Description

Summary

LQ valve actuators are the new generation of our company and can be used for driving and controlling the butterfly valves, ball valves, plug valves (part - turn valves with 90°movement). The actuators can be either remotely controlled, or locally control.

They are widely used in the fields such as oil, chemistry, power generation, water treatment, paper making. etc

The protection class is IP67,and the explosion proof class is dBT4(with letters of Ex)

Characteristics

1. Housing: Hard anodized Aluminum casting and external epoxy power coated against severe industrial environment.

2. Gearing: Precisely machined double worm gear C/W minimum black - lash, low noise, high output torque.

3. Self - locking: Provided double worm gearing to keep position of valve unchanged against reverse torque from valve.

4. Motor: Specially designed and induction motor to generate high starting torque and high efficiency equipped with thermal protector to prevent damage from over heating. Insulation class F.

5. External mechanical stopper: Prevents over run of travel angle when limit switch fails.

6. Torque switches: Protect actuator from damage caused by overload from the driven valve over the whole travel,1 each for open/close.

7. Limit switches: Directly engaged with driving shaft to set accurate position of valve, supplying a dry contact signal.

8. Terminal: Spring loaded push type terminal for tight wiring connection under severe vibration.

9. Space heater: Anti - condensation.

10. Manual override: Auto/Manual switchable lever and handwheel engagement for emergency manual operation. Drive force automatically resorted by motor start, unless lever padlocked to prevent this occurring.

11. Handwheel: Manual operated, turn on - off valve directly when power off.

Electrical characteristics

1. Automatic identify Phase sequence, phase failure protection.

2. DC24V Voltage Class for remote control.

3. Convenient and flexible for wiring way.

4. Impenetrable design to improve the sealing of actuator for local button box.

5. Five pieces dry contact signal indicate the working situation of actuators, conveniently monitor for DCS system.

6. Setting monitoring relay, supplying comprehensive fault signal for DCS system.

7. For turn button, can use common padlock locking according to requirements to prevent the false operation.
