Electro hydraulic pneumatic butterfly valve
The Electro Hydraulic Pneumatic Butterfly Valve is an advanced industrial flow control valve that integrates electro-hydraulic and pneumatic drive technologies to achieve precise regulation, reliable shut-off, and automated operation in complex pipeline systems.
The valve adopts a high-performance butterfly structure with a lightweight disc design, low flow resistance, and fast response characteristics. The combined electro-hydraulic pneumatic actuation system provides powerful driving force, stable operation, and flexible control options, making it suitable for large-diameter pipelines, harsh industrial environments, and automated process systems.
Designed with high-strength materials and advanced sealing technology, the valve offers excellent corrosion resistance, pressure resistance, and long service life. It can be customized with different actuator configurations, control systems, and materials according to specific working conditions.
The valve is widely used in oil & gas, power generation, chemical processing, metallurgy, water treatment, ventilation systems, and industrial automation applications requiring reliable flow control and remote operation.
