SCN

The SCN is a compact safety device (SAV) which quickly intercepts gas flow whenever the pressure under monitoring reaches a pre-set limits, or whenever manually required by operator on site or through a remote command (optional device). SCN is a slam-shut valve with self-operated actuation and manual resetting, it is an ideal product for distribution networks and industrial and chemical engineering applications. SCN is suitable for natural gas and all non-corrosive gaseous media. Its 'top entry' design makes it easy to maintain without removing the body from the pipeline. Main features • Intervention for overpressure and/or underpressure; • Manual push-button control at installation point; • 3 way solenoid valve for remote control (available on request); • Manual re-setting; • Internal by-pass for pressure equalization before resetting • Possible installation in any position although installation on horizontal pipes is recommended.
