Bellows Globe Valve

Bellows Globe Valve
Design to Improve
The Sealing Performance of Stop Valve
The working principle of the bellows seal globe valve is to replace the original stem seal packing with a metal bellows with one end welded on the valve stem and one end sealed between the valve cover and the valve body. The switching and adjustment of the globe valve will compress and Stretching the metal bellows completely eliminates the possibility of steam leaking from the valve stem.The bellows process is divided into hydroforming, roll forming, mechanical bulging, welding forming and deposition forming. A variety of processes are suitable for a variety of different working conditions.

Why Choose Lipin's Bellows Globe Valve

In many cases, manual steam valves used to use stuffed globe valves. Such valves have poor sealing performance, inflexible opening and closing, and short service life during use. Soon after the packing was replaced, steam leaked again, which affected the working environment and wasted a lot of steam. Choosing a Lipin bellows globe valve will solve all these problems.
  • Unique Sealing Design
    Unique metal bellows design, using bellows as the sealing element of the globe valve, bellows + packing double sealing design to eliminate the possibility of leakage.
  • Diverse Selection of Materials
    Going beyond traditional carbon steel to offer avant-garde options such as Inconel and Monel. Such materials serve as a bulwark against corrosion, especially in challenging environments.
  • Versatile Range of Applications
    Whether in the thermal oil, steam industry or chemical processing plants, Lipin's bellows-sealed stop valves are perfectly adapted.
  • No Compromise on Quality
    We strictly follow the design and inspection standards. From production to final product, we have professional engineers to check every step to ensure zero leakage of the valve.

Key Components of Bellows - Sealed Globe Valves

The Bellows Sealed Globe Valves mainly consists of the following seven parts. This component ensures that the globe valve remains efficient and stable during operation and maintains a zero leakage record.
  • Valve Body
  • Disc
  • Stem
    Facilitates valve operation.
  • Bellows
  • Actuator
  • Metal Seals
  • Bonnet
  • Advantages of

    Bellow Globe Valves

    • 01
      Strong high-pressure resistance
      The special metal bellows design gives the valve overall high strength and rigidity. This allows the bellows globe valve to withstand many extreme conditions such as high pressure, high temperature and external impact.
    • 02
      High-temperature working conditions
      Corrugated pipes have good elasticity and deformability. This allows the valve to adapt well to thermal expansion, contraction, vibration and other deformations.
    • 03
      Zero leakage design
      The bellows is connected to the valve stem through welding, which can form a double seal with the packing, truly achieving zero leakage.
    • 04
      Reduce maintenance costs
      There is no need to replace the filler frequently, and no additional material and labor costs will be incurred.
    • 05
      Stable system operation
      When replacing the packing of the traditional packing stop valve, the operation of the production line needs to be suspended, thereby causing losses, but the bellows stop valve does not need to replace the packing.

    Why Choose Bellows Globe Valves?

    The bellows seal globe valve has many advantages. The bellows globe valve is a new type of globe valve.

    The stem seal is a double seal design of bellows + packing. The sealing performance is more reliable than ordinary globe valves. The metal barrier formed by the bellows can prevent leakage, and the filler can also provide a sealing effect after the bellows fails.

    The application is safer, energy-saving, environmentally friendly, and has zero leakage. Meets international sealing standards. In addition, it can work in many extreme situations.

    About Lipin Bellows Globe Valve

    • Valve Body Type :
      Globe
    • Valve Body Material :
      When the valve body material is ordinary carbon steel, the valve disc material is usually CR13 series martensitic stainless steel (American Standard 410 and 420 stainless steel) or higher grade alloy. When the valve body material is stainless steel, the valve disc material is usually made of austenitic stainless steel (American standard SS304, SS316) that is not lower than the valve body material or a higher grade corrosion-resistant alloy material (Hastelloy, Monel) , Inconel alloy) etc.
    • Valve Stem Material :
      Valve stem material is basically the same as the valve disc, unless there are special requirements.
    • Seat Sealing Surface Material :
      Cladding stainless steel and cladding hard alloy (STL)
    • Bellows Material :
      Corrosion-resistant alloy materials such as Inconel and stainless steel, etc., ensure a tight seal and prevent leakage along the valve stem.
    • Pressure level :
      Class 150-2500 (ASME standards) or PN10~PN420
    • Actuator :
      Manual handwheel, Electric actuator, Pneumatic actuator
    • Temperature :
      Depends on the material used, but typically bellows can operate in a temperature range of -50°C to +400°C, although specific materials may alter this range.
    • Size:
      1/2'' to 24'' (DN 15-600)
