RTL series partial rotary valve electric actuator can be applied to valves that rotate 90 degrees, such as butterfly valves, ball valves, plug valves, air doors, etc. for opening, closing or adjusting valves; But also can be remotely controlled and operated locally. The driver can be widely used in industrial fields such as electric power, metallurgy, petroleum, chemical industry, food, textile, papermaking, medicine, water engineering, sewage treatment and so on.

　　There are many types of partial rotary electric actuators: outdoor type, explosion-proof type, integral type, integral adjustment type and integral explosion-proof type.

　　Power supply: single-phase 220V, three-phase 380V (50Hz), DC DC24V/48V (special order: single-phase 110V, three-phase 415V, 660V, (50Hz, 60Hz).

　　Ambient temperature: -20~+60℃ (special order -40~+70℃)

　　Relative humidity: 95%(+ 25℃)

　　Protection type: outdoor type is used in places without flammable, explosive and corrosive media. There are two kinds of flameproof products: d I and d II BT4: d I is suitable for non-mining working faces in coal mines; D II BT4 is used in factories, and it is suitable for explosive gas mixtures of T1~T4 in environmental class II A and IIB.

　　Protection grade: IP67 (special order IP68).

　　Working system: short time 10 minutes (15-60 minutes for special orders)
