Frequency conversion speed modulated valve

• Features and performance
• 1.BSD Frequency conversion speed moudlated valve with the function of speed modulated,checking and shutting -off.
• 2.The valve with the continuous action that’s slow-open,fast-open,or fast close,slow close",which significantly precent the flow come back from the pump outlet and the water hammer.
• 3.Operated by the worm gear box,the valve can be opened to any angle by the auto-lock device,and solving the problem of oil leakage and hammer malfunction that the traditional electro-hydraulic valve happened frequently.
• 4.Loading the flow velocity sensor in the pipeline,parallel connected with the valve,when the pipeline failure happened,the valve will be closed automatically by the close signal when the flow speed become faster.
• 5.Vale with adjustable seal part can stand 0.2million times operating.
• 6.Special metal seal structure,the seal part will not be deformed at high or low temperature.
• 7.Triple eccentric design facilitates an immediate opening or closing with least friction.
• 8.The position device along the stem eliminates the leaking and bottom seal faces resulted from the up and down axial movement of the disc,which makes it possible to install the actuator in any direction (For the valve size more than 500mm,we suggest horizontal installation).
•  
• Structure & features
• Conversion control fast-slow close Random adjustment without water hammer
•  
•  
• User can find the better product by compare with the above two type butterfly valves
• 1.The price for traditional electro-hydraulic hammer type butterfly valve is expensive,and the control structure is complex,and the oil leakage and the hammer failure happened frequentlyl,has a big problem in the system security and environment pollution.However,the BSD Frequency Conversion Speed Modulated Valve with simple structure and easier operation,using the electro operation instead of the hydraulic operation,the using system become more safety and the working environment become more clean.
• 2.The traditional electro-hydraulic hammer type butterfly valve using the heavy and huge valve hammer to close the valve,so the installing volume capacity wlii be limited.The BSD Frequency Conversion Speed Modulated Valve with the features of new considered design,small volume,easy installation,energy and money saving.
• 3.BSD Frequency Conversion Speed Modulated Valve operated by the worm gear box.with good auto-lock function,so the valve can open to any angle but the traditional electro-hydraulic hammer type butterfly vlave can’t owing to the pressure lose or oil leakage.
• 4.BSD Frquency Conversion Speed Modulated Vlave can adjust the ‘fast closing’,‘slow closing’,‘open angle’,‘Open time’freely,but the traditional electro-hydraulic hammer type butterfly valve can’t.
• BSD Frequency Conversion Speed Modulated Valve(see figure 2)can be used for the pump outlet pipe system;the medium can be water,seawater,and oil.This valve can replace the traditional electro-hydraulic hammer type butterfly valve working ad the close-up valve to prevent and reduce the back flow the pipe system,(see figure1)realizing the function of ’fast closing’and ’slow closing’.When the pipe failure happened,tha valve can be fast closed to prevent the water leakage and oil leakage happened.BSD Frequency Conversion Speed Modulated Valve can be divided into three part,that’s the electric actuated device.valve body,and control part.It can be worked with the pump directly ,and work accord to the user’s needs as well.To prevent the back flow or flow hammer happened and to keep the pipe system more safety.
•  
• BSD Frquency Conversion Speed Modulated Valve can fulfill the function circle of ‘slow open’,‘fast open’,‘slow open’(see figure 3),and ‘slow close’,‘fast close’,‘slow close’(see figure 4)etc.Making time and open angle adjustment according to the different conditions and user’s needs.
