Welcome to Dutch Valve Vision - Your Trusted Partner for BELLOW SEALED VALVES
Bellow Sealed Valves – Leak-Free & Emission-Free Industrial Solutions
What is a Bellow Sealed Valve?
A Bellow Sealed Valve, also known as a Zero Leak Valve or Emission-Free Valve, is an advanced industrial valve designed to prevent leakage and ensure environmental and personnel safety. Unlike conventional valves, these feature a metallic bellow cartridge that expands and compresses with stem movement, creating a hermetic seal that eliminates the risk of process fluid escaping.
Why choose for Bellow Sealed Valves?
Bellow sealed valves are essential in industries where external leakage can lead to safety hazards, environmental pollution, or operational inefficiencies. They offer:
🔹 Zero Leakage – Ensures no emissions or fluid loss.
🔹 Long-Lasting Performance – Engineered for up to 50,000 operations.
🔹 Secondary Sealing System – Added safety with stuffing box packing.
🔹 Enhanced Durability – Forged or cast bodies with increased wall thickness.
🔹 Suitable for Extreme Conditions – Designed for high temperatures, aggressive chemicals, and hazardous gases.
Industries & Applications
Bellow sealed valves are used in various industries that demand high safety and reliability standards, including:
Chemical & Petrochemical: Ethylene, Phosgene, Vinyl Chloride Monomer (VCM), Isocyanates (MDI, TDI, HDI), Benzene (C₆H₆).
Chemical & Petrochemical: Ethylene, Phosgene, Vinyl Chloride Monomer (VCM), Isocyanates (MDI, TDI, HDI), Benzene (C₆H₆).
Oil & Gas: Safe handling of Liquefied Natural Gas (LNG), Hydrogen Sulfide (H₂S), and Ammonia (NH₃).
Energy & Power Generation: Steam and heat transfer fluids (hot oil, Dowtherm).
Semiconductor & High-Purity Processes: For ultra-clean applications.
Key Features & Benefits
Our high-performance bellow sealed valves are designed with the following critical features:
🔹 Metallic Bellow Technology – Forms a leak-proof barrier between the fluid and external environment.
🔹 Extended Bonnet Design – Provides thermal insulation and protects bellows from flow impact.
🔹 Multiple-Wall Hydro-Formed Bellows – Built for maximum durability and reliability.
🔹 Replaceable Disc Design – Reduces maintenance costs and increases service life.
🔹 Bubble-Tight Shutoff – Knife-edge metal-to-metal hard-faced valve seats prevent leaks.
🔹 Two-Piece Stem Design – Protects bellows from torque stress, ensuring longevity.
🔹 Fully Confined Gasket – Eliminates gasket blowouts for enhanced safety.
🔹 No Stem Bearings Required – Reducing operational friction and wear.
