Flowserve - Non-Intrusive Multi-Turn Actuator (QXM)

The Non-Intrusive Multi-Turn Actuator (QXM) is an electronic valve actuator engineered for limited, short stroke, light torque rising stem valve applications. Designed for use in sectors such as power, oil and gas, water, and various process industries, it features a non-intrusive electronic design suitable for weatherproof, explosion-proof, and submersible environments. The actuator offers 100% repeatable and redundant absolute encoder position sensing, compatibility with 3-phase, 1-phase, and DC motors, and lower operating costs compared to pneumatic alternatives. It supports advanced process control with high accuracy, meets EN 15714 and IEC 60034 standards, and provides increased reliability through electromagnetic noise protection. The QXM is ideal for modulating, network, and linear control valve services, supporting a wide range of industrial applications.
