Abstract

A flush valve includes a housing having a first end and a second end, a piston stem extending between the first end and the second end, a piston stem fore end coupled to the piston stem, a first O-ring and a second O-ring defining a control chamber therebetween, and a solenoid valve in fluid communication with the control chamber. The piston stem fore end is positioned toward the second end when in a closed position. In an energized state, the solenoid valve charges a pressurized gas into the control chamber, pushing the piston stem toward the first end and into an open position.
