DR/ES-V In-Line Detonation Flame Arrester

Brand: PROTEGO
Protego DR/ES-V series uniquely combines the function of a in-line detonation flame arrester with the function of a pressure relief valve in one device. 

The device protects against deflagration and stable detonation. 

The weight-loaded pallet type valve integrated in the shock absorber of the in-line detonation flame arrester is designed as pressure relief valve. 

The set pressure of the valve is adjusted in the factory and can range from psi: 0.029 to 0.50 (kPa: 0.2 to 3.5, mbar: 2 to 35) (Inches WC: 0.8 to 14).
Features
  • Integration of in-line detonation flame arrester and pressure relief valve in one device
  • Excellent tightness of the valve
  • Applicable as a detonation-proof check valve in suction lines of storage tanks
  • Optimum for use as an overflow valve in venting and recovering vapor lines
  • Minimum number of FLAMEFILTER discs due to the effective shock absorber
  • Quick removal and installation of the complete PROTEGO flame arrester unit and the individual FLAMEFILTER discs in the cage
  • Provides protection from deflagration and stable detonations
  • Extended application range for higher operating temperatures and pressures
