Siemens Building Technology 184-112 Restrictor R-407A provided the controller is calibratedThe Siemens 184 112 is a precision engineered 10 SCIM tee restrictor designed for critical pneumatic control calibration. Sold as a 5 pack, these components are essential for maintaining stable air pressure in pneumatic circuits, specifically used to balance signals between controllers and actuators. These restrictors utilize a precise orifice to regulate airflow at 10 standard cubic inches per minute (SCIM), ensuring consistent timing and response
