The electric actuator is equipped with a servo system, and no servo amplifier is required. It can be controlled with input signals and power supply. The connection tube is simple, and the regulating mechanism adopts top guidance. It is suitable for occasions with strict requirements on leakage, low pressure difference before and after the valve, and certain viscosity and fiber-containing media.
