V/KSM Vacuum Relief Valve
Brand: PROTEGOThe 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
