c) Thermodynamic steam trap BR642/643
(refer to Fig. 4 page 6)
(detailed description of the control system Operating and installation instructions CONA TD
BR640)
For control the steam trap uses the condensate temperature as well as the available
upstream pressure and back pressure (intermittent operation).
The steam trap vents air automatically during system start-up and operation, but with a time
lag. The steam trap acts as a non-return valve.
d) Ball float steam trap BR628
(refer to Fig. 5 page 6)
(detailed description of the control system Operating and installation instructions CONA SC
BR634)
The steam trap is controlled by a swivel-mounted ball float (pos. 24.16) (level control).
An integrated diaphragm capsule (pos. 24.17) ensures automatic start-up air venting when
cold.
If the amount of inflowing condensate is less than the possible valve output or if there is no
condensate flow, the ball float (pos. 24.16) falls and the valve ball (pos. 24.4) rolls back
onto the valve bore. The valve is now closed.
4.2.2 CONA Connector
System connector for minimization of installation and maintenance space saving and
compact design.
a) System connector BR681
(refer to Fig. 6 page 7)
b) System connector with outside strainer BR682
