V/KSM Vacuum Relief Valve

Brand: PROTEGO
Request Information
The Protego valve V/KSM is a state-of-the-art vacuum relief valve with excellent flow performance made of high grade synthetic material. 

It is used as a safety device to relieve vacuum in tanks, containers, and process engineering equipment; it prevents the inbreathing of air until reaching the set vacuum. 

The valve is a perfect solution for corrosive, polymerizing or sticky media. 

The device will start to open as soon as the set vacuum is reached and is fully open within 10% vacuum increase. 

Continuous investments into research and development have allowed Protego to develop a low pressure valve which has the same opening characteristic as a high pressure safety relief valve. 

This "full lift type" technology allows the valve to be set just 10% below the maximum allowable working vacuum (MAWV) of the tank and still safely vent the required mass flow.
Features
  • "Full lift type" technology valve utilizes only 10% overpressure to reach full lift
  • Extreme 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
  • The valve pallet is guided within the housing to protect against harsh weather conditions
  • Corrosion resistant valve
  • Perfect solution for corrosive, polymerizing and sticky media
  • Weight reduction in comparison to steel/stainless steel
  • Smooth surface
  • Automatic condensate drain
  • Different plastics can be combined
  • Maintenance friendly design
