Tip-resistant valve plugs

A tip-resistant valve plug comprising a valve head, first and second retention legs, and an anti-tip fin, wherein:

• the valve head comprises a continuous partition defining a fluid barrier between a sealing side and an external side of the valve head;
• each of the first and second retention legs extend from a leg base positioned at the sealing side of the valve head to a distal end of the retention leg;
• each of the first and second retention legs comprise a plug catch configured to interfere with an inside diameter of a fluid flow orifice or a pressure relief spring;
• the respective distal ends of the retention legs are spaced apart from one another;
• the anti-tip fin extends from the sealing side of the valve head in a direction of the respective distal ends of the retention legs;
• and
• the anti-tip fin comprises a groove extending along the anti-tip fin that allows the valve head to flex along a longitudinal fin axis.

• and
• the anti-tip fin extends from the sealing side of the valve head to a fin height dimension that is greater than a relief spring compression dimension caused by the tip-resistant valve plug moving from the closed position to an open position.
