Double Acting Pneumatic Actuator Butterfly Valve
Product Overview:
The Double Acting Pneumatic Actuator Butterfly Valve is designed for precision and reliability. It features a double-acting pneumatic actuator, which is ideal for various industrial applications. This actuator ensures consistent performance. It is suitable for handling a wide range of media under different operating conditions.
Pneumatic Actuator Parameters:
– Actuator Type: The valve uses a double-acting pneumatic actuator. This actuator requires air pressure to both open and close the valve. It provides full control over the valve’s movement in both directions.
– Operating Pressure: The actuator functions effectively within a pressure range of 3 to 8 bar (43 to 116 psi). This allows reliable performance under different conditions.
– Temperature Range: The actuator operates in temperatures ranging from -20°C to 80°C (-4°F to 176°F). This ensures consistent operation in various environments.
– Material: The actuator is typically made from high-quality aluminum or stainless steel. These materials offer durability and corrosion resistance.
– Mounting Standard: The actuator conforms to ISO 5211 standards. This standardization facilitates easy installation and replacement.
Differences Between Double Acting and Single Acting Actuators:
– Double Acting Actuator:
– Functionality: Air pressure is required for both opening and closing the valve. The actuator allows precise control in both directions. The valve stays in its last position if the air supply is cut off.
– Advantages: Provides consistent and precise control. Suitable for applications where the valve needs to stay in the last position during a power loss.
– Disadvantages: Requires a constant air supply, which can increase operational costs.
– Single Acting Actuator (Spring-Return):
– Functionality: Air pressure moves the valve in one direction. A spring mechanism returns the valve to its original position when the air supply is cut off.
– Advantages: Ideal for safety applications. The valve automatically returns to a fail-safe position during a power loss or air failure.
– Disadvantages: Less control over the valve position. Relies on the spring mechanism to return to the default state.
Application Conditions:
– Media Compatibility: The valve handles a wide range of media. This includes water, air, gases, steam, and various chemicals. It is suitable for industries such as oil and gas, chemical processing, water treatment, and power generation.
– Operating Conditions: The valve performs reliably in medium to high-pressure environments. It operates effectively under varying temperatures. The valve’s robust construction ensures long-term performance in demanding industrial settings.
Summary:
The Double Acting Pneumatic Actuator Butterfly Valve offers precise control and reliable operation. Its double-acting actuator provides consistent control in both directions. Compared to single-acting actuators, it offers more precise control but requires a constant air supply. The valve is compatible with a wide range of media and performs well under various operating conditions. This makes it a versatile and dependable choice for industrial flow control systems.
