Areas of Application

The SZ Series Emergency Breakaway Coupling with cable control is designed to protect against unintended pull-aways of tank trucks, railcars, barges or ships. Loading arms and hose lines, conveying gases or liquid media, can be either newly equipped or retrofitted with the SZ Series.

Structure

Two non-return valves prevent product loss in case of emergency separation. Both coupler halves are held together with segments and a slide ring. A cable pull triggers the separation by flipping the levers out of their locked position. The NTS also is available with the proactive remote or hand separation.

Function

In a pull-off, the tensile force travels along the cable, leaving the hose or loading arm tension-free at all times. The levers are released, two non-return valves positively shut both ends, enabling the separation to occur. In contrast to most existing products, the SZ Series breakaways work independently from the working pressure and allow for a protective approach without the need to wait for an impact. With a proven track record of more than 25 years, the SZ Series Breakaway has earned an outstanding reputation of reliability in the industry.

Benefits

  • Protection of loading-arm components
  • Protection of loading facility
  • Spill prevention
  • Reconnectable

SAFER. Protects loading rack facilities, hoses and personnel by preventing damage and spills during a pull-away incident.

CLEANER. High value fluid and gas transfer is protected by two spring energized valves for maximum protection with a minimum of fluid loss.

FASTER. Immediate separation occurs at individually determined straight or angular pulling force. This non-destructive separation allows easy reassembly, with no shear pins, tools or spare parts.

  • Break Force does not change with system pressure or angle of pull!
  • Protects your system components by minimizing the amount of stress placed on your system. Pulling force is through cable NOT your hoses/piping.
