Breakaway coupling device

A breakaway coupling device comprising:

• a female valve body, a plurality of boltholes extending therethrough, and a plurality of boreholes extending therethrough, wherein said female valve body further defines a first cavity traversing the female valve body;
• a male valve body, a plurality of flange pairs, and a plurality of boreholes aligned with the boreholes in the female valve body, wherein said male valve body further defines a second cavity traversing the male valve body;
• a plurality of tie bolts being attached to said female valve body through said plurality of boltholes, wherein said tie bolts are received by said plurality of flange pairs on said male valve body;
• a plurality of shear pins, wherein each one of said plurality of shear pin, intersects each flange pair and each one of said plurality of tie bolts at an angle perpendicular to said tie bolts thereby connecting said male valve body to said female valve body;
• a check valve being received by the first cavity and the second cavity;
• a plurality of guide pins closely received by the boreholes in the male valve body and the female valve body;
• and
• a channel being defined by said female valve body;
• wherein the guide pins are covered by a Teflon.RTM. sleeve.
