1.Pneumatic control ball valve Product overview

Pneumatic control ball valve is regulated by a single action or double acting pneumatic actuator and flange type V type ball valve, and is equipped with electric - valve positioner YT locator and can be equipped with Siemens smart positioners. By controlling the signal of 4-20mA positioner to achieve proportional control valve. Ball valve spool design with a V-notch special shape, with a precise closure properties and control functions for a variety of control applications, compact structure, small size and so on.
Because it is no gap between the rotary valve and seat, and therefore have a lot of shear force and self-cleaning properties, so Pneumatic control ball valve suitable for containing fibrous or suspension of tiny solid particles and solid granular control. It can be widely used in petroleum, chemical, paper, chemical, electric power, metallurgy, pharmaceutical, environmental protection and other industrial sectors of the automatic control system.
