SV/E Vacuum Relief Valve
Brand: PROTEGOThe deflagration-proof SV/E type Protego valve is a state of the art vacuum relief valve with an integrated flame arrester unit.
It is primarily used as a safety device for flame transmission proof inbreathing on tanks, containers and process engineering apparatus.
The valve offers reliable protection against vacuum and prevents inbreathing of air almost up to the set pressure; it also protects against atmospheric deflagration.
The Protego flame arrester unit is designed to achieve minimum pressure drop with maximum safety.
The Protego SV/E valve is available for substances from explosion groups IIA to IIC.
Features- Requires only 10% overpressure to full lift
- Extreme tightness and hence least possible product losses and reduced environmental pollution
- Through 10% technology lower set vacuum can be reached which results in product loss reduction compared to conventional 40% and 100% overpressure technology vents (compare API 2000)
- Optimized flow performance
- The valve disc is guided within the housing to protect against harsh weather conditions
- Can be used as protective system according ATEX in areas subject to explosion hazards
- FLAMEFILTER provides protection against atmospheric deflagration
- FLAMEFILTER integrated into the valve saves space and weight
- FLAMEFILTER protected from clogging through product vapor
- PROTEGO flame arrester unit has a low pressure drop
- Maintenance friendly design
- Modular design enables individual FLAMEFILTER and valve pallets to be replaced
