Bellow Seal Globe Valve, Angle, DIN

 angle bellow seal globe valve

The angle bellow seal globe valve is a globe valve with a special structure. Its inlet and outlet are designed at a 90-degree angle. It mainly uses a bellow as the key sealing element and serves as a moving part for cutting off, distributing, and changing the flow direction of the medium.

This valve is composed of components such as the valve body, bonnet, disc, stem, bellow, and stuffing box. The bellow is automatically roll-welded between the fluid medium and the atmosphere to form a metal barrier, playing a sealing role.

Main features of angle bellow seal globe valve.

  • Double-sealing design: The angle bellow globe valve adopts a double-sealing design of bellow and packing. If the bellow fails, the valve stem packing can also play a sealing role, further improving the safety of the valve.
  • Space-saving: The 90-degree right-angle outlet design of this valve saves the 90-degree elbow, reducing material consumption and installation space. It is especially suitable for installation at the corners of the pipeline system.
  • Precise control: By adjusting the opening degree of the valve disc, precise control of the medium flow rate can be achieved to meet different process requirements.
  • Corrosion resistance and high-pressure resistance: Key components such as the valve body, valve seat, and valve core are made of corrosion-resistant materials such as high-quality stainless steel, having good corrosion resistance and high-pressure resistance capabilities.
  • Long service life: The valve disc with a conical design has a “scraping effect”, which can automatically remove surface impurities, ensuring reliable sealing of the valve disc and a longer service life.

What are the advantages of an angle bellow seal globe valve?

Angle bellow seal globe valves offer several advantages, mainly sealing performance, space – saving design, corrosion resistance, and flow control. The details are as follows:
Excellent Sealing Performance: These valves feature a double-sealing design, typically with a bellow as the primary seal and packing as a secondary seal. This design ensures reliable sealing, minimizing the risk of leakage. The bellow forms a tight barrier between the valve stem and the process fluid, even under high – pressure and high – temperature conditions.
Space-Saving Design: The angle – type design of these valves, with a 90 – degree outlet, allows for a more compact installation in pipeline systems. It is particularly suitable for corner installations, reducing the overall space occupied by the piping system and potentially eliminating the need for additional elbow fittings.
Good Corrosion Resistance: The materials used in the construction of angle bellow seal globe valves, such as stainless steel and various alloys, provide excellent resistance to corrosion. The bellow, in particular, isolates the valve stem from the corrosive medium, further enhancing the valve’s durability and reliability in harsh chemical environments.
Precise Flow Control: Angle bellow seal globe valves are designed to provide precise control over the flow of fluids. The valve stem’s movement and the conical shape of the valve disc allow for fine – tuning of the flow rate, making these valves suitable for applications where accurate flow regulation is required.
Reduced Maintenance: The reliable sealing mechanism and durable construction of angle bellow seal globe valves contribute to reduced maintenance requirements. The bellow’s integrity helps prevent leakage, which can lead to costly repairs and downtime. Additionally, the use of high – quality materials reduces the need for frequent replacements due to wear and corrosion.
