Electric Fluorine-Lined Ball Valves (FEP / PFA Lined)
DELCO electric fluorine-lined ball valves are engineered to conquer the world’s most aggressive fluid applications. By completely encapsulating the valve body and internal trim with thick virgin fluoropolymer resin, corrosive media is entirely isolated from metallic contact. This delivers total chemical resistance equivalent to exotic alloys (هاستيلوي, التيتانيوم) at a fraction of the capital cost, providing reliable remote On/Off isolation or high-precision 4-20mA proportional throttling.
FEP (F46) Fluoropolymer Lining
نطاق الحرارة: -20°C إلى 150°C (-4°F إلى 302°F)
Extremely dense molecular structure with proven anti-permeation. المعيار الصناعي, cost-effective choice for over 90% of medium-temperature strong acid, قلوي, and salt pipelines.
PFA Fluoropolymer Lining
نطاق الحرارة: -20°C إلى 200°C (-4°F to 392°F)
Superior thermal stability, melt-processible integrity, and high-temp mechanical strength. Essential for boiling acids, volatile organic chemicals, and continuous full-vacuum systems.
Why Choose DELCO Electric Fluorine-Lined Ball Valves?
Engineered for zero-leakage performance, high-vacuum endurance, and severe chemical protection.
100% High-Voltage Spark Tested (15kV–20kV)
Every square millimeter of fluoropolymer lining undergoes non-destructive 15,000V–20,000V dielectric spark inspection before assembly. This guarantees zero microscopic pinholes, الشقوق, or voids, ensuring corrosive acids never reach the metallic casting.
Dovetail Groove Anti-Vacuum Anchoring
Precision-machined internal dovetail grooves mechanically anchor the molten fluoropolymer under high-pressure molding. This prevents lining collapse, بثور, or delamination even under continuous full vacuum (-00.1 ميغاباسكال) والدورات الحرارية.
100% Virgin Imported PFA / FEP Resins
We exclusively mold high-density virgin fluoropolymer resins without regrind or recycled fillers. This guarantees maximum molecular density, zero chemical permeation, and superior flex fatigue resistance against boiling acids and aggressive solvents.
Integral One-Piece Ball & Stem Core
The metallic core of the ball and stem is forged as a single unified piece before fluoropolymer encapsulation. This eliminates stem-to-ball hysteresis, prevents stem shearing under heavy breakaway torque, and ensures exact quarter-turn alignment.
Acid-Mist Proof Actuator Enclosure
The electric actuator housing features a multi-layer heavy epoxy/polyurethane finish, stainless steel exterior fasteners, and sealed IP67/IP68 enclosures. It resists severe airborne acid mist and corrosive chemical plant vapors without degradation.
Live-Loaded Class VI Bubble-Tight Sealing
Self-adjusting Belleville spring-loaded V-ring stem packings continuously compensate for seal wear and thermal expansion to eliminate toxic fugitive emissions, while precision PTFE seats provide bidirectional ANSI Class VI zero leakage.

الأسئلة الشائعة (الأسئلة الشائعة)
س1: Can DELCO electric fluorine-lined ball valves withstand full vacuum (negative pressure) الخطوط?
نعم. Unlike cheaper compression-lined valves where linings collapse under suction, DELCO utilizes precision-cast internal dovetail anchoring grooves and high-pressure molding. This mechanically locks the lining to the metallic body wall, enabling our valves to safely operate under full vacuum conditions (down to -00.1 ميغاباسكال) up to +150°C (FEP) or +180°C (PFA).
س2: How do you verify the lining is completely free of microscopic pinholes before delivery?
We enforce 100% dielectric spark testing per ASTM D5162 / HG/T 3704 standards. Every valve body and ball component is scanned with a 15,000V–20,000V high-voltage spark detector prior to final assembly. Any microscopic void or thin spot instantly triggers a spark detection alarm, ensuring only flawless liners enter our assembly line. An official Spark Test Inspection Certificate is included with your order.
س3: How is the electric actuator protected from ambient acid fumes in chemical plants?
Standard actuators often fail prematurely in acid pickling or chlor-alkali plants due to ambient airborne acid mist. DELCO electric actuators for lined valves come standard with heavy-duty anti-corrosion epoxy powder coating, stainless steel exterior fasteners, sealed IP67/IP68 terminal compartments, and internal anti-condensation space heaters to prevent acid vapor intrusion.
س4: Why does DELCO exclusively use 100% virgin fluoropolymer resin instead of recycled blends?
Recycled or blended fluoropolymer resins contain micro-impurities and degraded polymer chains that lead to micro-porosity, acid permeation, stress cracking, and shortened lifespan. DELCO utilizes only 100% virgin imported FEP and PFA raw materials with full heat traceability, guaranteeing maximum molecular density and zero chemical permeation.
