ER/V Emergency Pressure Relief Valve

Brand: PROTEGO
Request Information
The ER/V type Protego valve is a highly developed emergency pressure relief valve with high flow capacity. 

It is primarily used as a safety device for emergency pressure relief for storage tanks, containers, silos, and process engineering equipment; it offers reliable protection against overpressure and prevents impermissible product vapor loss close to the set pressure. 

It is designed to relief particularly large amounts to prevent the vessel from rupturing in an emergency case.
Features
  • "Full lift type" technology valve utilizes only 10% overpressure to reach full lift
  • Excellent tightness and hence least possible product losses and reduced environmental pollution
  • The set pressure is close to the opening pressure which results in best possible pressure management of the system
  • High flow capacity
  • The valve pallet is guided within the housing to protect against harsh weather conditions
  • Can be used in areas subject to explosion hazards
  • Reinforced design
  • Safely secured housing cover
  • Best technology for API-tanks
