Jiangsu Lan valve General Equipment Co. IS09001-2008 passed quality system certification. IF, IFM series of intelligent electric valve means are adapted to and supporting a variety of Sloan Valve Company, consisting of the execution unit Valve Company, used in power plants, petroleum, steel, chemicals, pipelines, sewage treatment and other automatic control system lofty Valve Company, both to meet the frequent conditioning control, we have to meet the requirements of intermittent control. Valve alarm function 1) over torque alarm function a, shut TORQUE b, open TORQUE 2) stall alarm function a, close direction stall b, opening direction control stall alarm function * 1) Emergency (ESD) alarm protection 2) loss of signal alarm function * electric device 1) motor overheating protection 2) Control box overheating protection 3) Power failure protection 4) lack of power, out of phase protection 5) Internal system fault protection 6) The current valve position signal Lost protection 7) LOCAL wiring fault alarm * instantaneous reverse direction protection * Local control electric / self-holding contact mode selection function selection function * * * Condition external interlock protection control protection * Two-wire control protection * Torque bypass function * ESD protection beyond the protection * Interrupt setting function * The extra indication contact functions * Remote control setting function * Smart electric device display function * Three-phase power supply phase sequence automatically determine the function Jiangsu Lan valve General equipment - ball valve repair Precautions have a long service life and maintenance-free period will depend on several factors: the normal working conditions, maintain a harmonious temperature / pressure ratio, and reasonable corrosion data valve in the closed state, the body is still there by the internal After the fluid pressure before servicing and relieve line pressure valve in the open position before the repair, before disconnecting the power supply or air service, the actuator must be identified with the bracket from the valve on the downstream pipeline indeed is dismounted pressure to perform Care must be taken when removing decomposition operation decomposition and reassembled to prevent the sealing surface damage of parts, especially the non-metallic parts, remove the bolts on the flange must be symmetrical should use a special tool assembled O-rings, the gradual, evenly tighten the cleaner should ball The rubber parts, plastic parts, metal parts and the working medium (such as gas) are compatible. Working medium for the gas, available gasoline (GB484-89) to clean metal parts. Non-metallic parts with pure water or alcohol to clean the non-metallic parts should be cleaned immediately removed from the cleaning agent, not a long soak after being washed wall needed to be cleaned after volatile cleaning agent (not soaked cleaning agent available silk rub) for assembly Jiangsu Valve Company, but not for a long time on hold, otherwise it will rust, dust contaminated by the new parts in the assembly also need clean assembly should be allowed to have (except for the requirement to use) metal debris, fibers, dust, grease and other impurities and foreign matter contamination, adhere to or remain on the part surface or into the cavity, if a micro-leakage occurred at the packing shall be re-locking stem nut.
