Electric Three Piece Ball Valve
Summary
Electric three~piece ball valve is in integration structure, equipped with AOX series electric actuator, input control
signal (4~20mADC or 1~5VDC) and single~phase power to control the operation. It is strong function, small, reliable performance, big flow, light and small, especially suit for viscous medium contains particle or fiber. At present, it widely applies to industrial automatic control system such as food,
pro-environment, light industry, petroleum , paper making, chemical industry and electricity.
Feature
Ball valve in internal thread connecting and butt weld connecting contains one-piece, two-piece and three-piece. The casting of valve body adopts advanced craft from Taiwan, reasonable structure, elegant out shape. The valve seat adopts elastic sealing structure, reliable sealing, easy to open/close. The stem is in back sealing structure installed from the bottom, and the stem will not be rushed out if the valve housing extremely boost pressure. Two~piece, three~piece ball valve have another two connect format BW and SW, are all equipped with ISO frame table and lock device. Set 90° switch position, and lock to avoid mistake operating as requirement.
