Explosion-proof valve actuators play an important role in many industrial fields, especially in flammable and explosive chemical, oil and gas industries. Proper operation of explosion-proof valve actuators not only ensures safety and efficiency in the production process, but also protects workers and equipment from potential hazards. So, let's understand the following explosion-proof valve actuator operation guide.

1 Safety Guidelines

Before performing any operation, the safety operation procedures must be strictly observed. The operator needs to wear appropriate personal protective equipment, such as explosion-proof clothing, safety helmet, safety shoes, goggles, etc. It is necessary to ensure that the explosion-proof valve actuator meets the relevant explosion-proof safety certification standards and the operating environment meets the explosion-proof requirements. Before entering the operation site, gas detection should be carried out to ensure that there is no flammable and explosive gas leakage. All power and signal circuits should be checked to ensure that they have sufficient protection level.

2. Inspection before startup

Before starting the explosion-proof valve actuator, a detailed visual inspection should be carried out to ensure that there is no obvious physical damage, and all wiring should be carefully checked to ensure that it is correct before turning on the power supply. Check whether the power supply voltage is consistent with the voltage marked on the nameplate of the actuator, and confirm that there is no error before starting the operation. Check whether the lubricating grease is sufficient, and supplement and replace it according to the regulations in the product manual.

3. Operation Guide

When operating the explosion-proof valve actuator, strictly follow the manufacturer's operating instructions, switch the actuator to manual operation mode, manually rotate the valve to partially open state, ensure that the valve can move freely and is not blocked, return the actuator to automatic mode, and use the buttons or switches on the control panel to control the opening and closing of the valve. In the process of mobilizing the valve, keep your attention focused, monitor the operation of the actuator, listen to the operation of the device, any abnormal sound should be stopped immediately to check.

4. Maintenance

Regular maintenance of explosion-proof valve actuators is the key to ensure their long-term safe and stable operation. Make maintenance plan and record the details of each maintenance. Regularly replace wear and tear parts, such as seals, gears, etc., and add or replace lubricants on time. Ensure that all components in the electric, pneumatic or hydraulic system are kept clean to prevent the accumulation of dust and dirt. For electrical components in explosion-proof areas, it is especially necessary to check their explosion-proof integrity to avoid potential safety threats. Any problems found should be repaired immediately by following the troubleshooting steps in the instruction manual or contacting the manufacturer.

5. Emergency Treatment

In any emergency situation, the first step is always to ensure personal safety, and then cut off the power of the actuator and put the valve in a safe state. Immediately notify safety and maintenance personnel, and avoid handling complex or dangerous failures by yourself. In case of explosion or fire, immediately start the emergency evacuation procedure and operate according to the factory emergency plan.

How to choose the right electric valve actuator

The electric device of the electric valve is an indispensable equipment for the realization of the valve program control, automatic control and remote control, and its movement process can be controlled by the size of the stroke, torque or axial thrust. Since the working characteristics and utilization of the valve electric device depends on the type of valve, the device work specification and the position of the valve in the pipeline or equipment, the correct selection of the valve electric device is essential to prevent overload phenomenon (working torque is higher than the control torque).
