Abstract
A two-stage valve system includes a safety latch configured to at least partially cover an actuation lever, such as a foot pedal, to prevent inadvertent operation of the actuation lever. The safety latch needs to be lifted to a certain level to gain access to the actuation lever in a first stage, and then the actuation lever is operated to actuate a valve assembly in a second stage.
