Pneumatic eccentric half ball valve with handwheel introduction
Pneumatic eccentric half ball valve with handwheel belongs to the Angle stroke valve, which is composed of the Angle stroke piston pneumatic actuator and the eccentric ball valve. Pneumatic eccentric half ball valve can be equipped with the valve positioner input control signal (4-20madc or 1-5vdc) air source to control operation.Pneumatic eccentric half ball valve can also be equipped with stroke limit switch, solenoid valve, pressure reducing valve and air source of 0.4-0.7mpa to realize switching operation, and send out two pairs of passive contact signals indicating the switch of the valve.Pneumatic eccentric half ball valve is a kind of Angle stroke control valve which controls the fluid by rotating part of the ball valve plate around the eccentric axis.The rotary center of the valve core is not concentric with the rotating shaft, which can reduce wear and prolong the service life.Secondly, there are large flow, adjustable range and other characteristics.Pneumatic eccentric half ball valve is widely used in petroleum, chemical, electric power, metallurgy, steel, paper, medicine, food, textile, light industry and other industries.
