Revised Product Introduction: Electric Hard Seal Butterfly Valve
Overview:
The Electric Hard Seal Butterfly Valve is a high-performance control valve. It integrates a reliable electric actuator with a durable butterfly valve design. This valve offers precise fluid control and is ideal for demanding applications. It excels in high-temperature, high-pressure, and corrosive environments.
Detailed Parameters of Electric Actuator
– Power Supply: The actuator supports multiple options, including AC 220V, 380V, and DC 24V. This flexibility suits various industrial settings.
– Control Mode: Available in switch control and regulation control modes. The switch type provides full-open or full-close operations. The regulation type allows precise control of valve opening for linear flow regulation.
– Protection Level: Typically rated IP65 or higher. This ensures protection against dust and water, making it suitable for harsh environments.
– Output Torque: The actuator offers a wide torque range, from tens to thousands of Newton-meters. This range matches different valve specifications and pressures.
– Operating Speed: The opening and closing speeds are adjustable. They range from a few seconds to tens of seconds to meet different process needs.
– Position Feedback: High-precision sensors provide real-time feedback on valve position. This ensures accurate and reliable control.
Hard Seal Butterfly Valve Structure and Features
The Hard Seal Butterfly Valve features a triple eccentric structure for enhanced sealing and durability. This design includes three key elements:
- Triple Eccentric Design:
– First Eccentricity: The shaft is offset from the valve body’s centerline. This reduces friction during operation.
– Second Eccentricity: The shaft is also offset from the valve seat’s centerline. This design prevents rubbing of the sealing surfaces, reducing wear.
– Third Eccentricity: The disc and seat axes are inclined relative to each other. This ensures a zero-leakage metal-to-metal seal with minimal contact.
- Features:
– High Temperature and Pressure Resistance: The metal sealing surface withstands extreme temperatures and pressures.
– Wear Resistance: The construction is robust, offering long-term reliability with minimal maintenance.
– Corrosion Resistance: The sealing materials resist corrosion, even in aggressive media.
Connection Methods
– Flange Connection: Provides a secure and stable connection. It is ideal for installations where disassembly may be required.
– Wafer Connection: Compact and lightweight, it is perfect for space-constrained applications. It simplifies installation between existing flanges.
– Butt-Weld Connection: Ensures a permanent, leak-proof connection. It is ideal for high-pressure applications requiring a seamless pipeline.
Medium and Working Conditions
– Suitable Media:
– High-Temperature Steam and Hot Oil: Ideal for extreme heat applications.
– Chemical Media: Resistant to corrosive substances, suitable for chemical processing.
– Gas: Handles various gases under high pressure.
– Working Conditions:
– Temperature Range: Suitable for temperatures from -40°C to 425°C, depending on materials.
– Pressure Range: Designed for high pressures, often up to 1500 LB or more.
– Environment: Suitable for indoor and outdoor installations, even in harsh conditions with high humidity, corrosive atmospheres, or extreme temperatures.
Summary
The Electric Hard Seal Butterfly Valve is ideal for industries needing precise control in tough environments. Its triple eccentric structure ensures zero leakage and minimal wear. With various connection options, this valve is versatile and reliable for many applications. The advanced electric actuator technology enhances performance, making it essential for industrial control systems.
