Key Products/TechnologiesKeyProducts/Technologies
Key product groups include fixed and flexible couplings, fittings, mechanical tees, suction diffusers, and various valves such as Moon Valve, MARS Valve, ABC Valve Proportional Control on/Off, ECO Zone Valve, and KA Automatic Balancing Valve. Particularly, the PICV (Pressure Independent Control Valve) technology is a core capability, comprising an automatic balancing valve, temperature control valve, pressure independent valve, and flow meter. It features microprocessor-based digital control and high flow accuracy of ±5%. Modbus RS485 communication function and dynamic valve for flow feedback enable remote communication with BEMS (Building Energy Monitoring System). The integration of a 360° 6-rotation orifice allows for linear flow control. Non-welding piping technology is also a significant technological capability. Product models include ELT, E, EPro-Series, D-Series, A, B-Series, EZ-Series, KA-Series, KB-Series, W-Series, 720, 736, 730, 740, CS50S, CJ50, CF50, CF20, offering a diverse lineup.Keyproductgroupsincludefixedandflexiblecouplings,fittings,mechanicaltees,suctiondiffusers,andvariousvalvessuchasMoonValve,MARSValve,ABCValveProportionalControlon/Off,ECOZoneValve,andKAAutomaticBalancingValve.Particularly,thePICV(PressureIndependentControlValve)technologyisacorecapability,comprisinganautomaticbalancingvalve,temperaturecontrolvalve,pressureindependentvalve,andflowmeter.Itfeaturesmicroprocessor-baseddigitalcontrolandhighflowaccuracyof±5%.ModbusRS485communicationfunctionanddynamicvalveforflowfeedbackenableremotecommunicationwithBEMS(BuildingEnergyMonitoringSystem).Theintegrationofa360°6-rotationorificeallowsforlinearflowcontrol.Non-weldingpipingtechnologyisalsoasignificanttechnologicalcapability.ProductmodelsincludeELT,E,EPro-Series,D-Series,A,B-Series,EZ-Series,KA-Series,KB-Series,W-Series,720,736,730,740,CS50S,CJ50,CF50,CF20,offeringadiverselineup.
