Vergleichende Analyse elektrischer und pneumatischer Exzenterkugelhähne
Both electric and pneumatic eccentric ball valves are suitable for applications with stringent requirements, such as wastewater treatment, pulp and alumina processing, and urban heating systems. They are also suitable for control in power plants, hydraulic slag removal, or gaseous pipelines.
Features of the electric eccentric ball valve:
A practical ball valve with a 90° rotating electric actuator, making it easier for users to operate and enabling remote automated operation. This expands the application range of ball valves, especially in harsh environments where manual operation or normally open operation is inconvenient. When combined with automated computer operation, the double eccentric ball valve with an electric actuator represents a new innovation. This valve possesses all the advantages of a double eccentric ball valve, including low opening force, effective closure to overcome scaling obstacles, and excellent sealing performance. It is also wear-resistant. Made of corrosion-resistant materials, this valve is widely used in conveying water, Dampf, Abwasser, Papierherstellung, petrochemicals, Erdgas, solutions, and slurries—ideal equipment for transporting dusty gases, particulate fluids, and powdered solids. Electric operation makes it convenient for automated management and remote control. With an electric signal device, it can be used for automated operation and centralized control.
The pneumatic eccentric ball valve relies on a rotating valve chain to open or close the valve. Ball valves are easy to operate, compact, and can be made in large diameters. They offer reliable sealing, einfache Struktur, und einfache Wartung. The sealing surface and the ball are constantly in a closed state, making them less susceptible to erosion by the medium. This product is equipped with a single/double cylinder series two-action partial rotary valve pneumatic device. Controlled by a solenoid valve, it can achieve remote automatic operation.
The pneumatic eccentric ball valve utilizes an eccentric valve body, Exzentrische Kugel, valve seat, and valve stem. As they rotate, they automatically center themselves along a common trajectory, Beim Schließen noch weiter anziehen, um eine perfekte Abdichtung zu erreichen. The valve’s ball and seat are completely separated, eliminating wear on the sealing ring and overcoming the problem of constant wear between the valve seat and the ball’s sealing surface in traditional ball valves. In den Metallsitz ist nichtmetallisches elastisches Material eingebettet, Bietet hervorragenden Schutz für die Metalloberfläche des Sitzes. This product is particularly suitable for media in the steel, aluminum, Faser, kleine feste Partikel, Fruchtfleisch, Kohlenasche, and petroleum gas industries.
Pneumatic eccentric ball valves and eccentric ball valves belong to the same type of valve, differing in their power source. Eccentric ball valves open and close by rotating the ball around the valve body’s centerline. Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media. Two-piece and three-piece ball valves are new types of valves that have been widely adopted in recent years, and pneumatic eccentric ball valves are increasingly being used in various industries.
