twenty 2021-08 What should be paid attention to when installing the electric ball valve? At present, the quality problem of the electric ball valve of Shanghai Yonglong Valve Factory has become a topic of discussion. The electric ball valve with powerful performance is not easy to be damaged due to the blockage of the gas buffer during operation, so it can adjust the flow to a large extent without the need to adopt -
eleven 2021-08 What should be paid attention to when installing the electric ball valve? The electric ball valve is an intelligent regulating device connected by the relevant actuator and the valve. This device often needs electricity to drive the valve, thus playing a corresponding regulating role in the pipeline medium. Generally speaking, when purchasing electric ball valves, we should not only pay attention to -
twenty-six 2021-06 How to correctly select the electric valve_Yonglong electric shut-off valve There are many kinds of electric valves, including electric ball valve, electric butterfly valve, electric gate valve, electric shut-off valve, electric stop valve, electric diaphragm valve, electric plug valve, electric emergency shut-off valve, etc. The structure and material of valve body are the main parameters for selection -
nineteen 2020-09 Electric shut-off valve - what do the colored wires of the actuator represent Electric shut-off valve, electric emergency shut-off valve, electric ball valve and electric butterfly valve actuators use motors as the driving force, and the actuators have multiple wiring ports built in. Usually, wires of different colors are used to distinguish internal wiring, so as to avoid actuator inaction caused by wrong connection -
eighteen 2020-08 Yonglong explains the purpose of correctly selecting the type of electric valve In short, electric valve is a valve driven and controlled by electric actuator with power supply, so as to open and close the valve. It can be divided into upper and lower parts. The upper part is an electric actuator, and the lower part is a valve, which can also be called an electric shut-off valve -
twenty-six 2020-04 Electro hydraulic actuator - electro-hydraulic butterfly valve - electro-hydraulic linkage butterfly valve The electro-hydraulic actuator integrates the motor, oil pump and electro-hydraulic servo valve, and can work as long as the power supply and control signal are connected. It is ideal for remote areas that cannot provide air supply pressure but need to accurately control the valve core position -
05 2019-09 The purpose difference between electric ball valve and solenoid valve Both electric ball valve and solenoid valve are operated by power control switch, and they have different advantages and disadvantages. The electric ball valve is slow to open and close, has long service life, and the solenoid valve is fast to open and close. The coil is prone to heat and damage, and the cleanliness of the medium is required -
thirty-one 2019-08 Difference between regulating valve and on-off valve electric actuator When selecting the type of electric ball valve, in addition to the matching with the valve and other components, the control mode of the electric actuator of the valve should also be considered. There are two common types of electric actuators, namely, the on-off electric actuator and the adjustable electric actuator, which do not have the function of valve on-off control -
twenty-four 2019-04 Debugging method and wiring of German EMG electric valve German EMG is an earlier professional manufacturer of electric actuators in Germany and Europe. EMG electric actuators are used in various fields, including power, water plants, sewage treatment plants, petrochemical, metallurgy, paper making, shipbuilding, food, municipal, nuclear power, etc -
twenty-two 2019-04 Common faults of angle travel electric actuator _ Shanghai electric ball valve manufacturer Angular travel electric actuators are widely used in the automatic control field of electric power, metallurgy, petroleum, chemical and other industrial sectors. The products include electric ball valves, electric shut-off valves, electric butterfly valves, electric gate valves, electric stop valves, and electric control valves
