What is the difference between Petal and Flip-Flap valves?

Gall Thomson offers Petal Valve and Flip-Flap Valve Marine Breakaway Couplings. Petal valves are associated with higher viscosity products, including crude oil, while Flip-Flap designs are intended for lower viscosity products such as kerosene and LPG. Final selection depends on the full transfer specification.
