light industry “o” ball valve is a right angle rotary cut-off valve. its few occasions also use the regulating valve. it is used with pneumatic actuators or electric actuators for remote control, manual control with handle or worm gear. its structure adopts two-way sealing design of movable seal seat. the valve core has a large shear force and self-cleaning function when there is no clearance between the two-way sealing seats, and is particularly suitable for controlling fibers and suspensions and viscous media with minute solid particles, so this product is widely used in papermaking, in the petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial sectors of the automatic control system.
