Diameters of valve outlets (threaded connections)
The diameters of the valves male threaded connections are standardised as above (see dimension drawing T2)
For units fitted with customer control valves, an intermediate two-part male/female connector is needed between the coil
connector and the valve(s).
This connector is available as an accessory (1, 2 or 4 connectors are required depending on the
configuration (2 or 4-pipe) and the valve type (2-way or 4-way) - consult us).
When a CIA
T valve-based control system is used, the two-part connector is integrated in the control loop.
