HL2X series modulating valves are the combinations of VA-500 and VA-1000 actuators and DN15-DN50 modulating valve bodies that are individually developed, designed and produced by HaiLin Corporation. They have been extensively used in the air conditioning, refrigeration, heating and building automatic control systems, which can accurately modulate the flux of the medium and can reach the targets to control the temperature, humidity and pressure of the systems.
