FAQ - DIN PN100 - PN160 High Pressure Globe Valve
Q1: What is a DIN PN100 / PN160 globe valve?
A: A DIN PN100 / PN160 globe valve is a linear motion valve designed for throttling and flow regulation in ultra-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. PN100 means the valve is rated for 100 bar (10.0 MPa) nominal pressure, and PN160 for 160 bar (16.0 MPa).
Q2: What is the difference between DIN PN100 and DIN PN160 globe valves?
A: DIN PN160 globe valves have thicker wall sections, heavier flanges, and higher pressure/temperature ratings than PN100. PN160 is typically supplied with pressure seal bonnet (PSB) and RTJ facing for ultra-high-pressure service. PN100 is preferred for high-pressure steam, refinery, and chemical process applications up to 10.0 MPa.
Q3: What is a pressure seal bonnet (PSB) and why is it used for high pressure?
A: Pressure seal bonnet uses internal line pressure to tighten the seal between the bonnet and body. As pressure increases, the sealing force increases, making it more reliable than bolted bonnet at very high pressure and temperature. PSB is recommended for PN100 and above in critical service, particularly for PN160 where the pressure is extremely high.
Q4: What materials are available for DIN PN100 / PN160 globe valves?
A: Common body materials include GS-C25, WCB, 1.4308, 1.4408, CF8, CF8M, CF3, CF3M, WC6, WC9, C5, and C12. 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 and gear operated. 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.
