Disengageable valve backseat system and method

A valve assembly, comprising:

• a valve drive train;
• a valve stem;
• a bonnet cap;
• a first eutectic ring, wherein the first eutectic ring, when in a first state, blocks movement of the valve drive train, and wherein the first eutectic ring, when in a second state, enables the valve drive train to move;
• and
• a second eutectic ring, wherein the second eutectic ring, when in a third state, blocks movement of the bonnet cap, the valve drive train, or the valve stem, and wherein the second eutectic ring, when in a fourth state, enables the bonnet cap, the valve drive train, or the valve stem to move.

A method for disengaging a valve stem from a backseat profile of a bonnet of a valve assembly, comprising:

• providing a valve assembly, the valve assembly including a first eutectic ring at a first position and a second eutectic ring at a second position;
• melting the first eutectic ring and the second eutectic ring to a flowable state;
• and
• causing a bonnet cap to be driven in a direction after the first eutectic ring and the second eutectic ring flow, at least partially, out of the bonnet cap when in the flowable state.
