1. The valve may not be used alone as a pipeline ending fitting Always after the valve a blank flange needs to be welded or and connected to the pipeline end When discharging the pipelines the valve has to be turned into a half open position in order to remove all liquid behind the ball Important when the pipelines are discharged in temperatures below 0 C 7 Maintenance The valves do not need extra service at the normal conditions but to guarantee the good working of the valves opening and closing of the valve couple times in a year is highly recommended Change of O rings If needed the upper O ring s of the stem can be replaced without draining the pipelines Follow the instructions when changing the O ring Take care of all special circumstances and when needed contact the manufacturer The instructions can be found from the Internet www vexve fi or directly from the manufacturer Vexve Ball Valve User Manual 7 1 Assembly Disassembly of Ball Valve Manual Gear NOTE The manual gear or actuator may not been removed or dismantled if the valve is pressurized NOTE It is recommended to use the special actuator removal tools 1 Turn the valve to the open position before the gear removal The valve opens when turned the gear handle to the counter wise direction 2 Turn the hand wheel slightly closed to the point when the wheel turns easily 3 Before the gear removal remove the position indicator plate s bolts2.
