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. We can manufacture para…

The regulating valve used in low temperature and cryogenic places is called the low temperature regulating valve. So in such a special environment, how do we effectively install the cryogenic control 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 …

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. …

First find the vibration source. For externally induced oscillations, 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 vibration caused by the flow of the internal medium should try to reduce th…

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; while the general shut-off valve is sea…

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. However, how to choose and use fluorine plastic lined valves…

Nowadays, there are many fine and small electric actuators pseudo-explosion-proof/explosion-proof products on the market, which are extremely harmful. Sparks, arcs or dangerous temperatures are generated in places containing flammable and explosive gases and dusts such as coal, petroleum and chemical industries. , The flame of an explosion inside the equipment will spread to the outside of the she…

V-type electric regulating ball valve: It is a rotary ball valve whose core valve seat is made of metal or metal-to-PTFE seal. It combines the best control characteristics of the ball valve and the butterfly valve into one, and can be used as a control valve. It can also be used as a shut-off valve. …
