Electric eccentric hemispherical valve
The Electric Eccentric Hemispherical Valve integrates a high-performance electric actuator with an eccentric hemispherical sealing mechanism. Designed for automated process control, it offers excellent sealing performance, low operating torque, self-cleaning capability, and extended service life. Ideal for slurry, wastewater, pulp, ash, and particle-laden industrial media.
Electric eccentric hemispherical valve
The Electric Eccentric Hemispherical Valve is a high-performance automated control valve engineered for severe-service applications. Its unique eccentric hemispherical disc design minimizes friction between sealing surfaces during operation, reducing wear and significantly extending valve lifespan.
Combined with an intelligent electric actuator, the valve provides accurate positioning, remote operation, and reliable automated flow control. The self-cleaning sealing action ensures dependable performance in abrasive, viscous, fibrous, and solid-particle media. It is widely used in mining, metallurgy, power generation, wastewater treatment, pulp & paper, and chemical industries.
