Frecy explosion-proof electric actuator

Frecy explosion-proof electric actuator

1. Product Overview

The "FHQ" series explosion-proof electric actuator is used to control valves and other similar products that rotate from 0 ° to 270 °, such as butterfly valves, ball valves

Air doors, baffle valves, plug valves, louver valves, etc. can be widely used in petroleum, chemical, water treatment, shipbuilding, papermaking, power plants, etc

In various industries such as heating, building automation, and light industry. It is driven by a 380V/220V/110V AC power supply and operates at 4-20mA

The current signal or 0-10V DC voltage signal is used as the control signal to move the valve to the desired position and achieve its automatic control,

The large output torque reaches 4000 N • M. (This product has obtained CE and explosion-proof certification, and its quality is guaranteed.)

2. Performance characteristics

2.1 Shell

The shell is made of hard aluminum alloy, which has undergone anodizing treatment and polyester powder coating, with strong corrosion resistance and a protection level of IP67 and NEMA4

And 6, with IP68 and explosion-proof options available.

2.2 Motor

Fully enclosed squirrel cage motor, small size, high torque, low inertia force, insulation level of F, built-in overheat protection switch,

Can prevent motor damage caused by overheating.

2.3 Manual Structure

The design of the handwheel ensures safety, reliability, labor-saving, and small size. When there is no power, manual operation can be performed by pulling the clutch handle. through

When electric, the clutch automatically resets. (Note: When the motor is not powered, the electric actuator will remainManual mode)

2.4 Indicator

The indicator is installed on the central axis to observe the position of the valve. The mirror adopts a convex lens design, which prevents water accumulation and makes observation more convenient.

2.5 Drying machine

Used to control temperature, prevent condensation of moisture inside the actuator due to temperature and weather changes, and keep the internal electrical components dry

Dry.

2.6 Limit switch

Mechanical and electronic dual limit. The mechanical limit screw is adjustable, safe and reliable; The electronic limit switch is controlled by a cam mechanism, which is simple

The single adjustment mechanism can accurately and conveniently set the position without the need for battery support. (Micro switch contacts are all silver contacts)

2.7 Torque switch

Overload protection can be provided (excluding FHQ-005/008/010), which automatically disconnects the motor power supply in case of valve jamming or foreign objects

Effectively protect valves and electric actuators from damage. (It has been set before leaving the factory, please do not change the settings arbitrarily)
