Products Details

Forged steel welded Y-type globe valve is a valve used in industrial piping systems, mainly used to cut off or connect the flow of media. Here's the Chinese version, based on search results:

Structural features: Y-shaped forged steel globe valves usually have a Y-shaped structure, which helps to reduce the resistance of fluid flow. Valves may be of full or reduced diameter design, the disc may be plain or needle shaped, the bonnet may be bolted, welded or pressure sealed, and the end connections may be flanged, butt welded, socket welded or threaded.

Technical specifications: Sizes typically range from DN15 to DN50 (1/2 inch to 2 inch), pressure grades from 150LB to 2500LB, materials including A105, F5, F6, F11, F22, F304, F316, etc., are designed and manufactured in accordance with API 602, BS 5352, ASME B16.34, etc.

Materials and applications: Forged steel welded Y-type globe valves are available in a variety of materials, suitable for different media and temperature ranges. For example, the material of the valve body and valve cover can be carbon steel, alloy steel or stainless steel, and the sealing surface material can be selected according to the medium characteristics. Applicable media include water, steam, oil, nitric acid, acetic acid, etc., applicable temperature range from -29℃ to 550℃.

Connection method: There are many ways to connect the end of the valve, including flange connection, butt welding connection, socket welding connection and threaded connection, in line with ANSI B16.5, DIN2543 and other standards.

Design form: Y-type forged steel globe valve has three valve cover design forms, including bolted valve cover, welded valve cover and self-sealing valve cover to meet different application requirements.

Inspection and testing: Valve inspection and testing in accordance with API 598 and other standards to ensure product quality and performance.

Packing and delivery: Usually packed in wooden cases to ensure safety during transportation.

Manufacturers: Many professional valve manufacturers, such as Zhejiang Xiongtai Valve Manufacturing Co., LTD., Shanghai Shigao Valve Co., LTD., provide a variety of specifications and materials of forged steel welded Y-type globe valve, and have ISO9001 quality certification, to ensure product quality.

In summary, forged steel welded Y-type globe valve has been widely used in petrochemical, electric power, metallurgy, medicine and other industries because of its compact structure, good sealing performance and wide application range.
