    Tips: Pneumatic valve actuator vs. electric valve actuator

    Pneumatic valve actuator advantages

    • The load is large, which can adapt to the application of high torque output.
    • Quick action and quick response.
    • Good adaptability to working environment, especially in harsh working environments such as flammable, explosive, dusty, strong magnetism, radiation and vibration, it is superior to hydraulic, electronic and electrical control.
    • The motor is easily damaged when the stroke is blocked or the valve stem is tied.

    Electric valve actuator advantages

    • Compact structure and small size. Compared with pneumatic actuators, electric actuators are relatively simple in structure. A basic electronic system includes actuators, three-position DPDT switches, fuses and some wires, which are easy to assemble.
    • The drive source of the electric actuator is very flexible. Generally, the on-board power supply can meet the needs, while the pneumatic actuator needs an air source and a compression drive device.
    • Electric actuators have no danger of "air leakage" and are highly reliable, while the compressibility of air makes pneumatic actuators slightly less stable.
    • There is no need to install and maintain various pneumatic pipelines.
    • The load can be maintained without power, while the pneumatic actuator requires a continuous pressure supply.
    • The electric actuator is quieter because no additional pressure device is required. Usually, if the pneumatic actuator is under heavy load, a silencer should be installed.
