Electrically operated expansion valves, type ETS
ETS is a series of electrically operated expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications.
The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions.
The ETS needs a current or voltage driver as partner to be operated.
EKC316 from Danfoss and EVD 200/300 from Carel are examples of qualified partners.
The ETS design is being registered. The pending reference number is 200530003728.1.
Features:
* Precise positioning for optimal control of liquid injection.
* ETS 50 and 100 are designed for HFC/HCFC conditions including R410A, providing 45.5 bar (659.9 psig) working
pressure.
* ETS 250 and 400 are designed for HFC/HCFC conditions, providing 34 bar (493 psig) working pressure.
* Balanced design providing bi-flow operation as well as solenoid tight shut-off function in both flow directions at MOPD 33 bar (478.6 psig).
* ETS 50 and 100 have bi-metal connections providing "waterless brazing", improved process and productivity.
* ETS 250 and 400 are both designed with built- in sight glass.
* A built-in sight glass is an option for ETS 50 and 100.
* Cable connectors on request.
* For manual operation and service of ETS
* valves an AST-g service driver is available.
