Operation & Maintenance Guidelines
Smooth Spiral Rail Connection: Unlike conventional Dry Disconnect Coupling designs, male and female components connect via a smooth spiral rail. This design:
Minimizes dead space in the coupling pathway, reducing media residue buildup.
Simplifies cleaning and sterilization processes, critical for sanitary applications.
Versatile Sealing Options: Compatible with high-performance gaskets (FKM, NBR, FFKM, PTFE) to ensure leak-tight seals across diverse chemical and temperature conditions.
Robust Pressure Rating: Operates reliably within a working pressure range of 10–25 bar, suitable for most industrial process demands.
Flexible End Connections: Available with flange or threaded end connections for seamless integration into existing piping systems.
Core Features & Applications
Automatic Leak-Tight Operation: The coupling features an interlocking valve mechanism that automatically opens upon connection and closes upon disconnection. This ensures a "dry break" with zero leakage, preventing environmental contamination and safety hazards.
Versatile LPG Applications: Suitable for both gas phase and liquid phase pipelines handling propane, butane, and other similar hydrocarbons. Ideal for use in chemical plants, fuel depots, and logistics terminals.
Robust & Reliable Design: Equipped with high-performance FPM (Fluorocarbon) gaskets, the coupling operates reliably within a pressure range of 10–25 bar. The durable metal construction resists corrosion and withstands frequent use.
Safety-Focused Ergonomics: Designed with distinctive high-visibility handles for easy identification and smooth operation. The secure threaded end connection ensures stability even under high-pressure conditions.
