Standard BS1873 globe valve

BS1873 Stop Valve J41Y-600LB
BS1873 Globe Valve J 41Y-600LB is a high performance fluid control device, especially suitable for industrial applications requiring high pressure, high temperature or special media treatment. Model J 41Y-600LB conforms to international general valve manufacturing standards, such as ANSI, ASME, etc., and also meets the requirements of similar standards such as BS1873 for valve performance and quality.

Standard BS1873 Globe Valve J41Y-600LB Material Selection
Body material: usually choose forged steel, chromium molybdenum steel or stainless steel and other high strength, corrosion resistant materials, such as WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), etc., these materials can resist the corrosion of various corrosive media, to ensure that the valve in harsh conditions of long-term stable operation.
Sealing surface material: The choice of sealing surface material is very important for the sealing performance of the valve, J 41Y-600LB valve sealing surface is often made of cemented carbide or stainless steel surfacing, such as stellite cobalt based cemented carbide, to improve wear resistance, high temperature resistance, corrosion resistance and scratch resistance.

BS1873 Stop Valve J41Y-600LB Main Characteristics
High Pressure Resistance: 600LB in J41Y-600LB refers to the pressure rating of the valve, that is, the valve can withstand up to 600 pounds (about 41.4MPa) of operating pressure, suitable for high pressure piping system.
Excellent material: the valve body and key parts are often made of forged steel, stainless steel and other high-quality materials, such as 304, 316 stainless steel, etc., with good corrosion resistance and mechanical strength, to ensure long-term stable operation of the valve under harsh conditions.
Reliable sealing: pressure self-tightening sealing structure, when the medium pressure increases, the sealing performance is enhanced to ensure reliable sealing of the valve under high pressure environment. The use of precision sealing structure, such as metal hard seal or soft sealing surface, to ensure that the valve in the closed state without leakage, to meet strict sealing requirements.
Stem design: stem through quenching and surface nitriding treatment, not only to improve the corrosion resistance and abrasion resistance, but also to ensure the smooth operation of the stem in the process of opening and closing.
Flexible operation: Provide a variety of drive modes, including manual, pneumatic, electric, etc., to meet different operational needs. Manual operation is simple, pneumatic and electric operation can realize remote control and automatic control.
Widely used: Widely used in petroleum, chemical, natural gas, pharmaceutical, food and other industries in the pipeline system, used to control the flow of fluid on and off and adjust the flow.
Compliance with standards: Although direct reference to BS1873 standard information is limited, but J 41Y-600LB globe valve usually comply with or refer to international general valve manufacturing standards, such as ANSI, ASME, etc., to ensure that the quality and performance of products reach the international advanced level.
