Bellow Seal Globe Valve Manufacturer in USA

SVR Global is a trusted bellow seal globe valve manufacturer in USA, supplying API, ASME, and ISO-certified valves. With advanced engineering, high-quality materials, and strict quality control, we deliver valves that ensure safety, efficiency, and compliance with international standards.

When industrial plants in the USA demand zero leakage, long service life, and superior sealing performance, bellow seal globe valves become the preferred choice. These valves are specially designed with a metallic bellows element that eliminates gland leakage, ensuring reliability in critical service conditions.

What is a Bellow Seal Globe Valve?

A bellow seal globe valve uses a metallic bellows welded to the valve bonnet and stem, forming a hermetic seal to prevent leakage from the stem area. This design eliminates fugitive emissions, reduces maintenance, and enhances operator safety. Unlike conventional globe valves with packing, bellow seal valves offer a leak-tight guarantee even in toxic, flammable, or hazardous applications.

Advantages of Bellow Seal Globe Valves -

·       Zero Stem Leakage – Hermetic seal prevents fugitive emissions.

·       High Safety – Ideal for handling hazardous, flammable, or toxic media.

·       Extended Service Life – Reduced wear and tear compared to traditional packing.

·       Maintenance-Free Operation – Less need for frequent gland adjustments.

·       Dual Sealing Design – Bellow seal plus packing ensures double protection.

·       Energy Efficiency – Minimizes media loss and improves system reliability.

·       Wide Application Range – Handles steam, oil, gas, chemicals, and condensates.

Types of Bellow Seal Globe Valves

·       Straight Pattern Bellow Seal Globe Valve – Standard type for linear flow control.

·       Angle Type Bellow Seal Globe Valve – Suitable for systems with directional change.

·       Y-Pattern Bellow Seal Globe Valve – Lower pressure drop, ideal for high-pressure applications.

·       Cryogenic Bellow Seal Globe Valve – Designed for LNG, liquid nitrogen, and low-temperature services.

·       Actuated Bellow Seal Globe Valve – Available with electric or pneumatic actuators for automated control.

Key Parts of Bellow Seal Globe Valves

·       Valve Body – Manufactured from WCB, CF8, CF8M, Alloy Steel, or Duplex.

·       Bellows Element – Stainless steel or Inconel for flexibility and tight sealing.

·       Disc/Plug – Ensures precise throttling and flow regulation.

·       Seat – Hard-faced or soft-seated depending on service requirements.

·       Stem – Connects actuator/handwheel to disc, supported by bellows.

·       Bonnet – Houses the bellows assembly for protection.

·       Packing & Gaskets – Provide backup sealing.

·       Actuator/Handwheel – Manual, gear, electric, or pneumatic options.
