Corrossive Service PSV
R014 Series Safety Relief Valves – Special Corrosive Service
REGPORT offer special design with PTFE seating for the corrosive media like acidic or base vapors, wherein metallic nozzle and disk are not preferred due to either compatibility or cost involved.
In this specific design, the Nozzle is made up of PTFE and the disk shall be GFT. This provides excellent seating and ensures as good as zero leakage through valve when it is closed. Also, we provide PTFE/Halar coating to the body and bonnet from inside to ensure the corrosion resistance in the event of opening of the safety relief valve. Special arrangement for holding the PTFE Nozzle is provided. The internals like Disk Holder, Stem and Guide are provided in AISI 316L to facilitate the corrosion resistance.
Eminently installed on GLR, HCL, Chlorine or excessively corrosive fluid lines, mainly in Pharmaceuticals or Chemical Plants as these provide a cost effective solution as compared to combination of PTFE Rupture Disc with SS Safety Relief Valve.
