Accessories for control valves

We offer a comprehensive range of accessories for Baelz control valves. This allows the Baelz control valves to be used in even more applications.


baelz 206r

The pressure measuring and control element baelz 206r is generally used with baelz 192 as a pressure-reducing valve. The set point can be selected by adjusting the tension in the springs using a handwheel.

  24 VAC/DC or VUC (Ex-version)

baelz 6250

The baelz 6250 orifice plate protects the valve against damage caused by an excessive pressure drop and has a noise-damping effect. The orifice plate is connected downstream from the valve and absorbs most of the pressure drop. Thus, the cheap orifice plate is „sacrificed“ to prevent damage to the expensive valve.
