Safety Breakaway DevicesSZ Series (Cable Release) Breakaway CouplingAreas 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•Protectionofloading-armcomponents

•Protectionofloadingfacility

•Spillprevention

•Reconnectable

SZ Series Breakaway CouplingInstallation ExampleWhen the line system is subjected to an unprecedented load, the levers swing out by the cable. The slide ring is displaced and the segments are released. Then the two body halves separate and the two spring-loaded valves immediately shut both hose ends.

SZ Loading Arm Marine Installation Example

Note: The length of the SZ cable must be shorter than the maximum movement of the loading arm hose in order to trigger the separation.

Safety Breakaway Devices nTS-PU Series (Pull-Away) Breakaway Coupling

Areas of applicationThe OPW Engineered Systems NTS-PU Series Breakaway protects loading facilities, hoses and prevents spills at the same time. Separation occurs by a simple pulling force on the hose line. It finds its application in fluid and gas transfer. The OPW Engineered Systems NTS-PU is axially built into hose lines (see example design at right).

Construction of the NTS-PU Series The NTS-PU consists of two halves (Adaptor & In-line), each equipped with spring-loaded valves. A straight or angular pulling force on the hose triggers the separation. To protect the hose line from damage, the separation force of the NTS-PU can be individually adjusted.

FunctionWhile coupled, the valves of the Emergency Release System NTS-PU are open. Upon a pre-determined pulling force, the separation occurs. Both valves close, thus preventing spills and protecting the loading station at the same time.

The NTS-PU allows for a spare-part-free, non-destructive separation – no shear pins involved and no destruction.

After depressurizing and emptying the hose, the NTS-PU can be reassembled easily, without tools or spare parts.
