Air Actuated Butterfly Valve
Product Overview:
The Air Actuated Butterfly Valve combines the efficiency of a butterfly valve with pneumatic actuation. It is designed for various industrial applications. This valve provides reliable and precise control of flow and pressure in automated systems.
Pneumatic Actuator Parameters:
– Actuator Type: Available in double-acting and spring-return configurations.
– Pressure Range: Operates effectively within 3-8 bar (43-116 psi).
– Temperature Range: Suitable for temperatures from -20°C to 80°C (-4°F to 176°F).
– Material: Actuators are typically made from aluminum or stainless steel for durability.
– Mounting Standard: Complies with ISO 5211 for easy installation and replacement.
Advantages of Pneumatic Actuation:
– Rapid Response: Provides quick and accurate valve movement. This enhances control over processes.
– Safety: Operates without electrical power at the valve site. This reduces risk in hazardous environments.
– Durability: Designed to withstand harsh conditions and heavy-duty applications.
– Cost-Effective: Generally less expensive and requires less maintenance compared to electric actuators.
Disadvantages of Pneumatic Actuation:
– Compressed Air Dependency: Requires a consistent and reliable source of compressed air.
– Energy Consumption: Typically less energy-efficient compared to electric actuators.
– Noise: Can generate operational noise, which may be higher than that of electric actuators.
Butterfly Valve Structure and Sealing:
– Design: Features a wafer or lug style design with a central disc for flow regulation. The air actuator operates the disc to open or close the valve.
– Sealing: Comes with various sealing options including soft seals (EPDM, PTFE) and hard seals (metal). The choice depends on the media and operating conditions.
Media and Operating Conditions:
– Media Compatibility: Suitable for use with a broad range of media including water, air, steam, gases, and various chemicals. Select seal materials compatible with the specific media and temperature requirements.
– Operating Conditions: Designed for medium to high-pressure applications. Maintains performance and sealing integrity under varying temperatures and pressures. Ensure compatibility between the actuator, valve materials, and operating environment.
Summary:
The Air Actuated Butterfly Valve is ideal for automated flow control in industrial settings. It offers quick and precise control, robust performance, and safety in hazardous environments. While it requires a reliable compressed air supply and can be less energy-efficient, it is cost-effective and durable. Suitable for various media and conditions, it provides versatile and reliable operation.
