Siemens Building Technology 331-2976 Actuator 319848-301 Precise Control: The clearly graduatedThe Siemens 331 2976 is a heavy duty No. 4 pneumatic damper actuator engineered for precise control in commercial HVACR systems. Specifically designed for applications requiring a 4 inch stroke and a 5 10 psi spring range, this unit provides the necessary force for the gradual or positive actuation of damper linkages. Its rugged steel housing is finished with a cathodic epoxy electrocoat to resist corrosion, making it a reliable choice for air
