1. A 2/2-way seat valve, comprising:
a joint valve body integrating a pressure limiting function and a thermal overpressure protection;
an inflow hole and an outflow hole in the valve body;
a valve piston being coupled to and actuated by a magnetic drive and interconnecting and separating the inflow hole and the outflow hole to and from, respectively, each other in a fluid-conveying manner, the magnetic drive having an armature piston mounted for longitudinal movement in a pole tube, the armature piston being electromechanically operated by an energizable solenoid so as to lift the valve piston off a valve seat in a valve housing being a part of the valve body and so as to open a fluid path from the inflow hole to the outflow hole; and
a linkage part and a control rod being connected to the armature piston and moving the armature piston, the linkage part extending out of a pressurized area of a fluid volume enclosed in the valve housing and in the pole tube, being a further part of the valve body and being coupled to and movable counter to an action of an energy accumulator in the valve body.
