Product Features & Overview
The Nabic Fig 500LF Flanged Pressure Relief Valve offers increased tightness on the discharge side, thanks to a resilient PTFE seat. This is coupled with a sealed spring cover to prevent leakage through the valve top due to back pressure. The lift is progressively proportional to flow.
As with the other high-quality valves in the Nabic range, the 500LF is WRAS Approved and is manufactured, tested and designed to the latest BS EN ISO 4126-1 standard. Dezincification resistance materials are used in the manufacture of all wetted parts. Drain plugs are also supplied on valves sized DN32 and above. Viton seat design valves are also available if required.
The valve is set to your chosen pressure at the factory, where it undergoes thorough shell and seat tests. A tamper-proof device is fitted to ensure safety. All Nabic valves ordered online come with a free pressure test certificate, providing unbeatable value for money. Letters of conformity can also be issued if needed.
This flanged pressure relief valve accomodates most flange standards. It has flanged inlet connections and threaded outlet connections (Rp parallel to BS EN 10226-1).
