A movable valve member is provided for opening and closing the valve seat. A condition responsive unit is operatively associated with the valve member to move the valve member relative to the valve seat in response to the conditions sensed by the condition responsive unit. A snap opening unit is interconnected to the valve seat to rapidly move the valve seat away from the valve member when the valve member has initially opened the valve seat a certain amount.
