EF/V-IIB3 Detonation Flame Arrester

Brand: PROTEGO
Request Information
The Protego EF/V-IIB3 detonation-safe foot valve protects the suction line in a storage tank. 

The nearly service-free device is installed at the end of the emptying line within the tank. 

When a pump draws, the valve opens at an approximate under pressure of psi: 0.43 (kPa: 3, mbar: 30) 12 Inches WC. 

When the pump is turned off, the device functions as a check valve and prevents the line from emptying. This is very helpful when the pump is restarted.
Features
  • Almost service-free
  • The check valve makes it easier to start the pump
  • Provides protection from deflagrations and stable detonations
  • Applicable to nearly all flammable liquids
  • Meets TRbF (Technical Regulations for Flammable Liquids) 20 requirements
  • The special strainer prevents solid particles from entering
