Siemens Combustion LDU11.523A17 Valve 340793-762 Standardized Electrical Specs: Operates onThe Siemens LDU11. 523A17 Valve Proving System is a critical safety controller engineered for automatic gas valve leak testing in double block valve configurations. Operating on a 110 volt AC supply, this unit utilizes a rigorous two stage pressure proving principle to verify the integrity of shut off valves before burner startup or following a controlled shutdown. During Test1, the device evacuates the test space and monitors for atmospheric pressure
