DK55-CF Extreme Corrosion-Resistant Electric PTFE-Lined Flanged Ball Valve for Chemical Media
The Electric PTFE-Lined Flanged Ball Valve offers low fluid resistance and fast switching for corrosive applications. Featuring a FEP lining and full bore structure, it provides extremely high chemical stability for nearly all strong corrosive media, ensuring reliable, leak-free shut-off and easy pipeline maintenance.
Size Range: DN15-DN350
Material: WCB, Stainless Steel etc.
Connection Standard: GB / ANSI / JIS /DIN
Features
Unmatched Chemical Stability and Reliable Full Bore Design
✅ Exceptional Chemical Corrosion Resistance: The FEP lining layer provides extremely high chemical stability, allowing the valve to be applied to almost any strong corrosive property media, excluding only molten alkali metals and elemental fluorine.
✅ Full Bore Structure for High Flow and Easy Maintenance: Adopting a full bore and floating ball structure, the valve cavity provides a low-resistance, straight-through flow channel, which also simplifies pipeline system maintenance and media passage.
✅ Leak-Free Sealing Across the Entire Pressure Range: The design ensures the valve can be closed without leakage throughout the entire pressure range, offering reliable tight shut-off performance for critical applications.
✅ Versatile Actuator Control Options: The electric actuator supports various control modes, including basic ON/OFF switching and precise regulation (0° to 90°). Multi-turn and explosion-proof types are also available.
✅ Durable and Highly Protected Actuator Enclosure: The actuator body is made of hard aluminum alloy, treated with hard anodic oxidation and Polyester powder coating, providing excellent corrosion resistance and a standard waterproof protection class of IP65.
