Multi-Purpose Safety Relief Valves, for Liquid, Gas & Steam Applications

The Seetru LGS® Safety Relief Valve range represents state-of-the-art design with dual guided spindle as well as the Seetru Rock-Seal™ seal technology for repeatable high performance sealing.

The Seetru LGS® safety relief valve is a high quality valve of modular design and construction incorporating the Seetru proprietary compact design technology – providing a highly cost-effective range of valve solutions.

LGS® valves have a robust and reliable construction designed for the widest range of industrial applications. The LGS®range is suitable for a wide variation in flow characteristics, coping with both low volume and high relief capacity applications.

The single trim design means that the components are all common across liquid, gas and steam; and that any LGS® valve can be used in any of these applications.
