Valve actuator / actuation -(7)- generator
Generator for valve actuator: 1. The development history of generator controller The automatic control of generator set has experienced relay control. Greatly simplified the control circuit? Reliability has also been improved, to the point of more humanity, there are also some generator manufacturers produce small gasoline engine integrated machine, practical and convenient. 2. Diesel generator […]
Valve actuator / actuation -(6)-Control panel
Control panel of valve actuator: The main purpose of the control panel is to distribute the electrical energy output by the generator to the user’s load or electrical equipment, and it is also used to indicate the operation of the diesel generator and to keep the generator’s voltage stable when the load changes. Generally, voltmeters, […]
Valve actuator / actuation -(5)- advantages
Advantages of valve actuators: Actuator companies can establish a complete, efficient, flexible, and integrated marketing information platform through the application of the CRM system, achieve the following goals, and help companies gain advantages in the fierce market competition: 1. Comprehensive and effective management of customer information resources and market competition information; 2. Master every detail […]
Valve actuator / actuation -(4)-angle stroke valve actuator application
Angle stroke valve actuator application products: 1. Butterfly valve: The baffle of the butterfly valve controls the flow of fluid with the rotation of the shaft. It is composed of valve body, baffle, baffle shaft and shaft seal. Its simple structure, small size, light weight, low cost and large flow capacity are especially suitable for […]
Valve actuator / actuation -(3)-classifications
Double acting valve actuator: The selection of double-acting actuators takes DA series pneumatic actuators as an example. The output torque of the gear-and-pinion actuator is the piston pressure (supplied by the air source pressure) multiplied by the pitch circle radius (arm). And the friction resistance is small and the efficiency is high. The output torque […]
Valve actuator / actuation -(2)-classification and working principle
Classification of valve actuators: (1) According to the driving energy used, the actuator is divided into three types: pneumatic, electric and hydraulic actuators. (2) According to the form of output displacement, the actuator has two types: angle type and linear type. (3) According to the law of action, actuators can be divided into three types: […]
Valve actuator / actuation -(1)-introduction
The valve actuator is an indispensable part of the valve automatic control system. Its function is to accept the control signal sent by the controller, change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. According to their energy form, actuators can […]
Valves’ sealing requirements and daily maintenance
The sealing performance of the valve refers to the ability of each sealing part of the valve to prevent the leakage of the medium. It is the most important technical performance index of the valve. There are three sealing parts of the valve: the contact between the opening and closing parts and the two sealing […]
Stainless steel valve material parameters and specific applications
The following are several stainless steel valve material parameters and specific applications: (1) Angle stroke includes ball valve, butterfly valve, plug valve, etc. (2) Straight stroke includes gate valve, globe valve, angle seat valve, etc. This classification method is divided according to the principle, function and structure. It is the most commonly used international and […]
Classification of valves
Valve classification by function and purpose: (1) Cut-off type: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve, etc. The cut-off valve is also called a closed-circuit valve or a cut-off valve, whose function is to connect or cut off the medium in the pipeline. Check valve, also […]
