The Manual On Tank Valve is attached to a high- pressure hydrogen tank that stores the hydrogen used to power fuel cell vehicles at a maximum of 87.5 MPa. The valve measures the temperature of the gas inside the tank and has the function to safely release the gas from the tank through a Temperature pressure release device (TPRD) at 110°c outer temperature.
The valve can be closed manually with a manual stop valve. In closed position the inlet and outlet pressure are blocked. In case of pipeline rupture after the MOTV an excess flow valve reduces the maximum outcoming flow.
