Electric expansion valve Type ETS 8M

ETS 8M is a stepper motor driven electric expansion valve with a high level of reliability, and it provides a precise solution for expansion and ow control in a wide range of refrigeration and air conditioning system. The valve comes with two ow curve options, a linear and a S-shaped characteristic.

ETS 8M can be applied for applications i.e. Modular Chiller and Low Ambient Temp Heat Pump in single/bi-ow operations.

Valve operation is by means of a uni-polar motor, and as such it is compatible with a number of electronic controllers from Danfoss or third-party vendors.

Features:

• High MOPD to comply with compressor operating envelope

• Low internal leakage

• Long lifetime and durability

• Optimized valve ow characteristic

• Stable ow control at low opening degree

• Dedicated ow control curve for heat pump

• Compatible with existing valve drivers

• Bi-ow, with good performance in both ow directions

• Flexible installation: vertical orientation ±90°C

• Coil enclosure up to IP67

• In accordance with

◦ JB/T 10212 ◦ RoHS (China and EU) ◦ REACH ◦ PED

Portfolio overview

ETS 8M is a system product whose function is controlled through a Danfoss electronic controller or a third-party vendor electronic controller that is compatible with the ETS 8M as to control functionality and connections.

The electronic controller requires precise temperature input from a temperature sensor (refrigerant temperature) and precise pressure inputs (evaporator pressure) from a pressure transmitter.

Product specication

Design

The ETS 8M Electric expansion valves open and close to regulate refrigerant ow by means of a screw whose rotating motion is transformed into linear motion. This occurs by the rotation of a magnet needle valve assembly which moves when electrical signals are applied to the surrounding coil. Within the coil structure, there are dierent winding congurations, and the polarities are changed by the electrical signals applied.

By application of the appropriate combination of signals, in the form of pulses, the coil forces the rotor of the valve to move in a stepwise fashion. Application of multiple pulses will make the valve mechanism move through a series of steps in the chosen direction, in order to set the valve with the required opening degree.

The reverse ow capacity of Orice 4.0 and 4.5 with 3/8" connection is slightly lower than the 5/8" connection, please contact Danfoss for more details.

Valve selection based on capacity calculation

As for extended capacity calculations and valve selection based on capacities and refrigerants, please refer to Coolselector

®

Rated and extended capacities are calculated with Coolselector®2 calculation engine to ARI standards with the ASEREP equations based on laboratory measurements of selected valves.

Electrical connection

Electrical connection is via a xed cable in a number of lengths from the coil to the controller. Cables up to 6 m length are available with a JST XHP-5 / JST XHP-6 connector. See ETS 8M ordering for details.

Electrical and motor specications

Valve operation is by means of a Uni-polar motor, designed as a separate coil that clicks onto the valve body.

Stepper motor switch sequence

The stepper motor opens and closes as outlined in the table, opening moving to the right of the table, closing moving the opposite direction.

Ordering

Parts program

ETS 8M is a parts program consisting of a valve body and a separate Uni-polar motor coil (ETS 8M coil). Each component is purchased separately. See ordering details below.

Table 8: ETS 8M program

Besides using the ETS 8M coil as spare part, ETS 8M valve is hermetic and unserviceable, therefore is no other spare parts.
