Dixon MSBC400SS MannTek Safety Breakaway Coupling Marine Female NPT x Female NPT

Applications

• Coupling is designed to minimize spillage and damage associated with pull away incidents.
• Typically used in ship-to-offshore platform and ship-to-ship product transfer operations

Available Options

• Also available in 150# Flange BSP thread, DN Flange, 300# ASA Flange, Grooved Ends or any combination thereof. Consult Dixon for more information.
• Optional Non-closure Design available, consult Dixon for more information. The non-closure design is an economical alternative which allows the coupling to break away due to pull-away/drive-away incidents thus protecting piping systems and equipment. The design allows spillage of product in these instances due to the lack of valving in the coupling. Useful applications where non-hazardous product is being conveyed and where there are no environmental concerns.

Construction

• 316 Stainless Steel body
• FKM O-rings

Features

• Designed to be installed within a hose string where the coupling will have a length of hose attached to both sides
• Coupling automatically senses an excessive load, closes the valves and disconnects
• Release is executed when force causes bolts to break

How It Works

• The safety breakaway valve consists of two halves, each with a valve that has an O-ring seal. When the safety breakaway couplings separate, it allows the valves to close. The two valves close rapidly, minimizing exposure to personnel and the environment.
• Safety breakaway couplings have three external break bolts. In the case of axial tension all of the bolts take up the force corresponding to the break force on the hose with a safety margin.
