Bellow Seal Globe Valve

A Bellow Seal Globe Valve is a construction that is a kind of control valve that seals the valve stem components using bellow.

We are leading Bellow Seal Globe Valve manufacturer in Mumbai, India. A Bellow is contained within the valve, and the lower end of the stainless-steel / nickel alloy Bellow is welded to the stem to prevent the stem from being eroded by system fluid. The other end is inserted between the valve's body and cover to form a permanent seal.

This double seal structure prevents leakage; in the event that the bellow collapse, the stem packaging will prevent further leakage. The bellow are welded to the valve stem to provide steady operation and to eliminate valve stem vibration caused by the valve insert movement.

  1. No Bellow Torsion.
    The non-rotating stem prevents Bellow  Torsion and guarantees high cycle life on all Bellow-Seal Valves.
  2. Bellow with long cycle life.
    Designed for High pressure/temperature applications and successfully tested as per MSS SP-117 / API 598.
  3. Minimal Torque.
    Because of the non-rotating stem, a central grease fitting is used to lubricate the stem nut and, for high-pressure valves, a stem thrust bearing.
  4. Stem / Gland Seals
    a. When open, the backseat (stem bevel) guards against line pressure.
    b. Gland Packing (Graphite / PTFE)
  5. Zero Maintenance Operating and maintenance costs are significantly decreased as a result of the longer service life.
  6. Hermetic Sealed (100% Emission Free).
    In most designs, Body-Bonnet welds create a hermetically sealed vessel. (As per requirement)

    The fire-safe design adds an extra layer of protection, while their suitability for vacuum service makes them versatile. 
    Our valves also offer easy replacement and incorporate additional measures for odor and safety enhancement.

  • How does a Bellow Seal Valve work?

    The bellows element in the valve expands and contracts with the movement of the valve stem, ensuring a tight seal even in challenging conditions. This design eliminates the need for external packing and minimizes the risk of leaks.

  • What are the benefits of using Bellow Seal Valves?

    Bellow Seal Valves provide excellent leak-tightness, reduced fugitive emissions, and improved safety. They are suitable for applications involving corrosive, toxic, or high-temperature fluids.

  • Can Bellow Seal Valves handle high pressures and temperatures?

    Yes, bellows seal valves can be designed to handle a range of pressures and temperatures. It's important to select the appropriate bellows material and valve design based on the specific operating conditions.

  • Can Bellow Seal Valves be used for both on-off and throttling applications?

    Yes, bellows seal valves can be used for both on-off and throttling applications. Their reliable sealing capability makes them well-suited for isolation as well as precise flow control.

  • Can Bellow Seal Valves be automated?

    Yes, Bellow Seal Valves can be automated using various types of actuators, such as electric, pneumatic, or hydraulic. Automation allows for remote control, integration into control systems, and enhanced safety.

  • How do I maintain a Bellows Seal Valve?

    Regular inspection and maintenance are essential to ensure the longevity of bellows seal valves. Check the condition of the bellows, ensure proper sealing, and follow manufacturer recommendations for cleaning and maintenance.
