Energy-saving yet high power! It can suppress the degradation of hydraulic oil and is easy to maintain. Active in various plants and more.
The "HOP4" is an electric hydraulic servo actuator that controls hydraulic pressure by receiving 4-20mA instrumentation signals from external sources and operates a cylinder using an electromagnetic valve control method. It is suitable for opening degree control of various valves, dampers, and butterfly valves, and is actively used in airflow control, pressure control, and other applications in various plants. When not in operation, the power-down function minimizes power consumption, and the reduced oil temperature rise helps suppress the deterioration of hydraulic oil, contributing to the longevity of the oil. 【Features】 ■ High cost performance ■ Compact design, saving installation space ■ Ensures high torque ■ Highly reliable design ■ Easy one-touch switching of operating direction *For more details, please refer to the documentation.
