• Cost efficient spare parts
• Provides protection from deflagrations and stable detonations
• Ideal protective system for vacuum pumps

The PROTEGO DR/SV flame arrester series ideally combines the function of a detonation arrester with the advantages of a cut-off valve. In case of ignition, the fire can be stabilized within the flame arrester when the flammable gas continues to flow. Inside the detonation arrester, is a valve that closes in case of fire, stops the additional supply of fuel and extinguishes the flames. Temperature sensors in combination with an emergency switch off do not have to be installed when a type PROTEGO DR/SV device is used. This device is particularly useful for the intake-side protection of compressors and pumps.
The flame arrester protects against deflagrations and stable detonations. It can be installed anywhere in the pipe independently from the distance of the potential ignition source.

• The special strainer prevents solid particles from entering

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 underpressure of 30 mbar / 12 In W.C. . 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.
Combustible mixtures can arise in filling and drain lines of storage containers that are not always filled with product. With the ignition of the explosive atmosphere, highly accelerated pipe deflagration or detonations can arise. The detonation-proof foot valve prevents the combustion from being transmitted into the tank and destroying it. The design of the foot valve ensures that the strainer is always filled with residual product. Together with the special valve design, this combination prevents flame flash back from the inside out.
