Imported pneumatic three piece internal thread ball valve features:
Imported pneumatic three ball screw thread ball valve and welded connections into the integral (one piece), two segment and three segment. Body casting, advanced technology, reasonable structure, beautiful appearance. Seat with elastic sealing structure, reliable sealing, easy to open and close. The stem seal downloading inverted structure, abnormal pressure of the valve chamber, the stem will not be out. Two piece, three piece ball valve connection form another butt welding socket welding, and can support with a platform and locking device. The 90 degree switch positioning mechanism can be provided, and the lock can be prevented according to the need to prevent misoperation.
應用領域：
化工、石化、石油、造紙、采礦、電力、液化氣、食品、制藥、給排水、市政、機械設備配套、電子工業，城建等領域。
Application of imported pneumatic three piece internal thread ball valve:
Chemical, petrochemical, petroleum, paper, mining, electricity, liquefied petroleum gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields.
工作原理：
進口氣動三片式內螺紋球閥當氣動執行器與電路和系統氣源接通后，空氣通過管道A或B管進入A缸（B缸）推動活塞向一端運動，從而帶動旋轉軸和球芯轉動90°。氣動執行器頂部連動可視器，當綠色標志指向“開”字時標志閥門開啟。回信器信號燈綠燈亮時閥門處在開啟位置，而紅燈亮時閥門處在關閉位置。配定位器可調節閥門管道流量。
Imported pneumatic three piece internal thread ball valve working principle:
Imported pneumatic three ball valve when the pneumatic actuator is connected to the circuit and system of gas supply, air enters the cylinder through the A pipeline A or B tube (B cylinder) to push the piston to the end of movement, so as to drive the rotary shaft and the ball core rotates 90 degrees. Pneumatic actuator linkage device when the top visible, green signs pointing to the "open" word mark valve open. When the green light is on, the valve is in the open position and the valve is in the closed position when the red light is on. With positioner can adjust the valve pipe flow.
