explosion-proof electric three eccentric butterfly valve

产品概述：

The Explosion-Proof Electric Three-Eccentric Butterfly Valve combines advanced three-eccentric design with explosion-proof electric actuation to provide secure, reliable, and efficient flow control in hazardous environments. This valve is designed to handle extreme conditions where safety, high performance, and durability are critical. The three-eccentric geometry ensures tight sealing with minimal wear, making it suitable for industries dealing with flammable gases, chemicals, or environments prone to explosive risks.

This valve is engineered to meet international explosion-proof standards, making it ideal for use in explosive atmospheres where potential risks of fire or explosion must be mitigated. It is typically used in industries like petrochemical, oil & gas, chemical processing, and mining.

主要功能

Explosion-Proof Electric Actuation: The valve is equipped with an explosion-proof electric actuator that ensures safe operation in hazardous environments, reducing the risk of ignition caused by electrical sparks. The actuator is designed to withstand harsh conditions and complies with stringent explosion-proof standards (e.g., Exd II BT4).

Three-Eccentric Design: The valve employs a three-eccentric (or triple-offset) design, which provides superior sealing performance. This design minimizes friction between the valve disc and the seat, ensuring smooth operation and a longer service life while providing tight shut-off.

Leakage-Free Performance: The three-eccentric design, combined with high-performance sealing materials, ensures virtually zero leakage under full operating pressure, even with corrosive and aggressive fluids.

High-Temperature and High-Pressure Resistance: The valve is capable of handling a wide range of temperatures (from -50°C to +450°C) and pressures (up to PN40), making it suitable for demanding applications involving steam, hot gases, or high-pressure fluids.

Durability in Harsh Environments: Constructed from high-strength materials such as carbon steel, stainless steel, or alloy steel, the valve is designed to withstand the harshest industrial conditions, including exposure to high temperatures, chemicals, and abrasive materials.

Long Service Life: The unique design of the valve, combined with premium sealing materials such as PTFE, graphite, or metal seals, ensures extended performance with minimal maintenance.

Remote Control and Automation: The electric actuator enables easy integration into automated systems, allowing for remote operation, monitoring, and control. It also supports modulating control for precise flow regulation.
