BS1873 Flanged globe valves

I. BS1873 flanged globe valve J41H-150LB Product introduction
BS1873 Flanged Globe Valve J41H-150LB is a high performance industrial valve designed to meet harsh industrial environments. The products are manufactured in strict compliance with international advanced standards such as BS1873, ensuring excellent quality and reliability. J41H in J41H-150LB indicates that the valve type is manual flange globe valve, while 150LB indicates that its design pressure class is Class 150LB, suitable for a variety of high pressure conditions.

II. BS1873 flanged globe valve J41H-150LB valve body material and sealing performance:
The valve body can be made of 304 stainless steel/316 stainless steel/304L stainless steel/316L stainless steel/321 stainless steel/310S stainless steel/CF8 stainless steel/CF8M stainless steel/CF3 stainless steel/CF3M stainless steel/904L stainless steel/2205 stainless steel/2507 stainless steel and other materials according to customer requirements, meeting high strength, but also has good corrosion resistance, temperature resistance and impact resistance.
The sealing surface can be made of Cr13 series stainless steel or STL alloy or hard sealing material, which ensures the sealing reliability of the valve under high pressure and high temperature. Excellent wear resistance, corrosion resistance and friction resistance, effectively extending the service life of the valve.

III. BS1873 Flanged Globe Valve J41H-150LB Design and Manufacturing Standard:
Product design and manufacturing strictly comply with ASME B16.34, API 6D and other international standards to ensure the interchangeability and versatility of products.
The length of the structure conforms to ASME B16.10 standard, and the flange connection conforms to ASME B16.5 standard, which ensures the stable connection of the valve in the pipeline system.

IV. BS1873 flange stop valve J41H-150LB Scope of application and medium:
J41H-150LB flanged globe valve is widely used in petrochemical, metallurgical, chemical, power station, pharmaceutical and other industries, especially suitable for high pressure, high temperature and corrosive medium pipeline system.
Medium range of application, including water, steam, oil, etc., design temperature up to 180℃, nominal pressure PN to meet a variety of needs.
Five, BS1873 flange stop valve J41H-150LB structural characteristics
1. Simple structure and convenient maintenance:
Flanged globe valve structure design is simple, fewer parts, easy to install and maintain. During maintenance, seals can be quickly removed and replaced, reducing downtime.
2, superior sealing performance:
Conical sealing structure is adopted, friction between sealing surfaces is small, and sealing effect is reliable. Even under high pressure, high temperature or corrosive medium conditions, it can maintain good sealing performance.
3, open and close quickly, easy to operate:
The opening and closing action of the valve is rapid, the operating torque is small, and the manual operation is light. For large-diameter, high-pressure valves, gear transmission, electric or pneumatic drive can also be used to achieve remote automation control.
4. Low fluid resistance:
The straight-through flow channel design makes the fluid resistance small and the pressure loss small, which is suitable for the pipeline system with high flow requirements.
5. Strong adaptability:
Flanged globe valves can be customized according to actual working conditions, such as stem material, sealing surface material, flange size, etc., to meet the requirements of different media and working environment.
6. High safety:
When the valve is closed, the medium is completely cut off, ensuring the safety of the pipeline system. At the same time, the sealing performance of the valve also avoids the harm of medium leakage to the environment and equipment.
