Marine J41H Steel Flanged Globe Valve

About product

The Marine J41H steel globe valve is a flanged-end valve designed for a wide range of pressure ratings

  • PN16~PN420 and 150LB-2500LB.
  • operating pressures ranging from 1.6 to 42.0MPa
  • withstand temperatures from -29 to +550℃.

This globe valve is specifically designed for use in industries such as petroleum, chemical, pharmaceutical, chemical fertilizer, and power, catering to various pipeline conditions.

The J41H steel globe valve is capable of handling different types of media, including water, oil, steam, and acid mediums. It is commonly constructed using materials such as cast steel (WCB, LCB, WCC), stainless steel (CF8(M), CF3(M)), and forged steel (A105, F304(L), F316L). These materials are chosen for their durability and compatibility with the specified working conditions.

Product Detail

J41H Flanged Globe Valve Components

The components of the J41H globe valve include the valve structure, clack and valve seat, valve stem, flange compatibility, valve body materials, and sealing mechanism. This flanged globe valve features a well-designed structure, ensuring reliability, efficient sealing, exceptional performance, and an aesthetically pleasing appearance. The valve’s clack and the sealing surface of the valve seat are constructed using wear-resistant, high-temperature-resistant, and corrosion-resistant materials such as iron-based alloy or Stellite cobalt-based alloy, which significantly extends its service life.

The valve stem undergoes a quenching and tempering process, along with surface permeability ammonia treatment, enhancing its corrosion resistance and abrasion resistance properties. This ensures optimal performance and durability.

The Marine J41H steel globe valve is designed to accommodate various piping flange standards and flange sealing surface modes, meeting the diverse requirements of engineers and users. The valve body materials offer a wide range of options, allowing for suitable customization based on specific operational conditions, user preferences, and requirements. The valve is suitable for different pressure, temperature, and medium operating modes.

The valve’s reliable sealing mechanism enables convenient and quick replacement of the sealing material without the need to halt the system’s operation, ensuring uninterrupted functionality and efficiency. This feature adds to the valve’s convenience and ease of maintenance.

Material Selection for J41H Flanged Globe Valve in Marine Applications

Globe valves used in marine applications are constructed using different materials to suit specific requirements.

Cast steel globe valve (WCB, LCB, WCC) is commonly employed in marine industries such as shipbuilding, offshore platforms, and marine pipelines. These materials offer exceptional strength, corrosion resistance, and durability, making them well-suited for demanding marine environments.

Stainless steel globe valve (CF8(M), CF3(M)) is preferred for marine applications where corrosion resistance is critical, such as seawater cooling systems, desalination plants, and marine fuel systems. Stainless steel grades like CF8(M) and CF3(M) are renowned for their ability to withstand corrosion and high temperatures.

Forged steel globe valve (A105, F304(L), F316L) is utilized in marine sectors that require resistance to high pressure and temperature, such as marine oil and gas exploration and production. Materials like A105, F304(L), and F316L are chosen for their strength, toughness, and corrosion resistance.
