Description

① EX controls refrigerant freely EX series electrical control valves driven by stepper motor, control refrigerant freely. Fully-sealed stainless steel valve with no external leakage. ② Driven by MVD-01 and sequencer Highly accurate control is achieved by combining EX series with the driver MVD-01 (by MORIKAWA) and using the existing controller, such as sequencer. ③ Driven by EC3-X33, if a sequencer is not available If there is no existing controller, use EMERSON’s superheat controller EC3-X33 together with EX series. (EMERSON’s temperature sensor, pressure sensor, etc. also required.) ④ Contribution to multiple applications Ex Series are classified into 5 types（EX4/EX5/EX6/EX7/EX8）and cover a wide range of capabilities. Available as hot gas defrost, evaporation pressure control valve, and various pressure control valves.
