Chemical Anti-corrosion Pneumatic Fluorine Lined Butterfly Valve Wafer Connection Cast Steel Pneumatic Butterfly Valve
Full Fluorine Lined Anti-corrosion Design The valve body and butterfly plate are integrally lined with F46 fluoroplastic, completely isolating the medium from the cast steel base material, resisting almost all strong acids, strong alkalis, organic solvents and oxidants.
High-strength WCB Cast Steel Valve Body Adopt WCB carbon steel cast body, high structural strength, stable pressure resistance up to PN16, not easy to deform under high pressure, suitable for long-term continuous industrial pipeline operation.
Excellent Sealing Performance Fluorine soft seal realizes bubble-tight zero leakage shut-off, wide applicable temperature range from -20℃ to 150℃, wear-resistant, aging-resistant and excellent sealing stability.
Reliable Rack & Pinion Pneumatic Actuator Aluminum alloy pneumatic actuator with blue anti-corrosion coating, optional double acting / spring return fail-safe type, fast 90° switch, equipped with mechanical position indicator and stroke fine-tuning bolts.
Wafer Compact Installation Structure Standard wafer connection, clamped between two pipeline flanges, no need for supporting valve flanges, effectively saving installation space and project procurement cost.
ISO5211 Standard High Mounting Platform Universal top flange design, can be directly equipped with solenoid valve, limit switch and valve positioner to realize remote PLC automatic control and flow regulation.
IP65 Dustproof & Waterproof Protection Grade The actuator can work stably in humid, dusty chemical workshops, and can be customized to ATEX explosion-proof configuration for flammable and explosive working conditions.
Complete Specifications & Custom Service Full size range from DN50 to DN400, support OEM/ODM customization of actuator type, lining material and complete set of automatic accessories to provide anti-corrosion pipeline valve solution.
