ER-V-LP Emergency Pressure Relief Valve

Brand: PROTEGO
Request Information
The Protego type ER-V-LP valve is a sophisticated pressure relief valve for applications in which a high flow efficiency is of the essence. 

It is primarily used as an emergency pressure relief valve on storage tanks, vessels, silos, and process engineering equipment. 

It offers reliable protection against excessive over-pressure and prevents excessive product loss at pressures as high as close to the set-to-operate pressure. 

It is designed to relieve particularly large quantities to prevent the vessel rupturing in an emergency case.
Features
  • Patented valve pallet technology guarantees that minimum leakage-rate requirements can be met and, hence, least possible product losses and reduced impact on the environment are ensured
  • 10% Technology for minimum pressure increase until full lift
  • Set-to-operate pressure close to the opening pressure; hence, best possible pressure management of the system
  • High flow efficiency
  • Valve pallet is guided within a closed system and, thus, protected from atmospheric influence
  • Suited for use in hazardous areas
  • Rugged body design
  • Movable components are secured
  • Best technology for API tanks
