S-TECH seismic valves are devices designed to automatically shut off the gas flow in earthquake situations under the conditions defined in the technical standard ASCE25-16, according to PED, ATEX directives and technical standards ANSI Z21. 21-2005, CSA 6.5-2005, CR90 – 002. It is a completely mechanical device which therefore does not require any electrical power supply.
When the device is subject to seismic vibrations as defined in the technical standards, the SV valve automatically cut-off the gas flow. After the automatic closure, the valve can be reset manually, and it remains closed unti l it is reset allowing the flow of gas.
It is the mechanical earthquake valve that perceives seismic movements [earthquake) and automatically shuts off the flow of gas at the places using gas at the end of perceived movements, then can be manually set up, stays turn-off until it is set up, and normally in turn-on position. The device automatically turns off at the moment of occurrence of the seismic activity having momentum and frequency values at the size depending on the related standards, as a result of perception of this activity by the device, and in a manner not causing leakage of flow of gas with help of gas shut-off equipment. Whether or not seismic activity continues or not, it remains turn-off until the flow of gas is set up again. It is possible to give gas to the installation again after device perceived seismic activities and shuts off gas, and the setup knob [reset) is manually pulled . After said shut-off, the manual setup proceeding must be definitely made by authorized gas distribution company or by firms authorized by them.
