What are the advantages of the double disc gate valve?
The double gate valve is suitable for the pipeline with water and sewage as the medium as a closed circuit device, and cannot be used for flow regulation or discharge. It is widely used in petroleum, chemical, pharmaceutical, electric power and other industries. It is used to open and close the steam, water, oil and other medium pipelines with a nominal pressure of ≤1.0MPa.… -
Can't be careless when installing a low-temperature control valve
The regulating valve used in low temperature and cryogenic places is called the low temperature regulating valve. The electric low-temperature control valve checks whether the parts of the whole machine are damaged or loose. For the use of media that are harmful to human health, strength, sealing, leakage … -
What is the relationship between the diameter of the electric control valve and the flow rate
The flow and velocity of the electric regulating valve mainly depend on the diameter of the electric regulating valve. It is also related to the resistance of the electric regulating valve to the medium. At the same time, it has a certain connection with the pressure, temperature and concentration of the medium of the electric regulating valve. … -
What are the factors that affect the accuracy of electric valve electric actuators?
the control valve should be kept away from the vibration source; eliminate or weaken the vibration intensity of the vibration source; and use methods such as increasing the fulcrum to weaken the vibration of the control valve when deemed appropriate.… -
The bellows globe valve is compared with the ordinary globe valve. What are th e advantages of the bellows globe valve?
The bellows cut-off valve uses a sealed bellows that can be stretched and compressed to replace the packing seal, which can effectively prevent external leakage caused by packing loss. It is generally used for the transmission of highly permeable media, such as valves on hydrogen systems, as long as the bellows is not damaged, there is generally no leakage.… -
The requirements of the applicable environment of the electric fluorine-lined valve are complied with
Electric fluorine plastic lined anticorrosive valves have been widely used in petroleum, chemical, pharmaceutical, metallurgy, electric power and other industries that are exposed to acid and alkali and other strong corrosive media.… -
What is a flameproof electric actuator?
