The Gromelle MLDB quick coupling socket with shut-off valve is a high-performance solution designed for demanding applications where absolute cleanliness and reliability are essential. Manufactured from premium AISI 316L stainless steel using the advanced VIM-VAR vacuum melting process, it guarantees exceptional purity and durability, making it the preferred choice for industries such as nuclear energy, food processing, pharmaceuticals, semiconductor manufacturing, and even the production of high-end fragrances. Its flat-face internal thread design minimizes fluid loss and contamination risk, while the integrated safety pin prevents accidental disconnection, ensuring secure and stable operation. Engineered to operate under a working pressure of 25 bar with a safety factor of 4:1, this coupling delivers consistent performance in critical environments. Depending on the sealing material, it withstands extreme temperatures ranging from -20°C to +200°C with Viton or from -40°C to +150°C with EPDM, offering flexibility for diverse industrial conditions. Not intended for connection or disconnection under pressure, the MLDB coupling is the ideal choice for professionals who value precision, safety, and uncompromising quality in their installations.
