What is a PN16/40 3PC Flanged Ball Valve?
A PN16/40 3PC Flanged Ball Valve is a reliable quarter-turn valve designed for industrial pipeline systems. It uses a spherical ball with a central bore to control fluid flow. When the valve handle rotates 90 degrees, the flow path opens or closes instantly, ensuring efficient flow control. The 3PC (three-piece) structure allows for easy disassembly and maintenance, enhancing usability in industrial scenarios, while the dual pressure rating (PN16/40) adapts to diverse medium and high-pressure working conditions.
The flanged design allows the valve to be directly connected to pipeline flanges, ensuring stable installation and tight sealing, which is more suitable for medium-pressure industrial scenarios compared with wafer type valves.
This type of valve is widely used in oil & gas, petrochemical, water treatment, chemical processing, and general industrial pipelines (especially in European markets) due to its reliable sealing performance, durable materials, and compliance with EU industrial standards.
Key Advantages of PN16/40 3PC Flanged Ball Valves
Stable Flanged Connection
The flanged body structure is designed to be directly connected to pipeline flanges, ensuring stable installation, strong pressure-bearing capacity, and tight sealing—ideal for European industrial pipelines requiring reliable connection and dual pressure operation (PN16/40).
Blow-Out Proof Stem Design
The valve stem is internally mounted to prevent accidental ejection during high-pressure operation, improving overall operational safety, meeting EU industrial safety requirements, and ensuring safe use in European factories and hazardous environments.
Anti-Static Safety Device
An anti-static device ensures electrical continuity between the ball, stem, and valve body. This feature prevents electrostatic buildup, which is critical for hazardous industrial environments such as oil and gas facilities in Europe, complying with EU safety norms.
Optional Fire Safe Design
Equipped with optional fire safe design (API 607 4th Edition), specially designed for fire-risk industrial scenarios (such as petrochemical, oil & gas), providing extra safety guarantee for pipeline operation in European hazardous workplaces.
Excellent Sealing Performance
Precision-machined stainless steel balls combined with high-performance sealing materials provide tight shut-off and long service life, adapting to pressure working conditions (PN16/40) in European industrial pipelines, and complying with DIN3202 (F4) face-to-face dimension standards.
Corrosion-Resistant Materials
Multiple stainless steel and carbon steel materials are available to ensure compatibility with corrosive or aggressive fluids, suitable for diverse European industrial scenarios (petrochemical, water treatment, marine) and complying with EU environmental standards.

FAQ – PN16/40 3PC Flanged Ball Valve
What does PN16/40 mean in a flanged ball valve?
PN16/40 indicates the dual pressure rating of the valve, meaning it is designed to operate at a maximum pressure of 16 bar (PN16, equivalent to 150Ibs) and 40 bar (PN40, equivalent to 300Ibs) under standard conditions, adapting to both medium and high-pressure European industrial pipelines.
What is the advantage of the 3PC (three-piece) structure?
The 3PC (three-piece) structure allows for easy disassembly and maintenance without removing the entire valve from the pipeline. This reduces downtime in industrial operations, lowers maintenance costs, and extends the valve’s service life—ideal for European factories pursuing efficient maintenance.
What is the difference between a flanged ball valve and a wafer ball valve?
A flanged ball valve has its own flanges for direct connection to pipeline flanges, ensuring more stable installation and stronger pressure-bearing capacity (suitable for PN16/40 dual pressure scenarios). A wafer ball valve is installed between two pipeline flanges without its own flanges, focusing on space-saving. Flanged ball valves are more suitable for demanding industrial pipelines requiring reliable connection.
Is the fire safe design mandatory for this valve?
No, the fire safe design (API 607 4th Edition) is optional. It is recommended for fire-risk industrial scenarios such as petrochemical and oil & gas facilities in Europe, providing extra safety guarantee in case of fire.
What materials should I choose for corrosive media in European chemical plants?
For corrosive media in European chemical plants, we recommend CF8 (304 stainless steel) for mild corrosion, CF8M (316 stainless steel) for moderate corrosion, and CF3M (316L stainless steel) for harsh corrosive environments (such as marine, pharmaceutical), all complying with EU environmental standards.
Which actuator is suitable for European automatic production lines?
Pneumatic actuators are suitable for general automatic production lines, with fast response and high efficiency. Electric actuators are recommended for scenarios requiring remote control and integration with digital control systems (such as SCADA), both compatible with EU standard control systems and the valve’s ISO5211 mounting pad.
Does the valve comply with European pipeline standards?
Yes, the valve is designed and manufactured in accordance with DIN3357/1,2 and EN12516-1 standards, with face-to-face dimension DIN3202 (F4) and flange standard DIN2501 PN10-PN40, fully complying with European industrial standards and ensuring interchangeability with European pipeline systems.
