ABSTRACT A high-pressure relief valve, which has a housing a housing upper section and installed spring assembly, valve seat and seat receiving bore, valve head, shaft, shackle, and setting drive, for releasing liquid hot separation product, (in particular from the hydrogenating separation of coal), the separation product containing solids in the form of ash, catalyst and unconverted coal components. Improved service life of the components subject to wear, good control characteristics, and good sealing properties are achieved. The throttle passage between the valve seat 10 and the valve head 11 is configured as a gap between two flat bodies. Lifting movement of the valve head 10 is achieved by operation of the setting drive 4 and conversion of the motion of the setting drive 4 into rotary movement of a nut 3 which is in turn converted by an internal screw or worm element joined to the valve shaft 2 to a defined linear movement of the shaft.
