Recently, ( Electric drive disc valve) Factory has will control institutions opening and closing of the trip. To prevent power on is the direction to make wrong, the user after the first switched on, the first open to half open position manually. Pneumatic valve regulating the whole flow thread ball valve (ball valve testing and debugging and common troubleshooting methods: description: a, install, test and adjustment: 1, the product manual, pneumatic, hydraulic, electric parts are strict debugging before they go out, the user when the re-inspection sealing performance, import and export shall be uniformly fixed on both sides, close the disc valve, pressure on suction side, in the export side to observe any leak phenomenon, before the trial, the strength in the pipeline should open the disc plate, seal and prevent air compressor valve, spring safety valve, micro and safety valve, stainless steel relief valve, steam safety valve, power station valve. 2, our products are through the strict inspection before they go out, and the experiment, but there are also individual products in transit automatic screw dislocation, to readjust, pneumatic, hydraulic, etc. , please read the form a complete set of drive operation instruction. 3, ( Electric drive disc valve) Factory has will control institutions opening and closing of the trip. To prevent electricity is the direction to make wrong, the user after the first switched on, the first to open the manual to half open position, in the direction of electric switch check the dial with the valve closed in the same direction. Second, the common faults and eliminate method 1, pneumatic ball valve before installation way to confirm our products performance and whether the medium flow arrow is consistent with the movement conditions, and the valve cavity clean, do not allow foreign body with impurities in the sealing ring and the bat, before cleaning must not be allowed to shut down the bat, so as not to damage the sealing ring. 2, disc plate installation supporting disc valve special flange, flange recommended HGJ54 - namely The type 91 socket welding steel flange. 3, installed in the pipeline position, the best location for the vertical loading, but can't flip. 4, use the traffic needs to adjust, a worm gear box control. 5, on and off a lot of ball Industrial Valves, in 2 months time, open the worm gear case cover, check whether the butter is normal, should keep the right amount of butter. 6, check the connection parts require compaction, namely to ensure that the packing bees, guaranteeing stem flexible rotation. 7, metal sealed ball Industrial Valves is different from the product is not suitable for installation in the end of the pipe, pneumatic ball valve must be installed in the end of the pipe, take equipped with export hair, prevent the backlog of sealing ring, too.
This is an global standard which acts as a form of promise that Shenzhen Mech Valve Trading Co., Ltd. manufatures according to the finest quality standards.
