Description
The SV/T-0-H type Protego valve is a highly developed vacuum relief valve with a valve housing that comes with a heating jacket down to the flange.
It is primarily used as a safety device for inbreathing to tanks, containers, and process engineering equipment under difficult operating conditions.
This includes extreme weather conditions or products that tend to form polymers at certain temperatures, adhere, or form deposits that negatively influence function (Such as bitumen, tar, dust).
The valve offers reliable protection against vacuum and prevents the intake of air close to the set vacuum.
Features- Excellent tightness and hence least possible product losses and reduced environmental pollution
- High flow capacity
- The valve pallet is guided within the housing to protect against harsh weather conditions
- Can be used in areas subject to an explosion hazard
- Complete heat jacketed design down to the flange to avoid cold bridges
- Maximum permissible heating medium temperature of 320° C (608° F) at psi: 87 (kPa: 600, bar: 6)
- A special design that preheats incoming air is also available
- A special design with a heatable valve cover is also available
- The valve pallet cover prevents the set pressure from being distorted by dust or condensate
- Reinforced housing design
- A special design with a mechanical vent pallet lift device is available
