The Q41F46 lined PTFE flanged ball valve uses a ball with a circular through-hole as the opening and closing member. The ball rotates with the valve stem around the centerline of the valve body to achieve valve opening and closing. Special molding technology is adopted to ensure a dense and well-formed sealing surface. Combined with V-type PTFE packing assembly, the valve achieves zero leakage. The ball and valve stem are cast as an integral piece, eliminating the possibility of the stem the pressure-containing parts due to pressure changes, fundamentally ensuring safety during use. The full plastic lining process provides resistance to strong corrosion from media. Drive Modes of Q41F46 Lined PTFE Flanged Ball Valve Lined PTFE ball valves can be classified by drive mode into manual lined PTFE ball valve, worm gear operated lined PTFE ball valve, pneumatic lined PTFE ball valve, electric lined PTFE ball valve, etc. Features of Q41F46 Lined PTFE Flanged Ball Valve 1.The ball valve with fluoroplastic lining layer has extremely high chemical stability and is suitable for any strongly corrosive chemical media. 2.The full-bore floating ball valve structure ensures zero leakage closure throughout the entire pressure range, facilitating pipeline system cleaning and maintenance. Applications of Q41F46 Lined PTFE Flanged Ball Valve The lined PTFE ball valve is professionally designed for controlling the opening and closing of various strongly corrosive media. It is widely used in industries such as petroleum, chemical, dyeing, pesticide, acid and alkali manufacturing, etc. It is currently the most ideal choice for corrosion-resistant valves. Main Lining Materials of Lined PTFE Ball Valve Perfluorinated ethylene propylene FEP (F46) Applicable media: Any organic solvents or reagents, dilute or concentrated inorganic acids, alkalis, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, etc. Operating temperature: -85 to 150°C Characteristics: Mechanical, electrical, and chemical stability are basically the same as F4, but the outstanding advantage is high impact toughness, excellent weather resistance, and radiation resistance. Polychlorotrifluoroethylene PCTEF (F3) Applicable media: Various organic solvents, inorganic corrosive liquids (oxidizing acids) Operating temperature: -195 to 120°C Characteristics: Heat resistance, electrical properties, and chemical stability are second only to F4. Mechanical strength, creep resistance, and hardness are better than F4. Polypropylene RPP Applicable media: Aqueous solutions of inorganic salts, dilute or concentrated solutions of inorganic acids and alkalis. Operating temperature: -14 to 80°C Characteristics: One of the lightest plastics. Its yield, tensile, and compressive strength, and hardness are all superior to low-pressure polyethylene. It has outstanding rigidity, good heat resistance, easy molding, and low cost. Impact resistance, flowability, and bending elasticity are improved after modification. Polyvinyl chloride (rigid) PVC Applicable media: Resistant to water, concentrated alkalis, non-oxidizing acids, aliphatic hydrocarbons, oils, ozone, etc. Operating temperature: 0 to 55°C Characteristics: High mechanical strength, excellent chemical stability and dielectric properties, good oil resistance and aging resistance, easy to weld and bond, low cost. Polytetrafluoroethylene PTFE (F4) Applicable media: Strong acids, strong alkalis, strong oxidizers, etc. Operating temperature: -200 to 180°C Characteristics: Excellent chemical stability, high heat resistance and cold resistance, very low friction coefficient, excellent self-lubricating material. However, mechanical properties are relatively low, with poor flowability and large thermal expansion. Polyvinylidene fluoride PVDF (F2) Applicable media: Resistant to most chemicals and solvents. Operating temperature: -70 to 100°C Characteristics: Tensile strength and compressive strength are better than F4. Resistant to bending, weather, radiation, light, and aging. The greatest feature is good toughness and easy molding. Polyolefin PO Applicable media: Various concentrations of acids, alkalis, salts, and certain organic solvents. Operating temperature: -58 to 80°C
