Pneumatic Wafer Butterfly Valve
Product Overview:
The Pneumatic Wafer Butterfly Valve combines efficient fluid control with reliable pneumatic actuation. This valve features a wafer-style design. It is ideal for compact installations and space-constrained environments. The valve integrates a pneumatic actuator for precise control and automation. It is available in both single-acting and double-acting configurations. The valve can be customized for on/off or modulating control.
Pneumatic Actuator Parameters:
– Actuator Type: Pneumatic actuator
– Single-Acting (Spring Return): Requires air pressure to open the valve. Uses a spring mechanism to automatically return the valve to a preset position when air pressure is removed.
– Double-Acting: Requires air pressure to both open and close the valve. Provides precise control over valve position.
– Operating Pressure: Effective range of 3 to 8 bar (43 to 116 psi).
– Temperature Range: Operates within -20°C to 80°C (-4°F to 176°F).
– Material: Made from durable aluminum or stainless steel.
– Installation Standard: Complies with ISO 5211 standards for compatibility and ease of installation.
Single-Acting Pneumatic Wafer Butterfly Valve:
– Function: Requires air pressure to open the valve. Uses a spring to automatically close the valve when air pressure is removed.
– Advantages:
– Fail-Safe Operation: Automatically returns to a preset or safe position if the air supply fails. Ideal for safety-critical applications.
– Cost-Effective: Provides a simple and economical solution for applications requiring automatic closure.
– 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. Examples include emergency shutdown systems and safety-critical processes.
Double-Acting Pneumatic Wafer Butterfly Valve:
– Function: Requires air pressure to both open and close the valve. Offers precise control over 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 automatically close if the air supply fails.
– Application Conditions: Ideal for applications requiring precise control. Suitable for situations where a continuous air supply is available for maintaining valve position.
Control Types:
– On/Off Control: Provides full opening or closing of the flow. Suitable for applications requiring simple binary control.
– Modulating Control: Allows for varying degrees of valve opening. Suitable for applications needing precise flow regulation and adjustment.
Wafer Connection Advantages:
– Compact Design: The wafer-style connection allows for a space-efficient design. Ideal for installations with limited space.
– Cost-Effective: Generally more affordable compared to flanged connections. Requires fewer materials and has a simpler design.
– Ease of Installation: Simplifies installation and alignment within the pipeline. Reduces installation time and effort.
– Versatility: Compatible with a wide range of pipeline sizes and types. Adaptable to various standards and systems.
Summary:
The Pneumatic Wafer Butterfly Valve offers efficient fluid control with pneumatic actuation. It is available in single-acting and double-acting configurations. Single-acting actuators provide a fail-safe solution with automatic closure. Double-acting actuators offer precise control and position holding. The wafer connection provides a compact, cost-effective, and easy-to-install solution. It is suitable for a variety of industrial applications.
