Stainless Steel Pneumatic Butterfly Valve
Product Overview:
The Stainless Steel Pneumatic Butterfly Valve combines robust construction with precise pneumatic control. This valve features a stainless steel body for enhanced corrosion resistance and durability. It is equipped with a pneumatic actuator for reliable automation. The valve is available in both single-acting and double-acting configurations. It supports both on/off and modulating control.
Pneumatic Actuator Parameters:
– Actuator Type: Pneumatic actuator.
– Single-Acting (Spring Return): Requires air pressure to open the valve. Uses a spring to automatically close the valve when air pressure is removed.
– Double-Acting: Requires air pressure to both open and close the valve. Provides precise control over the valve position.
– 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 stainless steel for superior corrosion resistance.
– Installation Standard: Complies with ISO 5211 standards for easy installation and compatibility with various valve types.
Single-Acting Pneumatic Actuator:
– Function: Requires air pressure to open the valve. Uses a spring to automatically close the valve when the air supply is lost.
– Advantages:
– Fail-Safe Operation: Automatically returns to a preset or safe position if air pressure fails. Ideal for applications requiring automatic closure in the event of air supply loss.
– Cost-Effective: Provides 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 valve position without continuous air supply.
– Application Conditions: Suitable for applications where automatic closure is essential, such as emergency shutdown systems and safety-critical processes.
Double-Acting Pneumatic Actuator:
– Function: Requires air pressure to both open and close the valve. Offers precise control of the valve position.
– Advantages:
– Precise Control: Allows for accurate positioning and control of the valve.
– Position Holding: Maintains the valve position with a continuous air supply.
– Disadvantages:
– No Automatic Closure: Does not close automatically if the air supply fails.
– Application Conditions: Ideal for applications requiring precise control and where a continuous air supply is available.
Control Types:
– On/Off Control: Provides full opening or closing of the valve. Suitable for applications requiring simple binary control.
– Modulating Control: Allows for varying degrees of valve opening. Ideal for applications needing precise flow regulation and adjustment.
Stainless Steel Material Advantages:
– Corrosion Resistance: Stainless steel offers superior resistance to corrosion and oxidation. It withstands exposure to various chemicals and moisture without significant degradation.
– Durability: The material provides enhanced strength and durability, ensuring a longer service life even under challenging conditions.
– Maintenance: Requires minimal maintenance due to its resistance to rust and corrosion.
Media and Working Conditions:
– Media Compatibility: Suitable for handling a wide range of media, including water, air, gases, steam, and chemicals. The stainless steel construction ensures compatibility with diverse substances.
– Working Conditions: Designed to operate effectively in medium to high-pressure environments. Performs reliably across a broad temperature range and in demanding applications.
Summary:
The Stainless Steel Pneumatic Butterfly Valve offers robust construction and reliable pneumatic control. It features a stainless steel body for superior corrosion resistance. The valve is available in single-acting and double-acting actuator configurations, supporting both on/off and modulating control. Single-acting actuators provide a fail-safe solution with automatic closure, while double-acting actuators offer precise control. This valve is versatile and durable, making it ideal for a wide range of industrial applications.
