Q310 series O-type ball valve adopts straight-through full-diameter structure design, which has the characteristics of large flow capacity, small pressure loss, fast action time and long service life. The valve stem is designed to prevent flying out of the structure, and the valve has anti-static and fire prevention functions.

The series O type ball valve has floating ball valve and fixed ball valve two kinds of structure. Floating ball valve is generally suitable for medium and low pressure, nominal diameter less than DN200 valve; fixed ball valve is generally suitable for medium and high pressure, nominal diameter greater than or equal to DN200 valve.

The series of O type ball valve seat material can be divided into soft seal O type ball valve and hard seal O type ball valve. Soft seal O-type ball valve is generally suitable for medium and low pressure, the temperature is less than 220 ℃, the medium does not contain particles; hard seal O-type ball valve is generally suitable for medium containing particles, fibers and high temperature and high pressure and other harsh conditions.
