The valve open or closes by turning the ball. Clockwise turning to 90results in valve open.6.1 The manually operated valve is opened when the handle and the position mark on stem end are parallel to pipeline. When that is perpendicular to the pipeline, the valve is closed.6.2 For motor/pneumatic operated valves, valve open/close is indicated by the positioner on the electric/pneumatic actuator.7 Storage, maintenance, installation and service7.1 The valve should be stored in dry room with good ventilation. Valve ends should be covered.7.2 For valve stored for a long period of time, regular checkup is required to ensure that the valves are in good conditions. Foreign particles should be removed and special care should be taken to keep the valve seat sealing surface clean and prevent any damage of sealing surface.7.3 Check the conformance of valve identification to the service requirements prior to installation.7.4 Check the cleanness of the valve cavity and sealing surface and sealing surface and wipe off any dirt with white cloth prior to installation.7.5 Before installation, the tightness of packing should be checked to ensure that sealing is secured without affecting the turning of stem.7.6 The valve shall be in full open position when conducting system or pip line pressure test after the valve installation.7.7 Ball valve shall be in full open or full close position while in service. partial opening for controlling the flow is not allowed.7.8 Manually operated valve should be operated by using the handle. Use of lowers or other tools is not allowed.7.9 Valve in service should be examined at prescribed intervals to see whether the wear of sealing surface or stem occurs and the gasket or packing fails. Repair or replacement shall be carried out timely if necessary.7.10 “Electric valve actuator instruction manual” and “Pneumatic valve actuator instruction manual” should be referred with regard to the storage, maintenance, installation and service for motor-operated valve and pneumatic-operated valve respectively.8 Possible troubles, causes and solutions see table Possible trouble Causes Solution Leakage throughPacking 1.Packing not sufficiently pressed2.packing failure1.Tighten the nut to press packing evenly2.Replace packingLeakage throughSealing surface 1.Dirt attached to sealing surface2.Sealing surface damaged1.Clean off the dirt2.repair the sealing surfaceLeakage throughbody and bonnetconnection1.Bolti
