Three-layer safety plates


Three-layer safety plates are applied mostly for low, medium and high operating pressures. The solutions offered can operate at the level of 80% of the plate bursting pressure. Special bursting points (Bursting Discs), incised with a laser beam, ensure a high precision of the plate action and, in combination with a sealing membrane, determine the bursting pressure. Additionally, in case of very high bursting pressures, plates with a star-shaped incision are applied, which guarantees a lack of fragmentation after action.
To achieve the highest possible precision of action, the bursting points have been made with the use of the newest laser technology. The integrated strengthening guarantees resistance to action of vacuum, irrespective of the plate dimension.
In the case of the applications where corrosion may be a problem, the element that is subject to bursting is protected by means of a sealing membrane made in a standard way of FEP/PTFE. For high bursting pressure values, the membrane may also be made of stainless steel.

  • Minimum bursting pressure: 0.015 bar(g)
  • Dimension: 20-1400 mm
  • Max. admissible operating pressure: up to 80% of bursting pressure
  • Installation: between flanges in an integrated head and a tri-clamp type holder
  • Construction: three-layer
  • No fragmentation after action
  • Long life span
  • Suitable for pulsating pressure
  • Liquid and gaseous media

safety plates

Single-layer safety plates are intended mainly for simple applications and high bursting pressures. The plates have been designed so that the bursting pressure is a resultant of selection of the proper thickness and strength of the material used.

For sanitary
and aseptic applications

Safety plates are intended for sanitary and aseptic applications, therefore, they are a perfect solution for pharmaceutical, biotechnological and food industries. Moreover, due to their properties, they can be successfully applied for gases, vapours and liquids.

Bilateral action
safety plates

Bilateral action safety plates substitute two standard plates due to their unique construction. The important thing is that the device offered can have different opening pressure values for over- and underpressure.

Heads for safety
plate installation

The heads are used for trouble-free mounting of safety plates with the use of flange, welded or screwed connection. This solution provides for a high tightness of the system, a proper plate operation and a long life span.
