For a complete list of approved refrigerants and individual code numbers, visit www.products.danfoss.com and search for technical data.

* High pressure refrigerants version (45,2 MWP) only.

** WVFX 10 – WVFX 25 and WVO 10 – WVO 25 with flare connection only; versions with capillary tube or with solder connections are not compatible with R717.

Valve Specifications and Diagrams

The document illustrates two main valve types: WVFX and WVO, along with their technical specifications and a system schematic.

WVFX Valve

Specifications:

Diagram shows the WVFX valve with pressure and temperature indicators.

WVFX Valve (Lower Specification):

Indicates lower pressure specifications for the WVFX valve.

WVO Valve

Specifications:

Diagram shows the WVO valve with pressure and temperature indicators.

WVO Valve (Lower Specification):

Indicates lower pressure specifications for the WVO valve.

System Schematic (WVFX)

A schematic diagram illustrates a system utilizing WVFX valves. It depicts a refrigeration circuit including a compressor, a heat exchanger (coil), a pressure switch (KP), a filter drier (DUB), and the WVFX valve. Arrows indicate the direction of refrigerant flow through these components.

This section is specifically noted as "* only WVFX valves".

Installation/Maintenance Steps

A multi-step diagram illustrates a procedure, likely for valve installation or maintenance:

1. Step 1: Shows two screwdrivers being inserted into a valve component.
2. Step 2: Shows two screwdrivers being rotated in opposite directions, suggesting tightening or loosening.
3. Step 3: Depicts a flow path or connection line, indicating the result or purpose of the previous steps.

The diagram shows a sequence of actions involving tools and a valve.
