A thermal relief valve is a liquid-only relief due to expansion of a liquid with increased temperature.
A safety valve relieves pressure due to a gas.
It should be noted that "safety valve" is a general term which could refer to Pressure Relief Valves (PRVs) or Pressure Safety Valves (PSVs), terms which are used synonymously in some industries (such as the petroleum industry) to refer to all relief devices in general.

What is Difference between relief valve and safety valve?
Relief valve always position in the suction line in oreder to relief the extra pressure, while safety valve is always placed at discharge line to release excess pressure.I would take that one step further by stating that a " RELIEF VALVE" is one that is "meant" to be lifted off its seat, as opposed to a "SAFETY RELIEF VALVE" which is not!DIFFERENCE BETWEEN RELIEF VALVE AND SAFETY VALVE:1. Releif valve is applicable in the fluid system.safety valve is applicable in the gaseous system.2.Relief valve opening is directly proportional to the pressure rise.Safety valve opening is will happen at after reaching the setpressure.3.Mode of relif vlave line is again connected to the suction.But in the safety valve is just vent-out there is no connection tosuction.

Difference between rapture disk and psv and relife valve?
Rupture disks and pressure safety valves (psvs) are both types of relief valves. Rupture disks are thin sheets of metal that break at a designated pressure and can only be used one time. Pressure safety valves also relive at a specified pressure, but work by a spring and can relieve multiple times with little or no damage to the relief device.
