Abstract
A valve assembly includes a valve with a valve body and chamber. A poppet with a stem and piston is slidably engaged inside the valve body. A poppet release mechanism is included for releasing the poppet from a closed position. A mechanism cover is attached to the valve body. A safety mechanism with a pin, spring, and lever is included for preventing the poppet from moving into a fully open position. A first end of the pin extends into the chamber into a pathway of the poppet and a second end of the pin extends into the valve body of the valve. The spring is positioned between and in contact with the pin and the mechanism cover to bias the pin toward the poppet. A first end of the lever is pivotably attached to the pin and a second end of the lever extends out from the valve body.
