Description
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
