DUNGS Valve Proving Module Control Unit (Valve Check) VPM-VC Series
The VPM-VC has been designed for automatic leak testing between two solenoid valves in gas-consuming devices, either prior to start-up or after switching off the system. The test system can be used as a single leakage tester or in combination with automatic burners. It is used in gas burner systems for heating, process heating, process industry and gas engines. The VPM-VC valve test module checks the tightness of burner gas shut-off valves in combination with one or two pressure switches. The test is performed in accordance with EN 1643. The program sequence, filling and venting parameters as well as program times can be adjusted by the user according to the system requirements.
- Control unit for system leakage tests according to En 1643.
- Checks tightness of the gas burner shut-off valves either before burner start or after shutdown.
- Equipment: one or two gas pressure switches.
- Additional pilot valves are required depending on the system
- ** Pressure switches/valves/pilot valves are not part of the scope of delivery!
Type VPM-VC Valve-check model versions : VPM-VC 24 VDC is suitable for the automatic leak-tightness tests between two solenoid valves in gas-consuming devices, either before start-up or after the system is switched off.
VPM-VC 24 VDC is the test system can be used as a single leakage tester or in combination with suitable control systems, e.g., PLC controls or automatic burner control systems. It is used in gas burner systems and gas engines. The valve test module according to EN 1643 for system leak-tightness tests checks the tightness of the gas shut-off valves in combination with one or two gas pressure switches. The program sequence, filling / venting variants, and program times can be adjusted by the user according to the system requirements. ** Additional auxiliary valves are necessary, depending on the plant and Pressure sensing devices / valves / auxiliary valves are not included in the scope of supply!
