PF SCN Slam Shut

PF SCN Slam Shut Safety Device

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.
