- Page 3 GENERAL PRODUCT INFORMATION: S-TECH is a trademark owned by Gas Broker srl used for the marking and distribution of seismic valves model SV. The use of gas valves with automatic seismic action with manual reset is recommended, and it is also, in some cases, a legal obligation, to prevent damage caused by an earthquake from adding other damage due to fire or explosion caused by the consequent gas leaks.
- Page 4 Before proceeding with the assembly, it must be ensured that the SV seismic valve to be installed is suitable for the place in which it will be used both for the presence of an area classified as dangerous for explosion and for the pressure rating of the piping.

Page 5: Safety Instruction
This situation must be guaranteed for the entire duration of the installation and blank testing operations until the valve is put into operation. The SV model seismic gas valve is a device whose safety is provided for use in hazardous areas classified as surface for group IIB gas (propane, methane, etc…). - Page 6 Installation near regulation and measurement groups If the SV valve is installed in the immediate vicinity of regulation and measurement groups and / or is incorporated in the same protection cabin / cabinet, all the precautions and design and safety requirements provided for by the EN 12279 and EN 12186 standards must be respected.
- Page 7 ISTRUCTION FOR INSTALLATION, USE AND MAINTENACE OF THE SEISMIC VALVE SV The SV valve incorporates a bubble viewer as in the spirit levels, to indicate its correct positioning and consequently its operation; if the valve is installed correctly, the bubble must be positioned in the center of the...
- Page 8 Atex marking; • The mechanical installation must be made so that in subsequent operation the SV seismic valve itself is not subjected to vibrations, abnormal temperatures, stray currents or currents due to cathodic protection devices; •...
- Page 9 COMMISIONING For installation on the methane gas distribution network, the risk of formation of explosive mixtures (gas / air) inside the pipes must also be considered. After installation, check that the inlet and outlet on-off valves, any by-pass and the relief valve are all closed. Before proceeding with commissioning, it is recommended to check the external tightness of the system, checking for any gas leaks / leaks.
- Page 10 RESET AND DEVICE ACTIVATION Please inform the competent authorities in case the device is activated following an earthquake. Before proceeding with the reset, you must check that there are no gas leaks. Procedure for resetting, see the images below P a g e . 10 | 15...
- Page 11 - Figure 1 shows how the product will be delivered (seismic valve and pin in the same packaging but separate). - Figure 2 shows how the pin is screwed into the stem to proceed with the reset. - Figure 3 shows how the reset is activated by pulling the pin screwed onto the reset stem. - Figure 4 shows the direction to reposition the pin.
- Page 12 WARNINGS / INDICATIONS ON THE PRODUCT ATTENTION! This device must be installed by a qualified technician according to the regulations in force; if installed improperly, it could cause non-functioning such as intentional or unjustified interruption of the gas supply service. FLOW / ARROW = the seismic valve must be installed respecting the flow direction indicated by the line with the arrow on the body, paying attention to the maximum operating pressure.
