Neles RE Series Segment Valve
Brand: ValmetMetso's Neles RE Series Control Valves are economical, high performance valves in a quarterturn design.
They are offered with a variety of trim options from standard and low Cv trims for general applications to noise/cavitation Q-Trim for reducing aerodynamic noise and preventing cavitation.
Standard units are equipped with either diaphragm or cylinder actuators and ND9000 intelligent valve controllers for precise control, reliability and performance monitoring on-line.
