Forging Steel Low Temperature Globe Valve

Our Forging Steel Low Temperature Globe Valve is a high-performance industrial valve specifically crafted for systems handling low-temperature media. Adopting precision forging technology, the valve body and key components are made of high-quality forged steel, which enhances mechanical strength, toughness and corrosion resistance compared to cast steel valves – making it ideal for harsh low-temperature working conditions where reliability and safety are paramount. Unlike conventional globe valves, this product is optimized for ultra-low temperature operation, capable of withstanding extreme cold down to -196°C, while maintaining excellent sealing performance and smooth flow control.

Widely used in industries such as LNG storage and transportation, petrochemical, chemical, aerospace, industrial gas and cryogenic engineering, this valve is the preferred choice for controlling the flow of liquefied gases (LNG, liquid oxygen, liquid nitrogen, etc.) and other low-temperature media, ensuring system stability and operational safety.

1.Superior Low-Temperature Adaptability : Specially designed for ultra-low temperature environments, with an operating temperature range of -196°C to -150°C (customizable according to requirements), effectively preventing frost damage, thermal shock and performance degradation caused by extreme cold. The extended bonnet structure keeps the packing area close to ambient temperature, maintaining seal integrity and avoiding seal failure due to low-temperature shrinkage.

2.Precision Forging Craftsmanship : The valve body, bonnet and stem are made of high-quality forged steel (ASTM A105, A350 LF2, A182 F304/F316, etc.), through high-pressure forging process, which eliminates internal defects of the material, improves density and mechanical strength. It can withstand high pressure and frequent temperature changes without deformation or leakage.

3.Zero-Leakage Sealing Performance : Adopts advanced lip seal or metal-to-metal sealing structure, matched with low-temperature resistant sealing materials (PTFE, Kel-F, etc.) that have low shrinkage at cryogenic temperatures. The self-energized seal design with stainless steel or Inconel alloy spring ensures tight sealing even in extreme cold conditions, meeting the strictest leakage standards and avoiding medium loss and safety hazards.

4.Flexible & Labor-Saving Operation : Equipped with outside screw and yoke (OS&Y) configuration, the stem threads are isolated from the medium by packing, avoiding damage from low temperature and corrosive media, and facilitating external maintenance. The valve stem is treated with surface hard chrome plating or nitriding, preventing galling and ensuring smooth on/off control even at extreme temperatures, with small opening and closing torque and easy operation.

5.Enhanced Safety Design : Integrates fire-safe and explosion-proof components to adapt to hazardous low-temperature working environments. The main pressure-containing components are treated with liquid nitrogen to stabilize dimensions and eliminate stress caused by metal microstructure changes, ensuring long-term safe operation. Optional reverse sealing structure further enhances sealing reliability under high-pressure conditions.

6.Low Maintenance & Long Service Life : The robust forged steel structure and corrosion-resistant surface treatment reduce wear and tear, minimizing maintenance frequency and downtime. The valve is designed for continuous long-term performance under low-temperature and low-pressure conditions, with a service life far exceeding that of ordinary valves, helping you reduce overall operating costs.
