Overview
This kind of product is assembled by O-type floating ball valve or fixed ball valve body part gas and fine piston type single and double acting actuator. It has the characteristics of small volume, circulation capacity, light weight, large output torque and stable and reliable action. Due to the shearing function between the core and the valve seat, it is suitable for the control of fluids such as suspended solids, high viscosity, low pulp and pulverized coal. It is also suitable for the control of various gases and fluids.
