Electric actuator can be classified to three types according to output mode as shown below:1.Angular Travel Electric ActuatorEffective angle of angular travel electric actuator is 0-90°, to control butterfly valve, ball valve, louver valve, ventilation door, plug valve, etc.2.Linear travel Electric Actuator:Linear displacement is output by linear t...

An actuator is a component of a machine that is responsible for moving or controlling a mechanism or system. And a valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. The above-mentioned data shows t...

1. MotorRobust asynchronous three-phase AC motors are mostly used as the driving force, for some applications also single-phase AC or DC motors are used. These motors are specially adapted for valve automation as they provide higher torques from standstill than comparable conventional motors, a necessary requirement to unseat sticky valves. The act...

Actuators are specified for the desired life and reliability for a given set of application service conditions. In addition to the static and dynamic load and response time required for the valve, the actuator must withstand the temperature range, corrosion environment and other conditions of a specific application. Valve actuator applications are ...

Valve positions are operating conditions determined by the position of the disc or rotor in the valve. Some valves are made to be operated in a gradual change between two or more positions. Return valves and non-return valves allow fluid to move in 2 or 1 directions respectively.1.Two-port valvesOperating positions for 2-port valves can be either s...

The modulating type electric butterfly valve which consists of a direct mounted quarter-turn electric actuator and a butterfly valve, also adopts shaft abutment and is connected and matched with a flange. The product is mainly suitable for systems, such as petroleum, chemical engineering, food, medicine, light textile, papermaking, power station, s...

A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required. ...
