Fort Vale – Super Maxi Highflow
The Super Maxi Highflow valve is a safety valve with 2½” outside BSP thread and is available in a pressure/vacuum version and a pressure version. Designed in cooperation with leading tank builders and users (in the UK), it meets even the strictest requirements on modern tank trucks, railway cars, container vessels and stationary tanks.
The valve is made of stainless steel type 316. Precision work, made with the newest CNC tools. The seal material is Viton ”A” or TYTAN, one PTFE (Teflon) pressure/vacuum seal in each.
The Tytan seal is the result of a very long research carried out by the Fort Vale design team. It is made of hard PTFE (Teflon) and is designed in such a way that there can be an O-ring on the opposite side. This gives the seal the same efficiency as rubber and the same resistance to chemicals as PTFE (Teflon). It is best suitable for tanks used for transport of liquids, the vapours of which are both destructive and toxic or combustible.
- Standard size 2½” BSP thread outside
- Alternatively available with flange
All parts are made of stainless steel type 316, the cabinet of type 304 S12, electro-polished. - For optimum seal efficiency in the entire service lifetime, the valve has been designed with non-metallic seals of a corrosion resistant material, e.g. Viton ”A” or Tytan.
- Maximum venting capacity has been ensured through the careful design of the venting ports and the pressure plate.
- With the pressure-vacuum valve, there is no need for separate pressure and vacuum valves.
- All valves are checked for both pressure and vacuum, stamped with the setting, and are then closed and sealed.
- Test certificates can be delivered.
- Flame protection for the valves can be delivered.
Service
The valve should be inspected every six months to ensure the safety and the stable function.
The valve has a number of standard settings from 1 to 4 bar on the pressure side and 6” Hg on the vacuum side.
Bursting discs
