A pressure and temperature valve comprising a pressure relief valve (100) and a temperature probe (200). The pressure relief valve comprises a valve seat (14) and a valve member (20) arranged to rest in contact with the valve seat to close the valve and to be lifted off the valve seat to open the valve. The temperature probe (200) comprises a housing (52), a volume of expansion material (62) within the housing, a piston (64) slidable within the housing and arranged to be moved in a first direction by expansion of the expansion material, and in a second direction opposite to the first direction on contraction of the expansion material. A lift rod (90) is arranged to be moved by movement of the piston (64) in the first direction thereby to move the valve member (20) to open the valve.
