SPV03 series flow balancing modulating valve is combined flow sensor and modulating control valve. The sizes are from DN20 to DN50. Users can preset the flow limit under maximum Kv rating according to terminal design request even before water running. The valve will be positioned to its optimum operating position according to the signal from the actuator until the preset flow limit is reached and then the preset flow rate limit will be maintained.
