NTS-PU Series (Pull-Away)
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.
Material: Stainless Steel (316), Anodized Aluminum
Others available upon request
Function
While coupled, the valves of the Emergency Release
System NTS-PU are open. Upon a pre-determined pulling
Seals: Fluorocarbon, EPDM, Chemraz®
force, the separation occurs. Both valves close, thus Pressure Ratings: 360 psi for all sizes (Alu 232 psi)
preventing spills and protecting the loading station
at the same time. Connections: FNPT or Flange (TTMA/150/300 ANSI) 1", 2", 3", 4"
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.
