Refrigerant Circuit Connections With Valve For Switches
Switching pressures, removing and installing switches as well as switch arrangement and version. Refer to REFRIGERANT CIRCUIT (vehicle-specific repair information).
- Different threads for switch on high pressure and low pressure sides.
- Only valves and seals that are resistant to refrigerant R1234yf and refrigerant oil must be installed.
A - Connection (soldered in)
B - Seal
C - Valve (with Seal)
To remove and install the valve insert -C- when the refrigerant circuit is discharged, use, for example, an adapter from the Refrigerant Sockets :T10364 (Tightening specification. Refer to QUICK-RELEASE COUPLING CONNECTIONS ON REFRIGERANT CIRCUIT ).
There are different versions of these valves and therefore there are different tightening specifications. Valve insert -C- with a VG5 (5.2 x 0.7 mm, tire valve) thread has a tightening specification of 0.4 Nm ± 0.1 Nm; a valve insert with a M6 x 0.75 mm thread has a tightening specification of 0.9 Nm ± 0.1 Nm, and a valve insert with a M8 x 1.0 mm thread has a tightening specification of 2.0 Nm ± 0.2 Nm.
