The working principle of electric three type pneumatic ball valve

three type pneumatic ball valve (electric Internal thread connect pneumatic ball valve) And butt welding ball pneumatic valve is divided into integral ( A chip) And two stages and three. Pneumatic valve casting adopt Taiwan to introduce advanced technology, reasonable structure, beautiful appearance. Pneumatic valve seat adopts the elastic sealing structure, reliable sealing, easy opening and closing. Pneumatic valve stem has inverted sealing bottoms type structure, pneumatic valve cavity when the abnormal pressure, pneumatic valve stem will not be rushed out. 2 chip, chip pneumatic ball valve connection form otherwise butt welding ( BW) Socket welding ( SW) And all can with the international standard ISO support platform and locking device. Can be set up ° switch positioning mechanism, according to the need to lock to prevent wrong operation, drive mode: manual, electric, pneumatic. Three type electric pneumatic valve fluid resistance small, are all pneumatic valve fluid resistance in the smallest one, with ACV, ACV or DCV listed listed power supply voltage, accept ( - mA、- MA or - 伏直流电) Current or voltage signal, can control operation, to Angle the itinerary of the output torque rotating sphere ~ °, opening and closing action or adjust the action will be finished. All electronic electric actuators, mining electromechanical integration structure, has a built-in servo operation and opening position feedback signal, position indicator, manual operation, and other functions, functional, reliable performance, simple connection, through the input current or voltage signal, to change the spool rotation Angle ( - ° at any Angle) And realize the proportional control action. Ball core channel level off is smooth, not easy sedimentary medium, can be in-line ball. Simple structure, light weight, good sealing performance. Especially suitable for the requirement of zero leakage rate.
