1. Key Production Features of Quick Closures

1. Short Operating Time: The EMT Quick Closure utilizes an innovative locking-ring quick opening mechanism with an integral scalable locking ring structure. This design significantly reduces the time required for opening and closing compared to other types of quick closures. A single operator can complete the process in under one minute with a force of less than 200N, streamlining operations and enhancing productivity.
2. Self-Tightening Lip Seal Structure: The closure features a unique self-tightening lip seal that ensures a secure and reliable seal under varying pressure conditions. This design minimizes the risk of leaks, enhancing safety and performance even in high-pressure environments.
3. Safety Lock System with Self-Locking Function: The safety lock system includes a self-locking mechanism that provides critical safety features:
   • Pre-Booster Locking: Before pressure is boosted, the fast-opening blind and locking structures can secure the equipment, preventing accidental operation unless the appropriate lock position is reserved.
   • Post-Unloading Pressure Relief: Once unloading is complete, the system ensures that the inner pressure is fully relieved before the blind flange cover can be opened. This secondary pressure relief mechanism prevents safety hazards resulting from improper operations.

2. Technical Specifications

• Design Pressure: Rated for pressures between 1.6 MPa and 30 MPa, making it suitable for demanding high-pressure applications.
• Corrosion Allowance: Designed with a 2mm corrosion allowance to ensure durability and longevity in corrosive environments.
