ABSTRACT:
A pressure relief valve for flowing media has a closing element (6), whose closing force can be set with both the setting of the closing force and the brief release of the closing element (6) performed with a single setting element. Teeth (22, 23) are provided, by which the threaded sleeve (3) can be actuated such that it can perform a rotary movement and a lifting movement can be performed between the handwheel (2) and the threaded sleeve (3). The teeth are provided between a pin (21) of the handwheel (2) for setting the closing force and a threaded sleeve (3). The closing element (6) is connected to the handwheel (2) such that the closing element (6) follows the lifting movement of the handwheel (2).
