The cast steel gate valve type VA430 is a flanged gate valve in 1.0619 with a metal-sealing 13Cr seat. It suits process media at temperatures up to 400 \u00b0C. Body and bonnet consist of cast steel 1.0619. In addition, the wedge uses 1.0619 with 13Cr hard-facing. The gland packing is graphite, conforming to TA-Luft requirements.<\/p>\n\n\n\n
This wedge gate valve cast steel covers nominal sizes DN40 to DN300. It is available in pressure ratings PN10 and PN16. Flange drilling conforms to EN 1092-1<\/a> Form B1. Furthermore, the face-to-face length follows DIN EN 558-1 Series 14 (F4). The bolted bonnet construction with outside screw and yoke (OS&Y) stem provides reliable actuation by handwheel. The gate valve TA-Luft 1.0619 holds approvals to AD2000, NACE MR0175 and PED 2014\/68\/EU. Finally, FERGO supplies the cast steel gate valve DN300 ex stock.<\/p>\n\n\n\n The cast steel gate valve is available in nominal sizes DN40 to DN300. Pressure ratings cover PN10 and PN16 at a maximum operating pressure of 16 bar. In addition, the maximum operating temperature is 400 \u00b0C. Flange drilling conforms to EN 1092-1 Form B1. Moreover, the face-to-face length to DIN EN 558-1 Series 14 (F4) is the standardised short length. The design to EN 1984 with full bore minimises pressure loss across the valve. The rising stem (OS&Y) with bolted bonnet provides visual position indication. As a result, it allows straightforward access to internals for maintenance. The gate valve PN16 cast steel comes with handwheel actuation.<\/p>\n\n\n\n The body consists of 1.0619. This heat-resistant cast steel suits elevated-temperature service and aggressive media. The wedge in 1.0619 with 13Cr hard-facing and the 13Cr seat ring form a metal-to-metal seal. This design ensures reliable shut-off up to 400 \u00b0C. The stem in X20Cr13 provides corrosion resistance. Moreover, the body gasket in SS304 with graphite is TA-Luft compliant. Bolting to ASTM A194 2H \/ ASTM A193 B7 is rated for high-temperature duty. Approvals include AD2000 for pressure equipment, NACE MR0175 for sour-gas service, PED 2014\/68\/EU and TA-Luft for fugitive-emission sealing.<\/p>\n\n\n\n The cast steel gate valve protects pipelines in the chemical and petrochemical industry, power plants and oil and gas production. The metal-to-metal seal with 13Cr seat handles water, wastewater, steam, gases and aggressive liquids. It is rated for temperatures up to 400 \u00b0C. NACE approval enables deployment in environments containing hydrogen sulphide. In addition, the TA-Luft-compliant packing ensures tightness against fugitive emissions.

Applications and Ordering of the High-Temperature Gate Valve<\/h3>\n\n\n\n
Steel wedge gate valve: metal-seated<\/h2>\nWedge gate valves are used to control the flow of liquids by raising or lowering a solid gate or wedge to open or close the passage. They are typically used in systems where full, unobstructed flow or complete shut-off is required. Thanks to the metal Seat, they can also be used at higher temperatures.\n\nThe VA430 wedge gate valve is a high-quality industrial valve distinguished by its robust design and high reliability. It features a bolted Lid and an outside screw and yoke (OS&Y), ensuring easy maintenance and a long service life. The flanged gate valve is equipped with a flange connection PN10\/PN16 to EN 1092-1, form B1, and has a Face-to-face to EN 558-1, series 14.\n\nManufactured from high-quality materials such as 1.0619 (steel) for the Case Lid and X20Cr13 for the stem, the VA430 wedge gate valve is designed for demanding operating conditions. The Seat is made of 13Cr, ensuring high wear resistance. The graphite packing meets TA Luft requirements for particularly tight sealing, even at higher temperatures. The VA430 is designed for a maximum operating pressure of 16 bar and a maximum operating temperature of 400\u00b0C. It is manually operated via a handwheel and complies with key standards such as AD2000, NACE, PED2014\/68\/EU and TA Luft.\n\nThis gate valve is ideal for use in the chemical and petrochemical industry, power plants, and oil and gas production. It is particularly suitable for media such as water, wastewater, steam, gases and aggressive liquids that place high demands on the material and tightness.\n\nWedge gate valve VA430 (item no.: 201-4063-xx) PN10\/16-DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300<\/strong>\n
