The operating specifications for flange globe valves mainly include the following aspects:

1、 Preparation before operation

Personnel qualifications: Ensure that operators have relevant experience and skills in operating flange globe valves.

Familiar with the equipment: Refer to the user manual to understand the performance characteristics and operating requirements of the flange globe valve.

Confirm parameters: Determine the medium and working pressure of the system where the valve is located, ensuring that the rated parameters of the valve are not exceeded during operation.

2、 Operation steps

Open the valve:

Rotate the valve handwheel counterclockwise until the valve core is fully opened.

During the operation, attention should be paid to observing the opening of the valve to ensure that it is fully open.

Control the flow rate of the medium:

Adjust the valve opening appropriately as needed to control the flow rate and pressure of the medium.

During the adjustment process, smooth operation should be carried out to avoid sudden changes that may cause system instability.

Close the valve:

Rotate the valve handwheel clockwise until the valve core is completely closed, achieving the medium cutoff effect.

After closing the valve, it should be confirmed whether the valve is completely closed and observed for any leakage around the valve.

Check valve sealing:

After closing the valve, confirm the sealing condition of the valve by observing whether there is any leakage around the valve.

If a leak is found, it should be dealt with promptly to ensure the sealing performance of the valve.

3、 Safety precautions

Personal protection: Operators should wear appropriate protective equipment such as gloves, glasses, etc. to prevent accidental injuries.

Follow the regulations: During the operation process, relevant regulations and operation guidelines should be followed, and overloading operation is strictly prohibited.

Abnormal situation handling: In the process of operation, if any abnormal situation is found (such as water leakage, leak, etc.), it should be immediately stopped from use and inspected and repaired.

Prohibition of unauthorized disassembly: It is strictly prohibited to disassemble and replace valve components without authorization to avoid affecting the normal operation of the equipment.

4、 Maintenance and upkeep

Regular inspection: Regularly inspect the flange globe valve, including appearance, sealing performance, operational flexibility, and other aspects. If any abnormalities or damages are found, they should be dealt with or replaced in a timely manner.

Cleaning and maintenance: Regularly clean the valve to remove surface dirt and impurities. Be careful to avoid using corrosive cleaning agents during the cleaning process.

Lubrication of operating components: Regularly lubricate the operating components of the valve to reduce friction and wear. Use appropriate lubricating oil or grease and lubricate according to the operating requirements.

In summary, the operating specifications for flange globe valves cover multiple aspects such as preparation before operation, operating steps, safety precautions, and maintenance. Following these specifications can ensure the safe and effective use of flange globe valves, and extend their service life.
