Gall Thomson Petal Valve Marine Breakaway Coupling

The Gall Thomson Petal Valve Marine Breakaway Couplings minimise offshore hose transfer oil spills which are caused by tanker breakout or internal pressure surge incidents.The Petal Valve Marine Breakaway Coupling was specifically designed to aid the safe transfer of heavy fuel products.It provides an identified safe parting point in the marine hose transfer systems which activates in the event of an undue overload during tanker loading or discharging or an extreme pressure surge generated by the sudden, inadvertent closure of a valve downstream of the MBC. The separation immediately relieves the acute tension in the transfer system and it will safely shuts down the product flow.The design parting load at which the unit activates is determined by the design parameters of the subject terminal operation, the consultation with the world’s leading marine hose manufacturers and many years of field experience.The Petal Valve MBC design has a full, smooth and uninterrupted bore which provides zero headloss, eliminating pressure drop during product transfer or the necessity to increase power at the pumps to maintain original design flow rate. The internal components are protected. The fully sealed sleeved bore isolates the internal components of the device from the product flow or sea water, ensuring considerably reduced maintenance costs
