Valves for controlling the release of a substance, include a housing having an inlet for connection to a source of the substance, an outlet, and a passage extending therebetween. The passage is enclosed by a ceramic disc and means are provided to apply an electrical pulse to the disc to break the disc and so connect the inlet to the outlet. The methods include containing the substance in a container, connecting the container to a valve; and applying an electrical pulse to the disc to break the disc and connect the inlet to the outlet. The valves and methods are particularly suited, but not limited, to the control of substances such as pressurised fire extinguishing media.
