DIN PN40 vs DIN PN64 Globe Valve: Key Differences
| Parameter | PN40 | PN64 |
|---|---|---|
| Pressure Rating | 40 bar (4.0 MPa) | 64 bar (6.4 MPa) |
| Wall Thickness | Thicker than PN25 | Maximum wall thickness |
| Flange Standard | DIN 2501 PN40 | DIN 2501 PN64 |
| Flange Face | RF, RTJ | RF, RTJ recommended |
| Typical Application | Boiler feedwater, high-pressure steam, chemical process | Ultra-high-pressure steam, refinery, power plant critical service |
Reference: DIN 3356, DIN 2501. PN64 globe valves provide higher pressure containment for high-pressure steam and critical chemical service compared to PN40.

Typical Applications of DIN PN40 - PN64 Globe Valve
• High-pressure steam systems: boiler steam, main steam, and power plant auxiliary steam lines.
• Boiler feedwater: medium-high pressure feedwater lines in power generation and industrial boilers.
• Refinery and petrochemical: process lines with elevated pressure and temperature service conditions.
• Chemical plants: high-pressure chemical synthesis and corrosive media handling.
• Power generation: cooling water, service water, and high-pressure auxiliary systems.
• European and international projects: pipelines requiring DIN 3356 / DIN 3202 / DIN 2501 compliance at PN40 and PN64 pressure ratings.
FAQ - DIN PN40 - PN64 Globe Valve
Q1: What is a DIN PN40 / PN64 globe valve?
A: A DIN PN40 / PN64 globe valve is a linear motion valve designed for throttling and flow regulation in medium-high to high pressure 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. PN40 means the valve is rated for 40 bar (4.0 MPa) nominal pressure, and PN64 for 64 bar (6.4 MPa).
Q2: What is the difference between DIN PN40 and DIN PN64 globe valves?
A: DIN PN64 globe valves have thicker wall sections, heavier flanges, and higher pressure/temperature ratings than PN40. PN64 is suitable for high-pressure steam, refinery, and power plant critical service, while PN40 is preferred for boiler feedwater, medium-high pressure steam, and chemical process 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 PN40 / PN64 globe valves?
A: Common body materials include GS-C25, WCB, WC6, WC9, C5, C12, 1.4308, 1.4408, CF8, CF8M, CF3, and CF3M. 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, RTJ) 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.
