A multi-turn on-off electric actuator is a control device powered by electricity that provides rotational movement. These actuators are used to open and close valves at specific angles. The “multi-turn” feature is suitable for systems requiring more than 360 degrees of rotation. The “on-off” feature indicates that the actuator operates only in fully open or fully closed positions. In other words, it functions in just two distinct positions rather than intermediate ones. It is generally preferred for the automatic control of large-diameter valves. These types of actuators offer safe, durable, and energy-efficient solutions. Additionally, the manual control mechanism allows for emergency intervention. Models developed by the UNOX brand can be integrated into systems with the advantage of local production.

Where to use?

Multi-turn on-off electric actuators are used across a wide range of industrial applications. They are actively preferred in chemical, petrochemical, energy, and water treatment facilities. They perform reliably, especially in systems where simple open-close commands are sufficient. These actuators can be safely used on valves that require high torque. In addition, they are suitable for water distribution lines, heating and cooling systems, and process automation. They can open and close valves automatically without the need for manual operation. When an electrical signal is sent to the system, the actuator quickly moves the valve to the desired position. They are easy to install, practical to operate, and require very little maintenance.

Technical Structure and Product Features

These actuators operate with a powerful 3-phase motor system. Inside the device, there are a speed regulator, torque adjuster, and stroke control mechanisms. The handwheel can be activated for manual operation when needed. The body is made of durable aluminum and is resistant to harsh conditions. With an IP67 protection rating, the device operates safely against water and dust. It can be easily integrated with many types of valves using the ISO 5211 connection standard. The operating temperature can be safely maintained between -20 °C and +60 °C. The electrical connection is provided via a ½” water-protected inlet. The torque value is selected according to the valve diameter and is offered in variants tailored to specific needs.

Why Should It Be Preferred?

Multi-turn on-off electric actuators offer long service life thanks to their durability and low maintenance requirements. They are an ideal solution for facilities seeking to enhance system safety through easy electrical control. They stand out for their energy efficiency, fast response time, and robust design. Additionally, UNOX multi-turn on-off electric actuator models are available at affordable prices and supported by local production. With easy installation and flexible applications, they can be safely used in any system.
