Safe-Line BTSC 50 BL: Brightech™, 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: 15mm X 25mm to 150mm X 200mm
Pressure Rating: Class 150

Features & Benefits

• High Performance

  Safe and more reliable in corrosive services

• Standard Design

  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

• Liner Locking

  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

Construction

• 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 low pressures < 1 Kg almost consistent performance
• Resets and shuts off the pipeline/equipments after operation
