Stainless Steel 3PC DIN PN16 Flanged Ball Valve

JOEPAI Stainless Steel 3PC DIN PN16 Flanged Ball Valve delivers stable performance under unified calibrated working temperature range of -29℃ to 180℃ with reinforced PTFE sealing ring; when equipped with PPL para polystyrene sealing ring, the ball valve extends the operating temperature upper limit to 300℃. All technical parameters of JOEPAI Stainless Steel 3PC DIN PN16 Flanged Ball Valve are tested in accordance with API 598 inspection standard to eliminate inconsistent temperature description errors on the page. The 3PC DIN Flanged Ball Valve adopts DIN2633 standard PN16/PN40 flange connection, with face-to-face dimension complying with DIN3202-F1 specification. The nominal diameter of JOEPAI Stainless Steel 3PC DIN PN16 Flanged Ball Valve covers DN15 to DN150, covering most common industrial pipeline specifications. Multiple body material options are supplied for JOEPAI 3PC Flanged Ball Valve, including stainless steel 304/1.4308 and stainless steel 316/1.4408, to adapt to neutral, weakly acidic and corrosive fluid environments.

Product features：

Three-piece Split Structure:The biggest competitive highlight of JOEPAI Stainless Steel 3PC DIN PN16 Flanged Ball Valve is its independent 3PC split valve body design. Integrated ball valves require complete pipeline shutdown and pipeline disassembly for internal cleaning, while 3PC Ball Valve only needs to loosen the connecting bolts to take out the middle valve body without removing the whole valve from the pipeline. This 3PC structural feature greatly shortens maintenance downtime and reduces pipeline reconstruction costs for industrial users.

Full Port Through-flow Design:JOEPAI Stainless Steel 3PC DIN PN16 Flanged Ball Valve is equipped with full port ball core as standard configuration. The inner bore diameter of full port ball core is consistent with the pipeline inner diameter, which avoids flow resistance and medium pressure loss caused by reduced flow channel. For circulation pipelines with high flow rate requirements,3PC Ball Valve full port design effectively improves transmission efficiency of water, steam, oil and other media.

Applicable Media & Working Scenarios:

JOEPAI 3PC DIN Flanged Ball Valve can cut off or connect fluid media inside industrial pipelines. With interchangeable sealing rings and multiple valve body materials, this Ball Valve is compatible with water, compressed air, industrial steam, fuel oil, nitric acid, acetic acid and other weakly corrosive liquids. It is widely applied in chemical processing, food beverage production, water supply and drainage, heating pipeline, pharmaceutical manufacturing and environmental protection wastewater treatment industries. Whether it is low-temperature normal-pressure water pipelines or high-temperature steam transmission pipelines, JOEPAI Stainless Steel 3PC DIN PN16 Flanged Ball Valve maintains stable sealing and long service life.

FAQ

1.What does "3PC" mean and why is it important?

"3PC" stands for three-piece construction, where the middle body and two end flanges are bolted together. This design allows easy online maintenance and cleaning without removing the entire valve from the pipeline, which significantly reduces downtime for systems that require regular servicing.

2.What are the main applications and suitable media for this valve?

This valve is used to cut off or connect media flow in pipelines and is suitable for water, steam, oil, nitric acid, acetic acid, and other corrosive fluids. It is widely applied in chemical processing, petrochemical, power generation, and water treatment industries, with material selection tailored to the specific medium.

3.What materials are available for this valve?

Body options include carbon steel (WCB), stainless steel 304, and stainless steel 316. Internal components such as the ball, stem, and bolts are available in matching stainless steel grades, while the seat is made of PTFE for excellent sealing performance.

4.What drive options and safety features does this valve offer?

It supports manual lever, electric, and pneumatic operation. Safety features include a blowout‑proof stem with reverse sealing, a 90° positioning mechanism, an optional locking device to prevent misoperation, and an ISO standard bracket for easy actuator mounting.

5.What sizes are available, and can the valve be customized?

We offer sizes from DN15 to DN150. Customization is available for special materials, pressure ratings, connection types (including butt‑weld and socket‑weld), and packaging. Please contact our sales team with your specific requirements.
