Electric Flow Control Valve

Our electric flow control valve is an improved product based on our factory's optimized traditional structure, offering reliable quality. It is widely used in pipelines for flow control of dusty materials in industries such as metallurgy, mining, and building materials. The main valve body of the flow control valve is identical to that of the shut-off valve; the only difference lies in the driving device. The drive unit of the flow control valve is an adjustable electric actuator, and the flow control valve is often used in series with a pneumatic shut-off valve.

Installation Requirements

1. During construction, the foundation shall be installed in accordance with the installation base drawing to meet the load-bearing requirements.

2. Mechanical installation shall comply with applicable national standards and specifications.

3. Electrical control wiring shall conform to the specified requirements.

4. According to the packing list, check and verify that the actual delivered items are consistent with the list.

5. Become familiar with the general assembly drawing and the operating performance and requirements of the electric flow control valve.

6. Install the mounting brackets and support frames in accordance with the process flow diagram and the equipment general arrangement drawing.

Trial Operation

1. Connect the power supply and check whether the voltage meets the requirements and the power indicator is functioning properly.

2. Start the electric flow control valve and check:

   - Whether the direction of movement is correct;

   - Sealing performance;

   - Inflation/aeration system (if applicable);

   - Operational stability and whether the motor shows signs of overheating due to overload.

3. Start the upstream shut-off valve/flow control valve and verify stable operation.

4. Once all mechanical components are running normally, proceed with a full trial operation.

Maintenance & Servicing

1. Periodically check all bolted connections for looseness; if any are found, re-tighten them.

2. Regularly lubricate the transmission and moving parts with appropriate lubricants based on actual operating conditions.

3. Periodically inspect electrical components for reliable operation; replace any damaged contacts or components immediately.

4. Regularly clean dust accumulation from all parts to ensure safe and reliable operation.

5. Motors, gear reducers, electric actuators, and other mechanical equipment shall be inspected and maintained strictly in accordance with their respective instruction manuals.
