Decompression valve for Barcelona cap

The Barcelona plug decompression valve is an essential safety device for releasing residual pressure in hydraulic networks and fire-fighting systems prior to any opening operation.

Comprising a main body, obturator and seal, this solution ensures controlled purging of the fluid (air or water), thus limiting the risks associated with opening under pressure.

Its sturdy, functional design makes it quick and easy to handle, adapted to the requirements of industrial environments and fire safety installations.

How the pressure relief valve works

Before removing a Barcelona plug, the valve gradually releases the pressure present in the network. This operation avoids sudden pressure release or splashing, which can lead to accidents or damage to equipment.

The user activates the valve to bleed off the pressure in complete safety, guaranteeing a controlled intervention in line with good maintenance practices.

Barcelona fittings and European standards

The Barcelona system is a connection standard used in Spain and other European installations. It differs from the STORZ or Guillemin (DSP/ARI) systems in its specific locking mode.

In this context, the integration of a decompression valve is an essential improvement to guarantee the safety of interventions on pressurized networks.
