PROTEGO® Pressure/Vacuum Relief Valves with Flame Arrester, end-of-line

The atmospheric deflagration-proof VD/TS type PROTEGO® valve is a highly developed combined pressure/vacuum relief valve for high flow capacities with an integrated flame arrester unit. It is primarily used as a device for flame transmission proof in-breathing and out-breathing on tanks, containers, and process equipment. The valve offers reliable protection against overpressure and vacuum, prevents the in-breathing of air and product losses almost up to the set pressure, and protects against atmospheric deflagration. The PROTEGO® flame arrester unit is designed to achieve minimum pressure drop with maximum safety. The PROTEGO® VD/TS device is available for substances from explosion groups IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm).
Benefits:
– 10% technology for minimum pressure increase up to full lift
– extreme tightness, resulting in lowest possible product losses and reduced environmental pollution
– due to 10% technology, set pressure is close to opening pressure for optimum pressure maintenance in the system as compared to conventional 40% or 100% technology
– valve pallet is guided inside the housing to protect against harsh weather conditions
– can be used as a protective system in areas with potentially explosive atmospheres in accordance with ATEX
– FLAMEFILTER® provides protection against atmospheric deflagrations
– integrated flame arrester unit saves space and reduces costs
– PROTEGO® flame arrester unit is protected from clogging and sticky products caused by product vapors
– minimum pressure loss of the PROTEGO® flame arrester unit
– high flow capacity
– maintenance-friendly design
– sturdy housing design
– best possible technology for API tanks
