Hydrofluoric Acid Alkylation Cast Carbon Steel and Monel ® Gate Valves

Features and benefits

• 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.
• All of the critical areas of castings are of RT quality in accordance to B16.34.
• 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.
• 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.
• Fugitive emissions qualified to API 624 and ISO 15848-1
• Flexible round wedge pioneered by Velan assures valve tightness and compensates for seat distortion and body deformation.
