Cast steel API 600 valves with industry-leading emissions, shutoff and repairability performance. Body/bonnet wall thickness is in accordance to higher limits of API 600 offering one of the highest corrosion resistance capacities in the market. HF acid detecting paint allows for an immediate visual detection when exposed to acid or acid vapors to ensure valve integrity. Flexible round wedge pioneered by Velan assures valve tightness and compensates for seat distortion and body deformation.
  • Packing chamber has nickel overlay to protect from severe alkylation conditions and to guarantee low fugitive emissions

  • Stem is made from solid age hardened K-Monel® 500 for increased strength and corrosion resistance.

  • Bonnet joint is precision machined and has a special surface finish for extended service life

  • Monel® seats are single seal welded-in using state-of-the-art metallurgical technology to ensure zero leakage behind and around the seats, preventing in-service corrosion

  • Fully encapsulated gasket design with metal-to-metal body to bonnet contact for optimal and controlled gasket compression
