Abstract
A valve includes a valve body that defines a flow passage, a valve seat in the flow passage, a valve element that is initially in a closed position with respect to the valve seat to block flow through the flow passage, a bonding material that secures the valve element in the closed position, and at least one heater adjacent the valve seat and operable to heat the bonding material at least to a temperature at which the bonding material releases the valve element to move to an open position with respect to the valve seat to open flow through the flow passage.
