Comparative Analysis of Electric and Pneumatic Eccentric Ball Valves
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, inclusa una bassa forza di apertura, chiusura efficace per superare gli ostacoli alla scalabilità, ed eccellenti prestazioni di tenuta. It is also wear-resistant. Made of corrosion-resistant materials, this valve is widely used in conveying water, vapore, liquami, fabbricazione della carta, prodotti petrolchimici, gas naturale, soluzioni, and slurries—ideal equipment for transporting dusty gases, fluidi particolati, e solidi in polvere. Electric operation makes it convenient for automated management and remote control. With an electric signal device, può essere utilizzato per il funzionamento automatizzato e il controllo centralizzato.
The pneumatic eccentric ball valve relies on a rotating valve chain to open or close the valve. Le valvole a sfera sono facili da usare, compatto, and can be made in large diameters. They offer reliable sealing, struttura semplice, and easy maintenance. The sealing surface and the ball are constantly in a closed state, rendendoli meno suscettibili all’erosione da parte del mezzo. This product is equipped with a single/double cylinder series two-action partial rotary valve pneumatic device. Controllato da un'elettrovalvola, può ottenere il funzionamento automatico remoto.
The pneumatic eccentric ball valve utilizes an eccentric valve body, sfera eccentrica, sede della valvola, and valve stem. As they rotate, they automatically center themselves along a common trajectory, serrare ulteriormente in fase di chiusura per ottenere una perfetta tenuta. 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. Il materiale elastico non metallico è incorporato nel sedile metallico, fornendo un'eccellente protezione per la superficie metallica del sedile. This product is particularly suitable for media in the steel, aluminum, fibra, piccole particelle solide, polpa, cenere di carbone, 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, distribuzione, e cambiando la direzione del flusso dei 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.
