Safety and efficiency with the Dilock Slam Shut Valve

The Dilock Slam Shut Valve is a safety device (SAV) which quickly shuts off gas flow when the pressure it is monitoring reaches a pre-set limit due to any anomaly in the system, or when required by the operator at installation point or from remote point. The shut off is both over pressure & under pressure.
