Product Introduction: Electric Butterfly Valve
The Electric Butterfly Valve is a versatile and reliable control device used in various industrial applications. This valve integrates an electric actuator with a butterfly valve, providing precise and automated control over fluid flow. It comes in different sealing options, including hard-seal and soft-seal types. The valve can be connected through methods like flange, wafer, and butt-weld connections.
Detailed Parameters of Electric Actuators
– Power Supply: Supports multiple options like AC 220V, 380V, or DC 24V. These options cater to different application needs.
– Control Mode: Offers switch control for full open/close operations. It also has regulation control for precise valve positioning and flow adjustment.
– Protection Level: Typically rated IP65 or higher. This ensures resistance against dust and water, making it suitable for harsh environments.
– Output Torque: Ranges from tens to thousands of Newton meters, depending on valve size and pressure requirements.
– Operating Speed: The opening and closing speed is adjustable. It usually ranges from a few seconds to several tens of seconds.
– Position Feedback: Equipped with high-precision sensors. These sensors provide real-time valve position feedback, ensuring accurate control.
Butterfly Valve Features
Hard-Seal Butterfly Valve
– Characteristics: It has a metal sealing surface. This provides resistance to high temperature, high pressure, and wear. It is reliable in challenging environments.
– Applicable Media: Suitable for high-temperature steam, hot oil, gas, and corrosive chemical media.
– Working Conditions: Commonly used in high-pressure and high-temperature systems in industries like petrochemical, power generation, and metallurgy.
Soft-Seal Butterfly Valve
– Characteristics: It uses elastic materials like rubber or PTFE for the sealing surface. This ensures zero leakage and low operating torque, resulting in smooth and flexible operation.
– Applicable Media: Best suited for non-corrosive or mildly corrosive fluids such as water, air, and oil.
– Working Conditions: Widely used in urban water supply, sewage treatment, HVAC systems, and other light industrial applications.
Connection Methods
– Flange Connection: Provides a strong, secure attachment between the valve and piping. It is suitable for high-pressure applications.
– Wafer Connection: This is a cost-effective and space-saving option. It is easily installed between two flanges, making it ideal for systems with limited space.
– Butt-Weld Connection: Offers a permanent, leak-free connection. It is particularly suitable for high-pressure environments.
Usage Media and Working Conditions
– Flange Connection: Ideal for high-pressure, high-temperature environments. It handles steam, oil, and gas.
– Wafer Connection: Suitable for moderate-pressure systems. It is commonly used in water treatment, HVAC, and gas pipelines.
– Butt-Weld Connection: Best for high-pressure applications requiring a secure and long-lasting connection. It is used in power plants and chemical processing.
Summary
The Electric Butterfly Valve is a high-performance solution. It integrates advanced electric actuators with robust butterfly valve designs. With options for both hard-seal and soft-seal configurations, and multiple connection methods, it is adaptable to a wide range of industrial applications. Whether managing high-temperature steam or controlling the flow of water in urban systems, this valve offers precision, reliability, and efficiency.
