Regulator is installed must be from the scene after receiving the regulator, to properly handle the regulator problem. Operators at the different stages of the regulator is installed to adjust the regulator, careless handling regulator may cause device starts delay greatly. Consider the following specific requirements: ( 1) For operating pneumatic control valve of air should be without oil, and dry, especially with the valve positioner. ( 2) Smaller size of the control valve inlet piping to assemble an appropriate filter, in order to filter out the piping system of impurities, avoid damage to the valve. ( 3) installed in the system when the body to avoid pressure, this is of particular importance to valve body separated. ( 4) After the first before starting and breakdown maintenance, the regulator should be loaded on screen before, in order to filter the scale, rust and other debris in pipe line. Whenever possible, piping system to be fitted with a short pipe joint, and before installing the regulator flush piping system. ( 5) As in the environment of plentiful dust in the operation of the regulator, around the stem of a rubber or plastic cover, to polishing surface protection valve stem from damage. ( 6) Be sure to comply with the manufacturers of all position adjustment and auxiliary equipment. For example, in the bypass valve locator position don't forget the bypass switch. ( 7) Can imagine, even if is a good design, also inevitably product for high pressure when the cutting fluid, it is recommended that: if the accumulation of fluid potential energy is very dangerous, exhaust valve should be installed at the each side of the regulating valve and ( Or) Discharge valve. ( 8) For the accumulation of a large number of high pressure material valve, consider installing two exhaust valve and discharge valve is necessary. Accumulated little material between two valves, can gradually release the pressure of the system at the same time, make the pressure between the two discharge or vent valve product set and emissions over and over again. Note that in the process, the regulator must be in the open. ( 9) If the fluid is dangerous gas emissions and vent pipe must be received from a safe place. ( 10) If the regulator is installed later also need to be removed from the system, to close the cut-off valve and add tags. If the regulator is in danger of fluid or pollutants should be combined with the corresponding tag, in order to remove the valve before proper cleaning. ( 11) Be sure to install regulator in accordance with flow direction arrow. If the valve factory to provide the orientation of the arrow is wrong, to report the situation. ( 12) Before installing depends on the specific instructions for each Industrial Valves manufacturer.
