[1] Description: Stelflow Range of unvented storage cylinders. The secondary circuit is
    fitted with a temperature and pressure relief valve set at 7.0 bar at 90°C and an
    expansion relief valve set at 6.0 bar. The product is supplied with a safety group
    consisting of a pressure reducing valve set at 3.0 bar, and an approved check valve
    cartridge, however, the complete product has not been fully tested to demonstrate it
    provides backflow protection. Also Supplied with an expansion vessel and tundish.
    
    Marking: Joule, model name, capacity, pressure ratings and other technical information
    on adhesive label on cylinder.
