What is an Electric Actuated Ductile Iron PTFE Lined Wafer Butterfly Valve Used For?
Electric actuated ductile iron PTFE lined wafer butterfly valves are designed for handling aggressive and corrosive fluids in various industrial applications. The PTFE lining provides excellent chemical resistance, making these valves ideal for chemical processing, pharmaceutical production, petrochemical industries, and food and beverage applications. The ductile iron body offers superior strength and durability, while the wafer design allows for easy installation between flanges, reducing space requirements and simplifying maintenance. The electric actuator ensures precise, automated control of the valve, enhancing operational efficiency and allowing for remote operation.
Key Features
Material: The valve body is constructed from durable ductile iron, ensuring long-term strength and reliability.
Disc and Liner: The disc is stainless steel coated with PTFE, and the liner is made of PTFE, offering excellent chemical resistance and durability.
Temperature Range: Operates effectively within a wide temperature range of -40°C to +200°C.
Pressure Rating: Can handle a maximum working pressure of 16 bar, providing robust performance under moderate pressure conditions.
Flange Compatibility: The valve features a wafer pattern flange compatible with PN6/10/16, ANSI150 and BS 10 Table D/E, ensuring secure, leak-free connections and easy integration into existing pipeline systems.
Compatibility: Fully compatible with standard market actuators due to the ISO 5211 flange.
Voltage Range: Multi voltage operation supports 24-240V DC/V AC 50/60Hz, offering flexibility for integration into various electrical systems.
Visual Operation Control (VCO): Multicoloured LED light provides continuous status feedback, allowing users to easily monitor the actuator’s operation.
Electronic Torque Limiter (ETS): Prevents damage from over-torquing and ensures long-term reliability with auto gearbox relaxing.
Failsafe and Modulating Options: Can be configured for fail-safe and modulating operations, enhancing functionality and adaptability to different operational requirements.
Brushless Motor: Reduces maintenance, improves efficiency, and minimises heat and noise, ensuring robust and efficient performance.
Manual Override (MO): Declutchable manual emergency control allows manual operation if needed.
Temperature Control (ATC): Thermostatically controlled 3.5W heater maintains the interior temperature to prevent damage from condensation.
