Valve actuator
The actuator, also known as the valve actuator, is mainly used for valve matching in Shanghai Meiyan Yi Pump Valve. It is also called a valve actuator and mainly includes electric valve actuators, pneumatic valve actuators, hydraulic valve actuators, pneumatic hydraulic actuators, etc. It is a device in automation technology tools that receives control information and applies control effects to controlled objects. The actuator is also an instrument that directly changes the manipulated variable in the forward path of the control system, consisting of an actuator and a regulating mechanism. The actuator adjusts the flow rate of the process medium to control the controlled data within the required range of the production process. In a process control system, the actuator consists of two parts: the executing mechanism and the regulating mechanism. The regulating mechanism directly changes the parameters of the production process through the execution of components, making the production process meet the predetermined requirements. The actuator receives control information from the controller and converts it into the output of the driving adjustment mechanism (such as angular displacement or linear displacement output). Valve actuators are connected to the valve body and installed directly on the production site, sometimes under harsh working conditions. Whether the actuator can maintain normal operation directly affects the safety and reliability of the automatic regulation system. The following provides various models, specifications, and pictures of valve actuators for reference only. The dimensions are subject to the drawings provided by our company.

Electric valve actuator
Electric valve actuator is a physical actuator mechanism driven by an electric motor. Electric valve actuator is a driving device that can provide linear or multi turn motion. It uses electric energy to drive and works under the control of current or voltage signals. The main types and driving methods of electric valve actuators include multi turn, straight stroke, angular stroke, etc., and are classified into various functions such as switch type, intelligent type, and adjustable type. The electric valve actuator produced by Shanghai Meiyan Yi Pump Valve is also known as valve electric actuator or valve electric head. The electric valve actuator is mainly used to drive the valve to the fully open or fully closed position or adjust it through electrical energy. The actuator used to control the valve can accurately move the valve to any position. Although most valve actuators are used for opening and closing valves, the design of today's actuators goes far beyond simple switching functions. They include position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules, and PID control modules, all of which can be installed in a compact housing.View details>>

Pneumatic valve actuator
Pneumatic valve actuators are divided into single acting and double acting, straight stroke and angular stroke, diaphragm type and piston type. Single acting pneumatic actuators use springs as the main kinetic energy for valve return, while double acting pneumatic actuators use gas sources to drive valve opening, closing or adjustment. Pneumatic valve actuator is a device that uses pneumatic pressure to drive the opening, closing or regulating of valves, also known as pneumatic valve actuator or pneumatic device, but generally referred to as pneumatic head. The actuator and regulating mechanism of pneumatic valve actuators are a unified whole, and their actuators include diaphragm type, piston type, fork type, and gear rack type. Piston type with long stroke, suitable for situations requiring high thrust; The thin film type has a smaller stroke and can directly drive the valve stem. Fork type pneumatic actuators have the characteristics of high torque, small space, and torque curves that better match the torque curve of valves, and are commonly used in high torque valves. The gear rack pneumatic valve actuator produced by Shanghai Meiyan Yipum Valve has the advantages of simple structure, stable and reliable action, and safety and explosion prevention. It is widely used in production processes with high safety requirements such as power plants, chemical industry, and oil refining.View details>>

Valve turbine actuator
Valve turbine actuator is an important actuator for manual valves and one of the important configuration mechanisms for emergency manual opening and closing valves with manual electric valves. The valve turbine actuator reduces the speed of the gears through the gear ratio, and then reduces the torque required to rotate the handwheel by increasing the diameter of the handwheel, making it easy to open and close large valves manually through the turbine actuator. Due to the frequent rotation of valve actuators, it is easy to cause fatigue and wear of ordinary steel, so the raw materials used for valve execution are mainly cast iron and copper materials. The top of the valve turbine actuator will also be equipped with a pointer to visually see the opening position of the valve. The valve turbine actuator products produced by Shanghai Meiyanyi Pump Valve have a reasonable design structure, durability, and exquisite appearance. New and old users are welcome to choose.View details>>

Valve umbrella gear actuator
The valve umbrella gear actuator is an essential manual actuator for ultra large diameter valves. The valve umbrella gear actuator mainly reduces the torque required to open the valve by adjusting the gear rotation speed based on the ratio of teeth between the large and small umbrella gears. By equipping a large-sized handwheel to accommodate the space required for manual opening and closing of the valve, the ultra large valve can be easily opened and closed manually. The valve umbrella gear actuator produced by Shanghai Meiyan Yi Pump Valve, also known as bevel gear or bevel gear actuator, is a type of gear used for transmission between intersecting axes. It can change the transmission direction and has a single-stage transmission ratio of up to 6 and a maximum of 8. Manual bevel gears are also divided into spur bevel gears and helical bevel gears.
