Pressure-relief equipment for protection of tanks and process equipment

Our range of pressure-relief equipment includes:

  • Pressure/vacuum valves to protect the tank from damage caused by overpressure or excessive vacuum
  • Flame arresters to protect flammable liquids from external sources of ignition
  • Rupture discs for protection of equipment, tanks, systems and people against excess pressure
  • Measuring hatches
  • Excess pressure valves
  • Etc.

Our pressure-relief equipment can be supplied with full documentation – including ATEX, FDA, USP Class VI and more – and is used, e.g., to protect:

  • Refineries
  • Chemical processing plants
  • Oil storage tanks with fixed roof
  • Process vessels and piping
  • Fermentation containers
  • Clean-steam pipe
  • WFI containers and pipes
  • CIP & SIP piping
  • Lyophilizers (freeze-drying)
  • Mixing, drying, granulating equipment
  • Filters
  • Autoclaves
  • Bioreactors
  • Heat exchangers
  • Storage and transport containers
  • etc.

Pressure-relief equipment with long-lasting solution

Do you work in the process/chemical industry, the pharmaceutical industry or the food industry, and do you need to be able to protect your tanks and process equipment from overpressure, vacuum or fire hazard? Then pressure-relief equipment from our selection will definitely be suitable for you.

For demanding tasks and aggressive media, it is important that your equipment is completely in order. Therefore, all pressure-relief equipment from Alflow is type approved. In addition, it meets industrial requirements in relation to use, hygiene, environment and serviceability. This ensures that it is easy to service our pressure-relief equipment. This means that you are guaranteed investment in a product that lasts well into the future.

You can choose to have the pressure-relief equipment delivered with the current certificates, which are suitable for several industries. You can, e.g., come across certificates such as ATEX, FDA and USP Class VI.

At Alflow, we also want to supply the best pressure-relief equipment on the market. This can be seen, e.g., by the fact that our models are extremely durable as they are produced in the most suitable material in terms of application possibilities. By purchasing pressure-relief equipment from Alflow, you get a long-lasting solution.

Our range of pressure-relief equipment includes, e.g., gauge hatches that provide quick access to measure or obtain product samples from storage tanks at the same time as functioning as emergency ventilation. The gauge hatches are designed with a foot plate to prevent the foot from slipping when you open it, and the cover closes by means of gravity when the foot is removed from the cover.

We also have both industrial and sanitary pressure-relief valves. The industrial pressure-relief valves are calculated according to tank size and mode of operation and protect the tank from damage that can be caused by excess pressure, through venting to the open air. Less evaporation due to the fact that normal “breathing” in the tank is reduced. The industrial pressure-relief valves can be used for emergency relief on smaller tanks.

Our sanitary pressure-relief valves are DESP-certified safety equipment designed to protect production lines and tanks containing group 2 gas, steam or liquids from against excess pressure. They are manufactured in a hygienic design and they are fully automatic so they require no manpower to operate them.

Our flame arresters for gas piping systems and protection of tanks containing flammable liquids protect low flash-point liquids from external sources of ignition and increase fire protection and safety. The flame arresters are available in both vertical and horizontal models.

We also have a wide selection of industrial and sanitary pressure/vacuum valves. Our industrial pressure/vacuum valves can be used in many applications to protect the tank from damage that can be caused by excess pressure or vacuum. They are available as pilot-controlled relief valves, modular vacuum valves and pressure/vacuum valves with a built-in flame arrester.

Our sanitary pressure/vacuum valves are hygienic equipment designed to protect tanks against pressure fluctuations (vacuum switch) and excess pressure or to protect low pressure tanks that are not subject to DESP against dents (vacuum switch) and/or excess pressure.

We also sell rupture disc for protection of equipment, tanks, systems and people against excess pressure conditions. Advanced tooling processes and optimal material thickness ensure full openings and accurate fracture classifications in each installation. The rupture discs are calculated exactly for any application and are suitable for liquid, gas and steam.
