Electric expansion valve

Type ETS 500P, ETS 800P

ETS 500P, ETS 800P are extension to current
electric expansion valves ETS program by
integrate dual ETS 250 or dual ETS 400 in parallel.
They can be used for precise liquid injection in
evaporators for air conditioning and
refrigeration applications with high capacity.

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 valve design uses bi-polar drive providing
very precise flow regulation.

ETS 500P and ETS 800P are compatible with
electronic control solutions from Danfoss and
other manufacturers.

Features • Refrigerants: R134a, R513A, R1234ze,

other refrigerants are on request.

• Rated capacity for R134a:
ETS 500P: 471 TR / 1652 kW
ETS 800P: 640 TR / 2245 kW

• Maximum working pressure: 25 bar / 363 psig.

• Compatible with oil free applications.

• Precise positioning for optimal control
of liquid injection.

• Balanced design.

• Built-in sight glass with moisture indicator.

• Can be operated with flow in both
directions and are solenoid tight.

• Low power consumption.

• Danfoss controller type EKE 1 series can be used
to drive ETS 500P and ETS 800P.

• For manual operation and service of ETS
valves an AST-G service driver is available.
