Safety valve, pneumatic actuator, and vehicle

A safety valve for a pneumatic conduit (798), the safety valve (100) comprising:

• a valve body (120), arranged in the pneumatic conduit (798), the valve body including a pressure port (122) pneumatically connected to a pressure side (840) of the pneumatic conduit (798) and a release port (124) pneumatically connected to a release side (860) of the pneumatic conduit (798),
• a valve piston (140), arranged in the valve body (120) and axially movable along a valve axis (AV) relative to the valve body (120) between a release-side end position (SP1) on an axial side facing the release port (124) and a pressure-side end position (SP2) on another axial side facing the pressure port (122), and
• a valve piston spring (160) that pushes the valve piston (140) toward the pressure-side end position (SP2),
• wherein the safety valve includes a pressure-side gasket (130, 130′, 130″), which inhibits the air flow (AF) between the pressure port (122) and the release port (124) when the valve piston (140) is in the pressure-side end position (SP2).
