V/SV-XXL Vacuum Relief Valve

Brand: PROTEGO
The V/SV-XXL type Protego valve is a highly developed optimized vacuum relief valve with excellent flow performance.

It is primarily used as a safety device for relieving vacuum in tanks, containers and process engineering equipment.

When the set vacuum is reached, the valve starts to open and reaches full lift within a 100% vacuum increase.

Up to the set vacuum, the tank vacuum is maintained with a seal that is far superior to the conventional standard due to the highly developed manufacturing technology.

This feature is achieved by valve seats made of high quality stainless steel with precisely lapped valve pallets and a reinforced housing design.

After the vacuum is relieved, the valve reseats and again provides a tight seal.
Features
  • Excellent tightness and hence least possible product losses and reduced environmental pollution
  • Very high optimized 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
  • Self draining
  • Maintenance friendly design
  • Best technology for API-tanks
  • Designed for use on cryogenic tanks
