It works by decelerating box a pinion (Z = 8) led the counter works, if the counter by the valve open or closed position has been adjusted shutoff valve, when the counter with the output shaft to pre-tuned position ( laps), then the cam will be turned 90 o. Oppression micro switch operation, cut off the power valve, motor stops, the trip has been achieved for electrical devices (revolutions) control. In order to control the valve more revolutions, the adjustable cam turn 180 o or 270 o re oppression micro switch operation. Valve type, 江苏兰 valve (certified), the valve is provided by 江苏兰 valve General Equipment Co. Jiangsu Lan valve General Equipment Co., Ltd.
