Pneumatyczne siłowniki przepustnic D-4300 JOHNSON CONTROLS

These actuators operate pneumatically various damper series in response to a variety of pneumatic input signal
The D-4000 series Pneumatic Piston actuators are multi-purpose positioning devices used primarily in air conditioning systems for operating dampers and mixing boxes in response to the output signals of pneumatic controllers. These actuators are available in two basic sizes, adjustable stroke and different positioning power.
