Product Features & Overview
The Nabic Fig 542LF Flanged Pressure Relief Valve is a very popular, high-quality item which is suitable for liquids and inert gases. It offers a high degree of seat tightness, particularly on the discharge side, thanks to its durable PTFE seat design, which also ensures that the valve's lift is proportionate to its flow.
It is fully WRAS Approved and has been designed and tested to BS EN ISO 4126-1 standard to ensure quality and peace of mind throughout. All wetted parts are manufactured from dezincification resistance materials. The Nabic 542 LF also features a sealed spring cover, stopping any back pressure leakage from the valve top.
Before the valve leaves the factory, Nabic perform strenuous shell and seat testing to confirm set pressure. This pressure setting is then locked and sealed, and a tamper-proof feature is also added.
