  Bellow Seal Valves Manufacturer in USA

  SVR Global is a leading bellow seal valves manufacturer in USA, delivering API, ASME, and ISO-certified valves, we supply high-performance bellow seal valves engineered to withstand the toughest conditions.In industries where safety, reliability, and zero leakage are critical, bellow seal valves are the preferred choice. Designed with a metallic bellows that provides a hermetic seal around the stem, these valves eliminate leakage and protect against the escape of hazardous, toxic, or flammable fluids.

  What are Bellow Seal Valves?

  Bellow seal valves are specially designed valves that use a metallic bellows instead of conventional packing to prevent leakage from the stem area. The bellows expand and contract with stem movement, maintaining a tight seal throughout the valve’s life.

  This makes them the ideal choice for handling toxic, flammable, radioactive, or high-purity media, where even minimal leakage can cause safety hazards or contamination.

  Advantages of Bellow Seal Valves

  ·        Zero Stem Leakage – Prevents fugitive emissions and ensures maximum safety.

  ·        Extended Service Life – Bellows reduce wear and tear, minimizing downtime.

  ·        Safe for Hazardous Media – Handles toxic, radioactive, or flammable fluids with reliability.

  ·        Energy Efficient – Prevents product loss and improves system efficiency.

  ·        Environmentally Friendly – Reduces greenhouse gas leakage, supporting emission control goals.

  ·        Low Maintenance – Long-lasting sealing eliminates frequent repacking requirements.

   

  Types of Bellow Seal Valves -

  1. Bellow Seal Globe Valve – Precise throttling with zero leakage.
  2. Bellow Seal Gate Valve – Full shut-off for isolation services.
  3. Bellow Seal Stop Valve – Designed for high-pressure and temperature service.
  4. Bellow Seal Angle Valve – Ideal for systems requiring 90° directional changes.
  5. Cryogenic Bellow Seal Valves – Engineered for LNG and low-temperature applications.

   

  Parts of Bellow Seal Valves-

  ·        Valve Body & Bonnet – Forged or cast in carbon steel, stainless steel, duplex, or alloy steel.

  ·        Bellows – Stainless steel, Inconel, or Hastelloy for durability.

  ·        Stem – Rising or non-rising design, linked directly to the bellows.

  ·        Disc/Plug – Provides sealing and flow regulation.

  ·        Seat Rings – Hardened for leak-proof shut-off.

  ·        Packing & Gland – Secondary sealing for additional protection.

  ·        Actuator/Handwheel – Available in manual, pneumatic, or electric actuation.

   

  Industries Using Bellow Seal Valves -

  ·        Oil & Gas – Prevents leakage in hydrocarbon and gas pipelines.

  ·        Power Generation – Steam isolation in high-pressure boiler systems.

  ·        Petrochemicals & Chemicals – Safe handling of corrosive and hazardous media.

  ·        Cryogenics – LNG storage and distribution facilities.

  ·        Marine & Offshore – Used in offshore rigs and shipboard systems.
