EN 16257:2012 (E) 4 Introduction The footvalve, also called emergency valve or internal security valve, the subject of this standard, is an internal self closing stop valve ensuring the primary containment to confine the dangerous substances within the tank when closed. It allows the flow of dangerous substances in the unloading direction, that is, from the tank compartment into the run-off pipe only when externally actuated. The non-pressure balanced footvalve shall be capable of allowing transfer of dangerous substances in the bottom loading direction through self-actuation by the hydraulic force of the loaded dangerous substances. The pressure balanced footvalve does not allow flow of dangerous substances in either the loading or unloading direction when not externally actuated, and stops the flow if the external actuation is interrupted or disengaged.
