BRONZE SAFETY RELIEF VALVE


  • Designed to relieve overpressure in a piping system containing compressible or incompressible fluids.
  • It is the preferred solution for automatically relieving overpressure in boilers, pressure vessels or other systems when the pressure and / or temperature exceeds the allowable limits.
  • Design in accordance with ASME B16.34 design requirements.
  • Bronze safety valve classes: 250 x 300 (steam) 350 (air).
  • Bronze relief valve classes: 300 psig except NPS 3 which is 150 psig.
