Abstract
A shutoff valve with a spring-loaded valve disk. The spring, designed as a tension or pressure spring is arranged outside of the valve housing, where a pivoting arm is attached to the actuating shaft. One end of the arm remote from the shaft is engaged by the spring. The other end of the spring is supported on an abutment mounted on the outside of the valve housing. The driver and the abutment are arranged in such a way that in the closed position, an imaginary connection line extends between the abutment and the driver with a lateral displacement transverse to the longitudinal shaft axis extending in the direction of closing the valve. The operational state of the spring is always visible so that a damage or defect can be readily identified.
