Products Details

American standard forged steel welded gate valve is a high pressure valve, suitable for a variety of media and working conditions. Here are some of its main features and parameters:

American standard forged steel welded gate valve is suitable for pressure Class150 to 600Lb, operating temperature range from -29℃ to 425℃ (carbon steel) or -29℃ to 500℃ (stainless steel), small diameter pipe used to cut off or connect the medium in the pipeline.

Structural features:

It is suitable for medium and high temperature and high pressure valves with nominal pressure Class150 to 600 and nominal diameter NPS1/2" to 2".
The valve stem and the valve stem nut are driven by trapezoidal thread, and the valve stem head is designed with a conical upper sealing surface to ensure no external leakage when the valve is fully opened.
The valve body, valve cover and other bearing parts are forged as a whole, and the flange can be welded.
The valve seat is connected to the valve body in a variety of ways, including threaded connection, welding or surfacing alloy layer, surfacing layer thickness of not less than 2mm.
Forged steel valves higher than 15.0Mpa adopt pressure self-tightening sealing structure to ensure pressure strength.
Material of main parts: including valve body, valve seat, gate, valve stem, gasket, valve cover, bolt, etc. The material can be carbon steel (CS), alloy steel (AS) or stainless steel (SS) according to the different environment and medium, and the specific material standard refers to ASTM standard.

Connection sizes: Detailed ANSI 150Lb, 300Lb, 600Lb, and 800Lb connection sizes are provided, including NPS dimensions, L, L1, H, D0, Wt, and Wt1 parameters.

Design and manufacturing standards: Design and manufacturing in accordance with ANSI B16.34, API 600, API 602 and other standards to ensure product quality and performance.

Inspection and test: Inspection and test according to API 598 standard to ensure the reliability and safety of the valve.

Applicable media: water, nitrogen and hydrogen gas mixture, urea and methylamine liquid, etc., according to the different valve materials, can be applied to a variety of media.

Temperature range: Depending on the material, forged steel gate valves are suitable for different temperature ranges, such as carbon steel for -29℃ to 425℃, stainless steel for -29℃ to 550℃.

Other features: forged steel gate valve structure is simple, small size, light weight, easy operation, easy maintenance, wide range of application, suitable for petroleum, chemical industry, urban water supply and drainage and other conditions.

Product model: For example, Z41H, Z41Y, etc. The specific model may vary according to different manufacturers.
