FAQ - DIN PN100 Cast Steel Gate Valve
Q1: What is a DIN PN100 cast steel gate valve?
A: A DIN PN100 cast steel gate valve is a linear motion valve designed for on-off service in ultra-high pressure pipelines. It is manufactured to DIN 3352 with face-to-face dimensions per DIN 3202-F5, flange ends per DIN 2501, and inspection & test per DIN 3230. PN100 means the valve is rated for 100 bar (10.0 MPa) nominal pressure.
Q2: What is the difference between DIN PN64 and DIN PN100 gate valves?
A: DIN PN100 gate valves have thicker wall sections, heavier flanges, and higher pressure/temperature ratings than PN64. They are available with pressure seal bonnet (PSB) construction for extreme pressure service and metal seated hardfaced wedge design. PN64 is preferred for high-pressure steam and refinery processes, while PN100 is preferred for ultra-high-pressure steam, hydrocracking, and turbine bypass services.
Q3: What is the size range of DIN PN100 gate valves?
A: This DIN PN100 cast steel gate valve is available in sizes DN50 to DN400 (2″ to 16″), covering a wide range of ultra-high-pressure industrial pipeline applications. Other sizes are available on request.
Q4: What materials are available for DIN PN100 gate valves?
A: Common body materials include WCB, GS-C25, LCB, CF8, 1.4308, CF8M, 1.4408, CF3, CF3M, WC6, WC9, C5, and C12. Various trim materials such as 13Cr, STL, SS304, SS316, and F6a are available to suit different service conditions.
Q5: What is a pressure seal bonnet (PSB) and why is it used for PN100?
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 the standard choice for PN100 and above in critical service.
Q6: What is the difference between hard seal and soft seal gate valves?
A: Hard seal (metal seated) gate valves use metal-to-metal contact between the wedge and seat, suitable for high temperature and high pressure service, and resistant to wear and erosion. Soft seal (elastomer seated) gate valves use rubber or PTFE seats, providing better sealing performance at lower temperatures but limited by the temperature rating of the soft material. For PN100 service, hard seal with hardfaced sealing surfaces is required.
