BE/HR-D Pressure Relief Valve
Brand: PROTEGOThe deflagration-proof and endurance burning-proof BE/HR-D type Protego valve is a highly developed pressure relief valve with an integrated flame arrester unit.
It is primarily used as a safety device for flame transmission proof outbreathing on tanks, containers and process engineering apparatus.
The valve offers reliable protection against excess pressure and prevents product losses almost up to the set pressure; it also protects against atmospheric deflagration as well as endurance burning if stabilized burning occurs.
The Protego flame arrester unit is designed to achieve minimum pressure drop with maximum safety.
The BE/HR-D valve is available for substances of explosion group IIA (NEC group D MESG >0.9 mm).
Features- Requires only 40% overpressure to full lift
- Through 40% technology higher set pressures can be used which results in product loss reduction compared to conventional 100% overpressure technology vents (compare API 2000)
- More design flexibility through higher reseating pressures
- High performance seal reducing product loss below 500 ppm rule preventing environmental pollution
- The valve disc is guided within the housing to protect against harsh weather conditions
- Can be used as protective system according to in areas subject to explosion hazards
- High flow capacity through large FLAMEFILTER cross-section, results in low pressure drop
- FLAMEFILTER provides protection against atmospheric deflagration and endurance burning
- FLAMEFILTER integrated into the valve saves space
- FLAMEFILTER protected from clogging through product vapors
- Flame-transmission-proof condensate drain
- Maintenance-friendly design
