OPW Engineered Systems
NTS-PU (direct pull) Series Safety Breakaway Coupling

Areas of Application

The 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 and 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.

Function

While 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.
