VPS504S04 / VPS504S05 (DUNGS Gas Valve Leakage Testing Device)
Brand: DUNGS (Germany)
Type: Combustion System Dual Solenoid Valve Leakage Testing / Monitoring Device (Compliant with EN1643)
I. Application
Specifically designed to detect leakage in dual gas solenoid valves (e.g., the DMV series) after valve closure.
Used in boilers, burners, and gas heating equipment to prevent gas leakage and potential explosions.
Applicable Gases: Natural gas, town gas, LPG (Gas families 1, 2, and 3).
II. Common Core Parameters (S04 / S05)
Operating Pressure: ≤ 500 mbar
Test Volume: ≤ 4 L
Test Duration: 10–26 s (Automatic)
Pressure Boost: +20 mbar (via built-in electric pump)
Output Contacts: Operating Output 4 A; Fault Output 1 A
Indicator Light: OK (Sealed) / Fault (Leaking) — Dual-color LED
Installation: Vertical or horizontal; must not be mounted upside down.
Certifications: EN1643, TRD Compliant
III. Model Differences (S04 vs S05)
VPS504S04
Power Supply: AC 230–240 V / 50–60 Hz
Wiring: PG13.5 Cable Gland + Screw Terminals
Function: External Fault Indication (Supports connection to remote alarms)
VPS504S05
Power Supply: AC 230–240 V or DC 24 V (Dual power supply for greater flexibility)
Wiring: Same as S04 (PG13.5)
Function: Same as S04 (External Fault Indication)
IV. Operating Principle (Brief Overview)
After the burner shuts down, the VPS504 automatically initiates the leak test.
The built-in pump pressurizes the chamber between the two valves by +20 mbar.
The pressure is held for 10–26 seconds while monitoring for any pressure drop.
No Pressure Drop = Good Seal (Green Light); Excessive Pressure Drop = Leak Detected (Red Light + Fault Contact
VPS504S02
Voltage: AC 230V ±10% / 50–60Hz
Power Consumption: Approx. 15VA
Connection Method: Built-in standard socket (DIN4791); allows for direct plug-in connection without the need for rewiring.
Difference from S04/S05: The S04/S05 models utilize a PG13.5 cable gland and screw terminals, whereas the S02 features a socket-style connection, enabling faster installation.
