Gas Valve Proving System for Gas Burners and Appliances

The LDU11xxx valve proving system was created for use with shutoff valves that are connected to gas burners and gas appliances. In the event of inadmissible leakage, the system prevents the burner from starting up. The gas valve proving system conforms to the requirements of EN1643 covering automatic shutoff valves for use with gas burners and gas appliances to EN161.

Dependable, the LDU11xxx is designed for automatic gas valve proving via a leakage test, based on the pressure proving principle, designed for use on gas-fired combustion plant with or without vent pipe to atmosphere. A lockout reset button with a viewing window is built in, showing the fault signal lamp and the lockout indication.

Used in connection with 1 or 2 commercially available pressure switches, valve proving is automatically initiated with every burner start-up, either prior to burner start-up, during de-purge, shutdown or the completion of a burner control sequence.

The valve proving test is based on the 2-stage pressure proving principle. The valve on the mains side is tested by evacuating the test space and by monitoring the atmospheric pressure in it.  The valve on the burner side is checked by pressurising the test space and by monitoring the gas pressure.
