Check valve

Type CCV

Magnetic type

Magnetic type check valves are designed for installation in commercial refrigerating systems and in residential or industrial air conditioning plants. They are used to control the unidirectional €ow of refrigerant to prevent back€ow; the magnetic actuator guarantees a high reliability standard.

Features:

• Ensure the correct €ow direction

• Hermetic construction design

• Magnetic closure element for high reliability standard

• Low pressure drop during operation

• 100% copper connections for easier soldering

• Can be installed in any position and direction in the system

• Soft sealing by NBR is less sensitive to dirt in system

<![if ! IE]> <![endif]>Danfoss 32B18		1	When the di‚erential pressure is less than Min.
			opening pressure or has reverese pressure, CCV is
			closed. The diaphragm is attracted by magnet and
			stay in the left of the bracket.

<![if ! IE]> <![endif]>Danfoss 32B19		1 When the refrigerant €ows through the valve and
		the di‚erential pressure is more than Min. opening
		pressure, the diaphragm will move to the right of
		bracket, then the valve will open.

Application

Typical applications for CCV valves are:

•Cold room

•Heat pump

•Chillers

•VRF
