Dungs SV-D 505 Safety solenoid valve Nominal width Rp 1/2 – Rp 2
Overview
The SV-D 505 is a gas solenoid valve with valve body, supplied as a safety shut-off valve for gas supply lines. As stated in the original listing, the DUNGS SV-D 505 valve is manufactured by DUNGS and carries order number 240334, and covers nominal widths from Rp 1/2 to Rp 2 with a maximum pressure of 500 mbar. The coil is rated 230 V, 50 Hz.
Gas solenoid valves of this type are the safety element of a gas train: they are held open electrically during normal operation and close automatically when the coil is de-energised, cutting the gas supply to the burner or appliance. This fail-safe behaviour is what makes the SV-D 505 suitable for safety shut-off duty in gas-fired systems.
Engineering & Design
The valve is a spring-return solenoid valve: when the 230 V 50 Hz coil is energised, the valve opens and allows gas to flow; when the coil is de-energised, the spring closes the valve positively. The design is rated for a maximum pressure of 500 mbar and is classified pressure class A, with a nominal width range of Rp 1/2 to Rp 2 as listed.
The body is fitted with a 1/2 inch pipe connection as per the original listing. Installation follows the normal gas train sequence, with the safety valve positioned so that the gas supply can be shut off positively when the burner control demands it.

Compatibility & Integration
The DUNGS SV-D 505 is installed in the gas train between the gas supply and the burner, upstream of the pressure regulator and the burner controls. Because gas train valves must match the system pressure rating, gas type and pipe size, confirm the nominal width and 500 mbar rating against the existing train before fitting.
Installation and commissioning of gas safety valves must be carried out by qualified personnel in accordance with local gas regulations. Our team can confirm the listed ratings against your application and advise on the correct spares for your gas train.
