Safe-LineTM , 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
Features & Benefits:
Safe and more reliable in corrosive services
Most economical & leadtime advantage over valves made of special alloy steel like hastelloy, titanium etc.
Cast Ductile Iron Body
with corrosion resistant PU paint with Stainless Steel Fastners
PTFE Balance Bellows
Hermetic seal to valve bonnet and atmosphere, cancels out the effect of superimposed (constant and veriable) and built up back pressure.
High Discharge Coefficient
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
Safeguarding of pressure vessels and plant systems against overpressure. Set pressure up to 15 Kg & max. temperature 180°C
Corrosive media, where metallic materials can not reach an adequate service life or where special metals cause high costs
Used where over protection for unfired pressure vessels/equipment and plant system from dangerously high pressure used with highly corrosive, gases & vapors.
Direct acting, spring loaded PTFE balance bellows safety relief valve with angle type valve body
Standard safety valve, design and performance complying with the requirements of ASME Section VIII
Opening characteristic similar to full lift and streamline-designed flow parts result in high discharge coefficients , thus achieving high discharge capacity
At very low pressures almost consistent performance
Resets and shuts off the pipeline/equipments after operation
