Pneumatic Flange Butterfly Valve
Product Overview:
The Pneumatic Flange Butterfly Valve is designed for efficient and reliable fluid control in industrial applications. It integrates a pneumatic actuator for precise operation. The valve features a flange connection for robust and secure installation. It is available in both single-acting and double-acting configurations. Additionally, it can be customized for on/off or modulating control.
Pneumatic Actuator Parameters:
– Actuator Type: Pneumatic actuator, available in single-acting or double-acting versions.
– Operating Pressure: Effective range is 3 to 8 bar (43 to 116 psi).
– Temperature Range: Operates within -20°C to 80°C (-4°F to 176°F).
– Material: Constructed from durable aluminum or stainless steel.
– Installation Standard: Complies with ISO 5211 standards for compatibility and ease of installation.
Single-Acting Pneumatic Flange Butterfly Valve:
– Function: Requires air pressure to open the valve. It uses a spring mechanism to automatically close the valve when the air supply is lost.
– Advantages:
– Fail-Safe Operation: Automatically returns to a preset or safe position if the air supply fails.
– Cost-Effective: Provides a simple and economical solution for safety-critical applications.
– Disadvantages:
– Lower Control Accuracy: Less precise compared to double-acting actuators.
– Position Holding: Cannot hold the valve position without continuous air supply.
– Application Conditions: Ideal for safety-critical systems where automatic closure is needed, such as emergency shutdowns. Suitable for applications with intermittent pneumatic operation.
Double-Acting Pneumatic Flange Butterfly Valve:
– Function: Requires air pressure to both open and close the valve. Offers precise control of the valve position.
– Advantages:
– Accurate Control: Provides precise positioning and control of the valve.
– Position Holding: Maintains valve position with continuous air supply.
– Disadvantages:
– No Automatic Closure: Does not automatically close if the air supply fails.
– Application Conditions: Suitable for applications requiring precise control and consistent performance. Ideal where continuous air supply is available for maintaining valve position.
Control Types:
– On/Off Control: The valve is used for fully opening or closing the flow. Ideal for applications requiring simple binary control.
– Modulating Control: Allows varying degrees of valve opening. Suitable for applications needing precise flow regulation and adjustment.
Flange Connection Advantages:
– Robust and Secure: Flange connections provide a strong, leak-proof seal. This enhances the valve’s stability and durability.
– Easy Installation: Flanged connections simplify installation and maintenance. They allow for easy alignment and secure attachment to pipelines.
– Versatility: Suitable for a wide range of pipeline sizes and types. Flange connections accommodate different flange standards, making the valve adaptable to various systems.
Summary:
The Pneumatic Flange Butterfly Valve offers efficient and reliable fluid control with the integration of a pneumatic actuator. It is available in single-acting and double-acting configurations and supports both on/off and modulating control. Single-acting actuators provide a cost-effective, fail-safe option, while double-acting actuators offer precise control and position holding. The flange connection ensures robust, leak-proof installation and easy maintenance. This valve is well-suited for industrial applications requiring reliable performance and adaptability.
