Velan Inc products

All basic design features of Velan cast steel gate valves are adapted to special service conditions at cryogenic temperatures.

Velan pressure seal flexible wedge gate valves are ideal for high pressure steam (main steam isolation), liquid (feedwater isolation), catalytic reformers, hydrocrackers and other tough services.

Velan bolted bonnet flexible wedge gate valves are ideal for high pressure steam, catalytic reformers, hydrocrackers and other tough services.

Packing chamber has nickel overlay to protect from severe alkylation conditions and to guarantee low fugitive emissions.

Exclusive Memoryseal seats compensate automatically for wear and fluctuations of pressure and temperature.

Off-center split-body design allows the use of advanced spiral-wound gaskets.

The Velan Type MFA float trap automatically removes accumulated water from compressed air systems. Construction is similar to the Type MFT steam trap except that there is no thermostatic element. A boss is provided on top of the cover, tapped for a NPS 3/8 (DN 10) air circulating pipe which is necessary unless the trap is fitted directly under and so close to the drain point that air entering the trap can escape back through the inlet.

Long cycle life bellows (2000 cycles) in Gr. 321 (stainless) or Inconel. Designed for, and successfully tested in high pressure/temperature conditions.

Long cycle life bellows (2000 cycles) in Gr. 321 (stainless), Inconel for special applications, (may be replaced with Monel trim to resist corrosion or Hastelloy C for chlorine service).
