) at a differential
pressure of 100 kPa (1bar)
The SSA955 can operate without adapter radiator valves of other manufacture provided
they have a connecting thread M30x1.5 mm and meet the following requirements:

The following makes satisfy these requirements and can be used with the SSA955:
· Honeywell MNG
· Cazzaniga
· Heimeier
· TA
· Finimetall
· Oventrop M30x1.5 (from 2001)
· Junkers
Other combinations on request.
To ensure optimum control performance, the valve’s volumetric flow should not be
preadjusted.
If preadjustments are required, refer to the relevant technical documentation on the
valves for detailed information. The SSA955 supports valves with a stroke of > 0.5 mm
(refer to paragraph “Calibration”).
