Performance Analysis of 3" 2500LBPerformance Analysis of 3" 2500LB Pneumatic Actuator Ball Valves

In industrial pipeline control systems, the 3" 2500LB PNEUMATIC ACTUATOR BALL VALVES have become the first choice for many industries due to their outstanding performance. This article will introduce their performance characteristics in detail through comparative analysis.

I. Performance Characteristics

(A) Sealing Performance

• Sealing Principle: Soft or hard sealing structures are adopted. The soft sealing is suitable for clean fluids, while the hard sealing is applicable to fluids containing particulate impurities.

• Sealing Grade: It reaches ANSI B16.104 Class VI level, with almost no internal leakage.

(B) Operating Performance

• Advantages of Pneumatic Actuator: It has a fast response and is sensitive in operation, without the need for complex electrical circuits.

• Switching Speed: The opening and closing can be completed within a few seconds to more than ten seconds, which is suitable for emergency shutdown and frequent adjustments.

(C) Pressure Resistance Performance

• Pressure Rating: 2500LB (approximately 17.24MPa), suitable for high-pressure working conditions.

• Pressure Resistance Test: It has passed 1.5 times the water pressure test and 1.1 times the air pressure test to ensure safety and reliability.

(D) Corrosion Resistance Performance

• Material Selection: The valve body is made of corrosion-resistant materials such as 316 stainless steel. Duplex stainless steel or nickel-based alloys can also be selected.

• Surface Treatment: Sandblasting, polishing, and coating (such as epoxy resin, polytetrafluoroethylene) are used to enhance the corrosion resistance.

(E) Service Life

• Wear Resistance: The ball and valve seat are made of high-hardness materials. Ceramic materials can be selected to significantly improve wear resistance.

• Maintenance: It is simple and easy. Regular inspection of the air source and sealing parts can extend the service life.
