The invention discloses a ball valve with a soft seal and a hard seal. The ball valve with the soft seal and the hard seal comprises a valve rod 4, a handle 1 and a valve ball 3, the handle 1 is arranged on the top of the valve rod 4, and the bottom of the valve rod 4 is connected with the valve ball 3; the ball valve is a side-mounted ball valve, two annular grooves 7 are formed in a valve body 2, and two spring sets 8 are arranged in the two annular grooves 7 and provided with a hard valve seat 5 and a soft valve seat 6 respectively. For achieving the technical purposes, the ball valve has a better sealing effect, is provided with a monitoring device between a valve rod frame and the valve rod and the telescopic soft valve seat and hard valve seat, has leakage monitoring and overpressure monitoring functions, can be used at places where have the high requirements on the reliability of the valve and solves the problem that a traditional valve is likely to generate leakage in the medium delivery process.
