The valve has an automatic closure actuated by extraneous energy of electrically, pneumatically or hydraulically operated electric motor. A safety closing device is actuated independent of the automatic closure. The motor is controllable by a float assembly (16) arranged in the valve. The float assembly includes a magnet (19), which moves along with the assembly. A reed contact (20) arranged at the valve is closable by the magnet, where the contact is coupled with the motor and is provided vertically above a moving direction of the magnet. |
