Pneumatic Control Butterfly Valve
Product Overview:
The pneumatic control butterfly valve is designed for precise control and reliable operation in various industrial applications. It integrates a pneumatic actuator for efficient fluid flow management. This valve comes in both single-acting and double-acting configurations. It can be customized for either on/off control or modulating control.
Pneumatic Actuator Parameters:
– Actuator Type: Pneumatic actuator (single-acting or double-acting).
– Operating Pressure: Ranges from 3 to 8 bar (43 to 116 psi).
– Temperature Range: Operates from -20°C to 80°C (-4°F to 176°F).
– Material: Made of durable aluminum or stainless steel.
– Installation Standard: Conforms to ISO 5211 for compatibility and ease of installation.
Single-Acting Pneumatic Control Butterfly Valve:
– Function: Uses air pressure to open the valve. A spring mechanism closes the valve automatically 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: Offers a simpler and more economical solution for safety-critical applications.
– Disadvantages:
– Lower Control Accuracy: Less precise compared to double-acting actuators.
– Position Holding: Cannot maintain the valve position without continuous air supply.
– Application Conditions: Ideal for environments requiring automatic fail-safe closure, such as emergency shutdown systems. Suitable for applications with less frequent pneumatic operation.
Double-Acting Pneumatic Control Butterfly Valve:
– Function: Requires air pressure to both open and close the valve. Provides precise control of the valve position.
– Advantages:
– Accurate Control: Allows for precise positioning and control of the valve.
– Position Holding: Maintains the valve position as long as the air supply is continuous.
– Disadvantages:
– No Automatic Closure: Does not automatically close if the air supply fails.
– Application Conditions: Suitable for applications needing precise control and position holding. Ideal where continuous air supply is available. Suitable for processes requiring fine adjustments and consistent performance.
Control Types:
– On/Off Control: The valve is used for fully opening or fully closing the flow. This is ideal for simple applications where binary control is sufficient.
– Modulating Control: The valve allows varying degrees of opening. It provides precise control of flow rates. This is suitable for applications requiring fine adjustment and regulation of flow.
Summary:
The pneumatic control butterfly valve is designed for both on/off and modulating control in various industrial settings. It is available in single-acting and double-acting configurations, offering flexibility based on application needs. Single-acting actuators provide a cost-effective fail-safe option with automatic closure in case of air supply failure. Double-acting actuators offer precise control and position holding with continuous air supply. This valve handles a range of media and operating conditions effectively.
