(Hartz Alloy)sealing and V-shaped PTFE packing two kinds of combined sealing
structure to ensure no leakage.
3. Low inner leakage : achieved through the utilization of soft-seal for the valve spool and valve seat.
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 valve or shut-off valves.
