Industrial Gate Valve Dimension Details
Typical Applications of DIN PN64 Cast Steel Gate Valve
• High-pressure steam systems: boiler steam, main steam, and power plant high-pressure auxiliary lines.
• Boiler feedwater: high-pressure feedwater lines in power generation and industrial boilers.
• Refinery and petrochemical: high-pressure process lines with elevated temperature service conditions.
• Chemical plants: high-pressure chemical synthesis with CF8M / alloy steel options.
• Power generation: high-pressure cooling water, service water, and auxiliary systems.
• European and international projects: pipelines requiring DIN 3352 / DIN 3202-F5 / DIN 2501 compliance at PN64 pressure rating.
FAQ - DIN PN64 Cast Steel Gate Valve
Q1: What is a DIN PN64 cast steel gate valve?
A: A DIN PN64 cast steel gate valve is a linear motion valve designed for on-off service in 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. PN64 means the valve is rated for 64 bar (6.4 MPa) nominal pressure.
Q2: What is the difference between DIN PN40 and DIN PN64 gate valves?
A: DIN PN64 gate valves have thicker wall sections, heavier flanges, and higher pressure/temperature ratings than PN40. They feature metal seated hardfaced wedge design and are available with RTJ flange facing for enhanced sealing integrity. PN40 is preferred for general high-pressure steam and boiler feedwater, while PN64 is preferred for high-pressure steam, refinery, and petrochemical services.
Q3: What is the size range of DIN PN64 gate valves?
A: This DIN PN64 cast steel gate valve is available in sizes DN50 to DN400 (2″ to 16″), covering a wide range of high-pressure industrial pipeline applications. Other sizes are available on request.
Q4: What materials are available for DIN PN64 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: Why is RTJ facing recommended for PN64 gate valves?
A: RTJ (Ring Type Joint) uses a metal ring gasket in a grooved flange facing, providing superior sealing integrity under high pressure and temperature. For PN64 and above, RF (Raised Face) may not be sufficient in critical service, so RTJ is the recommended choice.
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 PN64 service, hard seal is typically required.
