Description
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
