Multi-Turn Proportional Electric Actuated Valve

A multi-turn proportional electric actuator valve is used in automation systems to precisely regulate the flow of liquids and gases. This type of valve is controlled by a multi-turn motion directed by an electric motor and responds proportionally to the positioning signals required by the system. It performs with high accuracy in industrial processes, heating and cooling circuits, and liquid distribution systems. Models offered by Unox are developed to be compatible with automation systems.

How Does It Operate and How Is Flow Control Achieved?

In this product group, the valve angle is determined according to electrical signals, providing proportional control over the flow. As the signal changes, the valve opening is adjusted step by step, allowing precise flow regulation. Feedback systems monitor position accuracy, and fail-safe designs enhance system safety. The Unox Multi-Turn Proportional Electric Actuated Valve model delivers this technology within a robust housing.

How Is the Electric Actuator Designed?

The actuator housing is designed to incorporate a three-phase AC motor, a speed adjustment system, torque and stroke control units, as well as a manual switch and gear mechanism. Additionally, an open-position indicator allows real-time monitoring. With a design reaching IP67 protection level according to IEC 34 standards, it ensures safe operation in harsh environmental conditions. Detailed technical documents are available through Unox Online.

What Are the Torque Adjustment and Power Features?

The device features an integrated mechanical torque adjustment mechanism. Although standard settings are applied at the factory, manual adjustments can be made if needed. The power system is supported by a three-phase motor with specifications of 380 VAC / 50 Hz. The insulation class is defined as B according to IEC 34-1, and the duty rating is S2/15 minutes. Additionally, it complies with the NEMA IC40 standard.

Application Areas and Installation Flexibility

These valve systems are especially preferred in refineries, power plants, chemical plants, water treatment facilities, and HVAC systems where process control is critical. Electrical feedback can be continuously monitored and managed from control centers. Additionally, the actuator module can be configured to work with different signal inputs. Synchronized operation is achieved when used alongside products such as the Unox Electric Actuated Flanged Ball Valve.
