Abstract
A valve having an over-travel spring that does not necessarily need an excessively additional force to further close the valve once its valve seal comes into contact with a valve seat. The feature may be achieved by inserting an over-travel spring between a plate or stop attached to a valve stem, and a valve seal. The valve seal may come in contact with a valve seat when the valve is closed with movement of the valve stem. The valve stem may continue to travel after contact between the valve seal and the valve seat without additional force, other than that added by compressing the over-travel spring, and with a proof-of-closure sensor indicating valve closure. The valve stem may be moved in either direction for closing and opening the valve with an assist, such as a solenoid or other mechanism.
