PROTEGO® Soupapes de surpression et dépression

Technologie

Un réservoir fermé ou citerne de stockage de liquide doit présenter une ouverture permettant à la pression de se décharger, de façon à éviter au récipient d’exploser. Il est, de même, nécessaire de compenser les dépressions qui résultent des soutirages pour éviter au réservoir de s’imploser. Les soupapes de surpression et dépression PROTEGO® sont équipées de clapets tarés par masse de tarage. Lors d’une surpression dans le réservoir, le clapet de surpression guidé dans le corps se souléve et libére le gaz dans l’atmosphére tant que la pression reste supérieure à la pressionn  de tarage. Si le réservoir est en dépression, la pression différentielle sur la clapet de dépression le fait se lever permettant ainsi l’entrée d’air dans le réservoir.

Gamme de produits:

  • Soupapes de surpression et dépression (Appareils de bout de ligne ou appareils en ligne)
  • Soupapes de surpression et depression à arrête-flammes (Appareils de bout de ligne)

Adavantages particuliers:

  • High flow capacity
  • PROTEGO® Valves open later and close earlier ensuring optimized pressure management and saving of inert gases
  • Reduction of product losses
  • Improved tightness

Soupapes de surpression et dépression

PROTEGO® pressure and vacuum relief valves with full-lift pallet discharge the flow within 10% overpressure from the set pressure to a fully opened valve (full-lift).

Les suopapes PROTEGO® sont conçues de façon standard pour cette technologie de 10%, sauf autre accord.

Advantages de la technologie 10% PROTEGO:

  • Maintien de pression jusqu’à une pression peu inférieure à la pression maximale admissible
  • Réduction maximale des pertes de produit 
  • Réduction des émissions

Vapor Savings

Vapor saving potential for 10% full lift type valve compared with 100% overpressure valve. Using a full lift type technology valve (valve requiring only 10% overpressure to reach full lift and provide full performance) can result in additional 44%:


Souplesse de leur diaphragme

La souplesse de leur diaphragme fait utiliser ces soupapes aux basses températures saisonniéres et, avec diaphragme en FEP, pour des liquides collants ou polymérisant. Les soupapes à diaphragme PROTEGO® sont les seules au monde à pouvoir fonctionner jusqu’à -40°C.

Benefits of PROTEGO® Diaphragm Valves

  • high performance seal reducing product loss below EPA’s 500ppm rule preventing environmental pollution
  • set pressure close to opening pressure enables optimum pressure maintenance in the system
  • liquid column height is monitored by level indicators (see picture on the right)
  • freeze protection at sub-zero conditions (see picture 1 on the back)
  • hinged design – maintenance friendly (see picture 2 on the back)
  • self draining function for condensate
  • particularly suitable for problematic products such as monomers,polymerizing media and vapours with a tendency to condensate, etc.

Soupape pilote PROTEGO®

La soupape pilote PROTEGO® est autonome et évacue le débit sans avoir besoin d’une surpression. Les soupapes pilote PROTEGO® s’utilisent, pour l’essentiel, comme soupapes de décharge sur les réservoir à basse température ou lorsque la soupape doit rester particulièrement étanche jusqu’à la pression de réponse.

Soupapes d’évent d’urgence

Si un feu, à l’extérieur du réservoir, ou le dysfonctionnement d’un équipment spécial  impose un débit d’évent extrêment élevé, des soupapes d’évent d’urgence supplémentaires doivent être mises en service.

PROTEGO® Leak Rates

The maximum permissible leak rates for PROTEGO® valves are listed in the table. We differentiate between the standard leak rate A and the special leak rates B and C. The latter require a valve pallet in metal-to-metal contact. The special leak rate C can be applied to valves having a minimum set pressure of 50 mbar or a set vacuum of 14 mbar. The standard leak rate A and the special leak rate B apply by analogy to below-atmospheric pressure uses. Liquid-loaded diaphragm valves are principally tested using the special leak rate B.
