Pneumatic ball valves, Pneumatic ball valve) that ball valve with Pneumatic actuator. Also called Pneumatic fast cutting ball valve. Pneumatic ball valve is for use in water, solvent, acid and gas such as working medium, but also suitable for working conditions of the medium.
Pneumatic ball valve product advantages:
1, fluid resistance is small, ball valve is all valve class fluid resistance minimum one kind, even reducing ball valve, the fluid resistance is small;
2, thrust bearing reduce stem friction moment, can make the valve rod long-term operation smooth flexible;
3, seat sealing performance is good, the ptfe etc elastic material made of seal ring, the structure is easy to seal, and ball valve valve sealing ability with the medium pressure increases with the increased;
4, stem seal reliable, because stem only for reverse rotation luck and not do it lifting movement, stem packing seal is not easy to damage, and sealing ability with the medium pressure and increase,
5, because ptfe etc material has good self lubrication, and sphere friction loss is small, so the use of ball valve long life.
6, remove theatrical makeup and costume type of valve stem and valve stem head convex order to prevent the valve rod extrusion, such as fire cause stem seal failure, convex order and valve body, still can form between metal contact, to ensure that the valve stem seal;
7, anti-static function: in the sphere and valve stem, body set up between the spring will switch process is to produce electrostatic derived.
Pneumatic ball valve actuator using new series GT type pneumatic actuators, double acting and single acting (spring reset), gear and rack drive, safe and reliable; The large diameter valve series AW type pneumatic actuators fork type drive, reasonable structure, large output torque, double acting and single acting.
Pneumatic ball valve of the other accessories according to actual needs, carries on the corresponding configuration,
