Abstract:
A gas cylinder valve 2 is able to be opened by application of a pilot gas pressure. In certain embodiments the gas cylinder valve 2 is usable with a yoke 8 for engaging with a valve assembly of a gas cylinder 1, the yoke comprising a pilot gas passage 28 able to connect a pilot gas chamber 37 in the cylinder valve assembly to a source of pressurized pilot gas and the cylinder gas port of the gas cylinder valve to an external cylinder gas passage. The valve and yoke enable the tamper-resistance of a gas cylinder to be improved.
