Motorized Three-way Valve
The electric three-way valve is a precision fluid control component integrating electric actuator and three-port valve body, designed for medium diversion, confluence, or flow direction switching in automatic control systems . Driven by gear transmission mechanisms (AC/DC motor), it adjusts the valve core position to regulate fluid distribution or redirect flow paths, eliminating manual operation delays. Two core spool designs meet diverse needs: L-type spool for on-off switching of single flow direction (e.g., medium diversion between two pipelines) and T-type spool for proportional mixing/confluence of two media or full-path shutoff . It is widely used in HVAC, industrial processes, and medical systems requiring automated fluid control.
Description
Nominal Diameter: DN15~DN300 (NPS 1/2"~12")
Working Pressure: PN10~PN16 MPa (145~232 psi)
Temperature Range: -29°C~300°C (soft seal ≤280°C; hard seal ≤450°C)
Control Precision: Flow adjustment error ≤±2%; response time ≤0.5s
Actuator Voltage: AC220V/380V; DC24V (optional with feedback signal output)
Certifications: CE; EAC (CU-TR 010/032 for Eurasian market) ; ISO 10993 (medical grade)
Align the valve body's flow direction marking with the pipeline system (L-type spool avoids reverse installation) .
Use flange connection for DN≥50 (gasket: PTFE for chemical media) or thread connection for DN<50 (PTFE tape sealing).
Reserve 200mm clearance around the actuator for wiring and maintenance; avoid direct sunlight/rain.
Cleaning: For industrial use, flush with neutral detergent quarterly to remove medium residues (avoid scouring pads on PTFE seals).
Inspection: Check sealing rings annually-replace if hardness change exceeds ±5 Shore A .
Calibration: Verify actuator feedback signal accuracy every 6 months (match with valve opening degree).
