How the valve works

The equalization valve addresses the pressure disparity with a miniature hydraulic cylinder and a few machined parts. The miniature hydraulic cylinder is the heart of the valve. It responds to both gases to determine the amount of gas released from the oxygen side, based upon the pressure of both gases in relation to each other. The cylinder opens and closes an outlet port for the oxygen. 

When the pressure on the oxygen side rises higher than the hydrogen pressure, the oxygen gas pushes in one direction against the cylinder, which is being pushed in
