SD/BS-H Pressure Relief Valve
Brand: PROTEGOThe SD/BS-H type Protego valve is a highly developed pressure relief valve with a heating jacket down to the flange.
It is primarily used as pressure relief device for vessels 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 overpressure and prevents the unacceptable loss of product vapors close to the set pressure.
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
- Set pressure is close to the opening pressure which results in best possible pressure management of the system
- 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
- Heating 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 with a heatable valve cover is available
- At low pressure settings, an optimized 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
