Product Overview

The Hydraulic Actuated Slow Closed Butterfly Valve is designed for controlling the flow of liquids, gases, or slurries in a wide range of industrial applications. With its hydraulic actuator, this valve offers a slow closing function, which ensures a smooth and controlled closure, minimizing water hammer and reducing the risk of damage to the piping system. It is ideal for use in systems where a gradual shutoff is required to avoid sudden pressure surges.

The valve features a robust, durable construction, making it suitable for high-pressure applications. Its precision-engineered butterfly design allows for reliable flow regulation and tight sealing performance. The hydraulic actuator enables precise control over the opening and closing time, ensuring optimal operational efficiency. With excellent corrosion resistance and a reliable sealing mechanism, this valve is perfect for demanding environments in industries such as water treatment, power generation, and chemical processing.

Product Features

Fast Closing Time: Achieves a quick closing time of up to 0.5 seconds, ensuring emergency shutoff with high reliability.
Triple-Eccentric Metal Sealing Structure: Provides smooth and flexible opening and closing with zero leakage due to the advanced sealing technology.
Dual-Eccentric Soft Sealing Structure: For normal temperature media, this cost-effective soft seal structure ensures reliable sealing performance.
End-of-Close Buffer: Effectively prevents valve impact caused by inertia at the end of closure, protecting the system from damage.
Quick Close Options: Can utilize either a spring or an accumulator to achieve rapid closing, both methods ensuring safety and reliability.
