• Valve mobile phone control based on IoT control

    At present, the world is close to 7.53 billion people. A recent study found that, on average, 33% of the world’s population suffers from a shortage of water resources in some form or other form. By 2030, that number is likely to rise to 50%, a clear highlight of the alarming rate at which water scarcity is widening. Interestingly, about 70% of the world’s water intake is used for irrigation, which is exactly where most of the waste water occurs….

  • The selection of valve electric actuator should be based on what?

    The QOTO valve electric actuator is a device that operates the valve and connects it to the valve. The device is electrically driven and its motion can be controlled by stroke, torque or axial thrust. The performance and use of valve electrical equipment depends on the type of valve, the operating specification of the equipment and the position of the valve in the pipe or equipment. Therefore, it is important to properly select the valve installation equipment and consider how…

  • How to select electric Actuator for gate valve?

    Electric gate Valve The correct choice of electric actuator is a basis to follow, the following points can be referred to: 1. Operating torque: Operating torque is the most important parameter to select the gate valve electric device, the output torque of the electric actuator should be 1.2~1.5 times the maximum torque of the gate valve operation. 2. The main structure of the operation Thrust Gate valve electric device has two kinds: one is not to configure the thrust disk,…

  • What is a valve actuator?

    At present, the common implementing agencies such as: pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage. Hydraulic movement mainly refers to the unified setting of an oil station, and then the oil is distributed to each hydraulic actuator, mainly used in the factory more dense valve area. Gas-liquid linkage is often used in dispersed areas and is not easy to lay cables, and the medium in the pipeline is compressed gas (such as the west-to-East gas pipeline), using the compressed gas…

  • Principles of Switching and Adjustable Electric Valve Actuators

    Electric actuator in the control mode, there are two kinds of switching electric actuator and adjustable electric actuator, many customers do not understand the switch type and adjustment type of different, the main difference is that the valve switch control function is different. 1, switch type electric actuator switch type electric actuator is also known as open-loop control electric actuator, this actuator in the execution of valve operation only open, off two actions, that is, can only make the valve…

  • Teach you to understand the electric actuator wiring diagram

    First of all, to figure out the meaning of the various logos, and then understand the connection method, and then learn to see the different styles of the map. Electric valve actuators can be divided into AC (AC110V, AC220V, AC380V) and DC (DC24V, DC12V) according to the power supply voltage. They are divided into active switch type, passive switch type, potentiometer type and regulation type according to the control mode. Through the different wiring diagrams below: 1, active switch type,…
