Heavy Duty IP68 Modulating Electric Rotary Valve Actuator Explosion Proof

DINKONDA GLOBAL Power Plants Special 2SA8.1 Series IP68 Operation Mode S2 Explosion Proof Intelligent Multi Rotary Electric Valve Actuators

Product Overview
Intelligent electric actuators are driving devices for various electric valves in open-loop/closed-loop control systems, used for opening, closing, and automatic control of valves. The 2SA8 series multi turn intelligent electric actuator is suitable for gate valves, globe valves, diaphragm valves, and various regulating valves. The 2SQ8 (2SJ8) series partial turn (angular stroke) intelligent electric actuator is a derivative product of the 2SA8 series products, suitable for partial turn and angular stroke valves such as disc valves, ball valves, and air door baffles. The 2SB8 series is an electric actuator that outputs thrust, and can accurately act according to control instructions. It is an essential driving device for remote control, centralized control, and automatic control of valves.
This series of products can be used not only in power plants, but also in petrochemicals, metallurgy, mining, public utilities, and more.
