Abstract
A fluid dispensing apparatus for dispensing a viscous fluid from a source of viscous fluid onto a substrate. The dispensing apparatus includes an electrically operated, normally-opened, dispensing valve having an inlet in fluid communication with the source of fluid and a shut-off valve fluidly connected between the inlet of the dispensing valve and the source of viscous fluid. The shut-off valve has a normally-closed state interrupting fluid communication between the source of fluid and the inlet of the dispenser body, thereby inhibiting the normally-opened dispensing valve from dispensing fluid when power is removed from the dispensing apparatus.
