Quick couplings for High pressure

Description

High-Pressure Quick Couplings

The High-Pressure Quick Couplings by Stucchi are the ideal choice for applications requiring high performance and safety under extreme operating conditions. Designed with flat-face valves, these couplings minimize fluid loss during disconnection and prevent air inclusion in the hydraulic circuit. This makes them particularly suitable for sectors such as hydraulics, earth-moving equipment, agriculture, and the chemical industry.

Main Features:

• High-quality materials: carbon steel treated with Cr3 for enhanced resistance.
• High pressures: support up to 700 bar, ensuring reliability in high-stress applications.
• Operating temperatures: compatible with a range from -20°C to +100°C, ideal for extreme environments.
• Safety system: automatic locking prevents accidental disconnections, increasing operational safety.
• Compact and modular design: easy integration into various hydraulic systems with threads available in BSP and NPT.
• Flat-face valves: significant reduction of fluid loss and contamination risks.

These couplings have been tested to withstand 100,000 pressure cycles, demonstrating superior durability. Thanks to their reliable performance and optimized design, they are an indispensable solution for those seeking efficiency and robustness in high-pressure hydraulic systems.

There are two types of high-pressure quick couplings available: the A-HP series and the IV-HP series.

• A-HP is the series of flat-face quick couplings dedicated to high-pressure hydraulic applications up to 700 bar. The couplings are made of ultra-high-strength carbon steel. Their characteristic of zero fluid loss during coupling and uncoupling phases, non-interchangeability with couplings operating at lower pressures, and the automatic safety system preventing accidental uncoupling make the “A-HP” series very safe. For this reason, the “A-HP” series is used and appreciated in applications where achieving high operating pressures with maximum safety is necessary.
• IV-HP is the series of screw-to-connect quick couplings with ball seals for high-pressure hydraulic applications up to 700 bar. The couplings are made of ultra-high-strength carbon steel with zinc plating surface treatment. They are interchangeable with similar couplings available on the market and are primarily used on jacks and hydraulic cylinders.
