Common Problems And Solutions Of Two-piece Flange Ball Valves

flanged ball valve, a crucial component of fluid control systems, are widely used in industries such as petroleum, chemical, and power generation. Due to their simple structure and ease of operation, they are the valve of choice for many industries operating under high-pressure and high-temperature conditions. However, over time, 2 flanged ball valve often face technical issues that, if not promptly addressed, can affect system operation and even cause equipment damage.

This article briefly discusses typical two-piece flanged ball valve issues. It also provides insights into two-piece flanged ball valve repair techniques.

Valve body or seat leakage

Causes

• Aging sealing material
• Worn valve seat surface
• Damaged valve body surface
• Poor sealing due to improper installation
• Adverse operating conditions

Solutions

• Regularly check the condition of the sealing material
• Replace aged or damaged sealing material
• Ensure smooth surfaces of the valve seat and body
• Properly install the valve and operate it according to standards
• Select high-temperature and corrosion-resistant materials

Valve stuck or partially open

Causes

• Impurities on the ball and seat surfaces
• Excessive friction due to insufficient lubrication
• Impurities deposited inside the valve
• Imprecise fit between the valve body and ball
• Excessive external forces interfering with valve operation

Solutions

• Regularly clean the valve interior
• Lubricate the ball and seat
• Use appropriate lubricants
• Regularly check the fit between the ball and seat
• Reduce unnecessary external interference

Sealing Valve Vibration

Causes

• Long-term high-temperature and high-pressure operation
• Fluid erosion causes seal wear
• Poor sealing material quality
• Frequent opening and closing increases wear
• Impurities inside the valve rubbing against the seal

Solutions

• Regularly check seal wear
• Replace aged or damaged seals promptly
• Select high-quality sealing materials
• Reduce the frequency of opening and closing
• Keep the valve interior clean

Valve vibration

Causes

• Excessive fluid velocity
• Improper valve design
• Improper valve installation
• Fluid fluctuations during operation
• Insecure connection between pipe and valve

Solutions

• Optimize valve design to avoid excessive vibration
• Ensure secure connection between valve and pipe
• Reduce fluid fluctuations and shock
• Select vibration-damaging materials or devices
• Adjust fluid flow rate
