Electric threaded ball valve
Simple introduction
Q 911F electric screw ball valve and butt welded ball valve body casting adopt advanced technology introduced from Taiwan, with reasonable structure and beautiful shape;Valve seat adopts elastic sealing structure, reliable sealing, easy to open and close;The valve stem adopts the down-assembly structure with inverted seal, and the valve stem will not be flushed out when the valve chamber increases pressure abnormally.Two - and three-piece ball valve connection form also butt welding (BW) socket welding (SW), and can be equipped with international standard ISO support platform and locking device.Three-piece ball valve small volume, composed of three parts of the valve shell, through four longer bolts from the two ends of the middle valve body and ball valve.The advantage is that the maintenance dis-assembly does not need to remove pipeline thread, directly remove four bolts, body middle part can be removed.It is suitable for small volume and narrow space of thousand light industrial machinery.With small size, simple form a complete set, large circulation capacity, especially suitable for thousands of media is thick, together with particles, fiber properties of the occasion.Electric screw ball valve is widely used in industrial automatic control system of food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power and other industries.
