VD/KSM-PA Pressure & Vacuum Relief Valve

Brand: PROTEGO
The Protego valve VD/KSM-PA is a state-of-the-art pressure and vacuum relief valve with excellent flow performance made of high grade synthetic material.

Typically the valve is installed in the in-and out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure.

The valve prevents emission losses almost up to the set pressure.

The valve is a perfect solution for corrosive, polymerizing or sticky media.
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
  • Vacuum side self draining and pressure side condensate drain
  • Smooth surface
  • Different plastics can be combined
  • Maintenance friendly design
