in many automatic control, because the electric regulating valve quality closes nevertheless, poor flow characteristic, large leakage, action is unreliable and make the automatic control lost high quality regulation, brought great economic losses to the production, and increase the intensity of labor. Because the electric control valve installed on the process piping, direct contact with the operating medium, long-term under high temperature, high pressure, corrosion and friction, etc. The influence of the bad working conditions. So, choose the quality of the regulating valve control function relationship between the system. Therefore, the correct reasonable choice, install the regulator is important. 1, electric regulator should check check and installation after pipe purging. 2, electric control valve installation position should be convenient operation and maintenance, so that people can for maintenance and operation, platform shall be set up when necessary. 3, when the electric control valve installed in the situations of vibration, vibration control measures should be taken into account. 4, electric regulator should be vertical, are installed in horizontal pipe runs, nominal menstruation DN≥ 50 regulating valve, the valve on the pipeline before and after it is better for permanent stents. 5, did not install the electric regulating valve, valve positioner best film head control signal of small gauge installation instructions. 6, electric regulating valve upper and lower part should leave enough space, so as to remove the actuator when maintenance and trims and the lower flange of the valve and plug. 7, electric regulating valve installation position should meet the requirements of process design, and should be near the related indicating instrument at a time, when used in bypass Industrial Valves manual for instrument can observe time; 8, the regulator should be arranged on the ground or platform and facilitate operation and maintenance; 9, the regulator should be vertical installation in horizontal pipe runs are made, under the special circumstances can be installed in horizontal or inclined, but must add support; 10 and regulating valve group ( Including the regulating valve, by-pass valve, cut-off valve and drain valve) Facade installation time, down to the bottom of the regulating valve should be installed in the bypass. Nominal diameter of less than 25 mm regulator, also can be installed above the by-pass; 11, electric regulator is apart from the ground or on the surface of the platform is clear should be not less than 400 mm. For the single and double seat valve valve core, should be set aside at the bottom of the valve body space of the pump valve core; 12, electric regulator membrane on clearance should not be less than 2 mm above. Regulating valve and bypass valve and the layout should be measures open position; 13, should choose the gate valve, cut-off valve should choose cut-off valve, by-pass valve and bypass valve nominal diameter larger than 150 mm, the gate, optional two cut-off valve and control valve arrangement straight in a straight line; 14, the side of the entrance of the regulating valve and control valve upstream of the cut-off valve between the low point of the pipeline should be set drainage valve, drain valve optional gate valve; 15, medium containing solid particles on the pipeline of the regulator and the bypass valve is decorated in the same plane or decorate the bypass valve in the regulator below; 16, low temperature, high temperature regulator set on the pipe should be one of two stents is fixed bracket, the other one is the sliding bracket; 17, electric regulating valve should be installed in the environment temperature is not higher than 60 ℃, no less than. . . 40 ℃, and away from the vibration source; 18, in an area with more regulating valve group, should consider to form consistent, neat, beautiful and easy to operate; 19, electric regulating valve and the diameter of the isolation valve is not at the same time, reducing pipe shall be installed near the adjustment between; 20, pay attention to the process of electric control valve position without special requirements. as a domestic high-end valve manufacturer, always respond to national policy and called for, committed to researching, developing and manufacturing electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valve, the valve to keep traditional valve product sales profits to escort for the innovation research.

In an age when water gate valve is increasingly important, the researchers believe manufacturers should pay close attention to their results.
No, this isn't a wonder product and it won't be likely to change your life but it will give your os & y valve fire protection a kick and bring the extraordinary to the every day. give it a shot at Mech Valve.
