DIN PN16 vs DIN PN25 Globe Valve: Key Differences
| Parameter | PN16 | PN25 |
|---|---|---|
| Pressure Rating | 16 bar (1.6 MPa) | 25 bar (2.5 MPa) |
| Wall Thickness | Standard | Thicker, reinforced |
| Flange Standard | DIN 2501 PN16 | DIN 2501 PN25 |
| Face to Face | DIN 3202 Series 1 | DIN 3202 Series 1 |
| Typical Application | Water treatment, HVAC, general industrial service | High-pressure steam, boiler feedwater, chemical process |
Reference: DIN 3356, DIN 2501. PN25 globe valves provide higher pressure containment for medium-high pressure service compared to PN16.

Typical Applications of DIN PN16 - PN25 Globe Valve
• Water treatment and distribution: municipal water supply, distribution networks, and wastewater treatment plants.
• HVAC and district heating: heating, ventilation, air conditioning, and district heating pipelines requiring flow regulation.
• Chemical and petrochemical: process lines with corrosive media requiring precise throttling and frequent operation.
• Power generation: boiler feedwater, auxiliary steam, and cooling water systems at PN16 / PN25 pressure ratings.
• General industrial pipelines: non-corrosive and mildly corrosive media requiring reliable flow regulation.
• European and international projects: pipelines requiring DIN 3356 / DIN 3202 / DIN 2501 compliance.
FAQ - DIN PN16 - PN25 Globe Valve
Q1: What is a DIN PN16 / PN25 globe valve?
A: A DIN PN16 / PN25 globe valve is a linear motion valve designed for throttling and flow regulation in European standard pipelines. It is manufactured to DIN 3356 with face-to-face dimensions per DIN 3202, flange ends per DIN 2501, and inspection and test per DIN 3230. PN16 means the valve is rated for 16 bar (1.6 MPa) nominal pressure, and PN25 for 25 bar (2.5 MPa).
Q2: What is the difference between DIN PN16 and DIN PN25 globe valves?
A: DIN PN25 globe valves have thicker wall sections, heavier flanges, and higher pressure/temperature ratings than PN16. PN25 is suitable for high-pressure steam, boiler feedwater, and chemical process service, while PN16 is preferred for water treatment, HVAC, and general industrial applications.
Q3: What is the difference between a globe valve and a gate valve?
A: A globe valve uses a plug that moves along the flow axis, providing better throttling and flow regulation — ideal for modulating service. A gate valve uses a wedge that moves perpendicular to the flow, providing full bore flow with minimal pressure drop — ideal for on-off isolation only. Globe valves should be used for throttling, while gate valves should only be used fully open or fully closed.
Q4: What materials are available for DIN PN16 / PN25 globe valves?
A: Common body materials include GS-C25, 1.4308, 1.4408, WCB, LCB, CF8, CF8M, CF3, CF3M, WC6, WC9, C5, C12, 4A, and 5A. Various trim materials such as 13Cr, STL, SS304, SS316, F6a, F51, and F53 are available to suit different service conditions.
Q5: What end connections and actuation options are available?
A: End connections include flanged (RF) per DIN 2501 and butt weld (BW). Actuation options include manual handwheel, gear operated, and electric actuator. Other options are available on request.
Q6: What is DIN 3356 standard?
A: DIN 3356 is a German industrial standard for "Globe valves for general requirements." It specifies requirements for design, materials, face-to-face dimensions, flange dimensions, and testing of industrial globe valves. It is widely used in European and international projects for flow regulation and throttling applications.
