    FAQs

    What is PTFE lined butterfly valve?

    A PTFE (Polytetrafluoroethylene) Lined Butterfly Valve is a robust and innovative solution within the valve manufacturing industry, specifically designed to manage corrosive and harsh fluid flow in various pipeline systems.

    The defining feature of this valve is its PTFE lining, a high-performance fluoropolymer known for its exceptional chemical resistance, low friction coefficient, and excellent temperature endurance. This lining forms a protective barrier between the valve’s metal components and the passing fluid, effectively shielding the valve from potential corrosion or damage due to aggressive media.

    At the heart of this valve lies a disc-shaped closure mechanism, which rotates around a central axis to control the fluid passage. The disc’s operation is facilitated by either a manual lever or an automated actuator, ensuring precision control over the valve’s open and close process.

    The difference between PTFE lined butterfly valve and rubber lined butterfly valve?

    A PTFE Lined Butterfly Valve and a Rubber Lined Butterfly Valve are both pivotal assets in the valve manufacturing industry, each specifically engineered to control fluid flow within various pipeline systems. However, the primary distinction between these two lies in their respective lining materials and the applications they are best suited for.

    A PTFE (Polytetrafluoroethylene) Lined Butterfly Valve is characterized by its high-performance fluoropolymer lining, known for its exceptional chemical resistance, low friction coefficient, and excellent temperature endurance. This lining forms an effective shield between the valve’s metal components and the flowing media, offering superior protection against potential corrosion or damage from aggressive substances. The PTFE Lined Butterfly Valve is ideal for applications involving corrosive chemicals, acids, and other harsh substances, where its durability and operational efficiency shine.

    Contrastingly, a Rubber Lined Butterfly Valve features a resilient rubber lining, renowned for its flexibility and wear resistance. This lining provides a tight seal and dampens vibration, making it particularly suitable for handling abrasive slurries, water, air, and other non-corrosive media. The rubber lining also contributes to a reduced torque requirement, enabling easier operation and potentially extending the valve’s service life.

    What media conditions are PTFE lined butterfly valves used for?

    PTFE Lined Butterfly Valves, the paragons of robustness and efficiency in our valve portfolio, are meticulously engineered for controlling fluid flow under challenging media conditions. Their defining feature, the PTFE (Polytetrafluoroethylene) lining, is a high-performance fluoropolymer celebrated for its exceptional chemical resistance, low friction coefficient, and superior temperature endurance.

    These valves are specifically designed to tackle aggressive and corrosive media conditions. The PTFE lining forms a protective barrier between the valve’s metal components and the passing fluid, effectively safeguarding the valve against potential corrosion or damage. This makes them ideal for applications involving a wide range of corrosive chemicals, including strong acids, alkalis, solvents, and other harsh substances.

    Moreover, with their excellent temperature resilience, PTFE Lined Butterfly Valves can comfortably handle media with elevated temperatures, further expanding their application scope. Their durability and operational efficiency make them an indispensable asset in industries such as chemical processing, petrochemical, pharmaceutical, power generation, and water treatment, among others.

    In summary, PTFE Lined Butterfly Valves are the optimal choice for managing fluid flow under adverse media conditions, especially when dealing with corrosive substances and high temperatures. As an industry leader in valve manufacturing, we confidently offer these high-performance valves, reinforcing our commitment to quality, innovation, and technical excellence.

    working principle

    Pneumatic actuator working principle: Double acting Double acting working (Counterclockwise) Compressed air to Port 2 forces the pistons outwards, causing the output shaft to turn counterclockwise, while the air is being exhausted from Port 4.(Clockwise) Air to Port 4 forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port 2. Single actingSingle acting working (Clockwise) Loss of air pressure, the stored energy in the springs forces the pistons inwards,the pinion turns clockwise, while air is being exhausted from Port 4. pneumatic actuator
