Designed specifically to minimize spillage and damage associated with drive/pull away incidents. Also allows rapid removal of the mobile tankage in emergency situations. The coupling automatically senses an excessive load, closes its valves and then permits disconnection. The coupling has exceptionally high flow rates / low pressure drop and operate independently of shut off safety systems and do not require an external power source. These couplings are easy to handle and do not require removal from the hose/loading arm for resetting or maintenance. These safety breakaways boast extremely quick closing time, with minimal loss of media.
