Key Features of Quick Actuating Closures

  1. Rapid Opening and Closing: These closures are designed to be operated quickly, often in a matter of minutes or seconds, allowing for efficient access to the contents of the vessel.
  2. Safety Mechanisms: Quick-actuating closures typically incorporate safety features to prevent accidental opening or closing. These can include locking mechanisms, interlocks, and indicators to ensure that the closure is properly secured or released.
  3. Pressure and Leak-Tight Sealing: When closed, these closures create a pressure-tight and leak-proof seal to maintain the integrity of the vessel and prevent the release of contents.
  4. Ease of Use: Quick-actuating closures are designed to be user-friendly and require minimal tools or specialized equipment for operation.
  5. Variability: They come in various sizes and designs to accommodate different vessel types, sizes, and pressure ratings.
  6. Application: They are commonly used for applications such as pipeline pigging, inspection, maintenance, and cleaning of tanks, vessels, and other pressure-containing equipment.
  7. Materials: These closures are typically constructed from materials that are suitable for the contents and conditions of the vessel, often including corrosion-resistant metals and elastomers.


Advantages of Quick Actuating Closures

  1. Quick Operation: Equipped with an integrated scalable locking-ring structure, our Quick Actuating Closure drastically shortens the operation time compared to other types of quick-opening closures. It enables a single operator to easily complete the opening and closing process within one minute using less than 200N of force.
  2. Enhanced Sealing: Thanks to our unique self-tightening lip seal structure, we ensure a safer and more reliable sealing process of quick actuating closures.
  3. Safety Lock System: Our closure features a safety lock system with a self-locking function. This system ensures that all operational parts, including the quick-opening blind and the locking structure, are locked before pressurizing the equipment. Without the lock in the reserved position, the equipment cannot be pressurized. After depressurizing the equipment and before opening the blind flange cover, the system ensures complete pressure relief inside the container. This double pressure relief mechanism helps avoid safety issues due to incorrect operations.
