Leser Type 526 API Safety Valves
API
Flanged Safety Valves that meet all the requirements of API 526 such as standardized orifices and center-to-face dimensions. Their robust construction makes them especially suitable for high pressures and materials like Duplex, Monel or Hastelloy.
ADVANTAGES
100% Compatibility to API 526
Single Trim (identical internal parts for steam/gas/liquids) allows economical maintenance
Quick delivery (2 - 4 weeks from the factory or next day from local warehouse)
Quick delivery for high-alloy materials
Longer valve lifespan due to hardened disc and (partially) stellited seat
Longer lifespan of optional bellows through integrated shielding
