The FLOWSERVE MARK ONE control valve regulates flow by moving a linear plug within the globe-style valve body. As the actuator receives a control signal, the valve stem moves the plug relative to the seat, adjusting the flow area and controlling the process variable. When combined with a valve positioner, the valve achieves precise positioning, fast response, and consistent performance under changing process conditions.
