Abstract
A safety device for a linearly actuated process valve and a system including the safety device are disclosed. The safety device includes a housing, a piston rod which is mounted in the housing so as to be linearly displaceable and connectable to the process valve, and a piston which is connected to the piston rod. Furthermore, at least one spring is arranged in the housing of the safety device. The spring is clamped between the piston and an end face of the housing. The safety device also has a first mechanical interface by way of which the safety device can be detachably connected to a linear actuator.

A safety device for a linearly actuated process valve, comprising:
- a housing;
- a piston rod which is mounted in the housing so as to be linearly displaceable and connectable to the process valve;
- a piston which is connected to the piston rod;
- at least one spring which is clamped between the piston and an end face of the housing;
- and
- a first mechanical interface by way of which the safety device is detachably connected to a linear actuator;
- and
- a pressure compensation device which is designed to equalize the pressure between the surroundings and an interior of the safety device,
- wherein the pressure compensation device is arranged in the piston rod.
