Pneumatic Actuator Butterfly Valve
Product Overview:
The Pneumatic Actuator Butterfly Valve combines the efficiency of a butterfly valve with pneumatic actuation. It is designed for automated flow control in industrial environments. This valve offers reliable performance and easy integration into automated systems.
Pneumatic Actuator Parameters:
– Actuator Type: Available as double-acting or spring-return.
– Pressure Range: Operates within 3-8 bar (43-116 psi).
– Temperature Range: Suitable for temperatures from -20°C to 80°C (-4°F to 176°F).
– Actuator Material: Constructed from aluminum or stainless steel.
– Mounting: Complies with ISO 5211 standards for easy installation and replacement.
Advantages of Pneumatic Actuation:
– Fast Response: Provides quick and precise control, improving system responsiveness.
– Safety: Safer in explosive or flammable environments, as it does not require electrical power at the valve site.
– Durability: Robust and capable of handling harsh operating conditions.
– Cost-Effective: Generally less expensive than electric actuators and requires less maintenance.
Disadvantages of Pneumatic Actuation:
– Compressed Air Supply: Requires a reliable and consistent compressed air supply.
– Energy Consumption: Less energy-efficient compared to electric actuators.
– Noise: Can generate more noise during operation compared to electric actuators.
Butterfly Valve Structure and Sealing:
– Design: Features a wafer-style or lug-style design with a central disc for flow control. The pneumatic actuator operates the disc to open or close the valve.
– Sealing: Equipped with various sealing options, including soft seals (EPDM, PTFE) or hard seals (metal). The choice depends on the media and operating conditions.
Media and Operating Conditions:
– Media Compatibility: Suitable for a wide range of media, such as water, air, steam, gases, and various chemicals. Seal material should match the media type and temperature.
– Operating Conditions: Designed for medium to high-pressure applications. The valve maintains sealing integrity and performance under varying temperatures. Ensure compatibility between the actuator, valve materials, and operating environment.
Summary:
The Pneumatic Actuator Butterfly Valve is ideal for automated flow control. It offers fast, precise control and robust performance. Advantages include safety and durability. However, it requires a consistent compressed air supply and is less energy-efficient. The valve is versatile, with options for different sealing materials and suitable for various media and conditions.
