Safe-Line® , Fully FEP/PFA Lined Safety/Pressure Relief Valves are manufactured with high accuracy to assure the performance of the valve, over protection for unfired pressure vessels/equipments and plant system from dangerously high pressure used with highly corrosive liquid, gases & vapors.
Size Range: 150 x 200
Set Pressure Range: 20 bar max. and Temperature 200 Deg. C
Safe and more reliable in corrosive services
Most economical & leadtime advantage over valves made of special alloy steel like hastelloy, titanium etc.
with corrosion resistant PU paint with Stainless Steel Fastners
Hermetic seal to valve bonnet and atmosphere, cancels out the effect of superimposed (constant and veriable) and built up back pressure.
for high flow rate
Fully locked in, unpigmented FEP/PFA uniform lining throughout body and face area helps to prevent blowout or collapse of the liner under full vacuum/high pressure
