  safety relief valve
  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 100mm X 150mm
Pressure Rating: Class 150

  Standard Specifications
  Direct acting, spring loaded, full lift safety relief valve with angle discharge
  ANSI, #150 Inlet & Outlet RF Flanges
  PTFE Balance Bellows design
  Compatiable with API 526 Center to Face line dimensions
  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

  Feature & 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
