Compact and high-power hydraulic control equipment. Energy-saving type and easy to maintain!
This is a high-end model of the HOP series, which has a cumulative shipment record of over 2,000 units to power plants, steel mills, incinerators, industrial furnaces, etc., since its launch 25 years ago. It is a hydraulic actuator that receives instrumentation signals such as 4-20mA and rotates the operating shaft to the corresponding position. The HOP electromagnetic switching valve hydraulic actuator has been enhanced for high speed, high precision, and high torque to meet the needs of the steel industry. It is easier to maintain compared to the injection tube method. Additionally, it is an energy-saving type that minimizes the deterioration of hydraulic oil, resulting in lower running costs. 【Features】 ■ High speed and high precision - Operating speed from fully open to fully closed is 5.5 seconds (50/60Hz) - Hysteresis is 0.75% ■ Easy maintenance - Compared to the conventional injection tube method, it has fewer parts and is easier to maintain - Reduces inventory of replacement parts ■ Self-cleaning action of hydraulic oil in the actuator - The filtration filter (8μ) mounted on the line filter provides self-cleaning action, improving the cleanliness of the hydraulic oil since opening ■ Energy-saving with unloaded circuit - Once positioning is complete, the pump enters an unloaded (no load) state - Since hydraulic pressure is not constantly applied, it suppresses oil temperature rise and cuts unnecessary power consumption *For more details, please refer to the catalog or contact us.

basic information
**Features** <High Speed and High Precision> - Operating speed from fully open to fully closed is 5.5 seconds (50/60Hz) - Hysteresis is 0.75% <Easy Maintenance> - Compared to conventional injection tube methods, the number of parts is reduced, making maintenance simple. - The inventory of replacement parts is also minimal. <Self-Cleaning Action of Operating Oil in the Controller> - The self-cleaning action works with the filtration filter (8μ) mounted in the line filter, increasing the cleanliness of the operating oil from the time of opening. <Energy Saving with Unloading Circuit Adoption> - Once positioning is complete, the pump enters an unloaded (no load) state. - Since hydraulic pressure is not constantly applied, oil temperature rise is minimal, resulting in energy savings with no waste of power. <Simple Switching of Operating Direction with a Switch> - Easily changeable with a switch on the positioner, and the opening signal can also be inverted in the same way. <Three Types of Operating Accuracy Available for Selection at Shipment> - Operating accuracy can be selected from 60°/80°/90°. *For more details, please download the catalog or feel free to contact us.*
