DESCRIPTION

The louver dampers are, as the word well says, valves that allow or restrict the entry or exit of air, water, gas, etc. by means of a series of slats. These are used in oil fields and refineries, factories, ships, military bases, storage rooms for chemicals, paints or hazardous materials, underground facilities or nuclear power stations, and fulfill the function of control and / or isolation. 

The louver valves are made up of: a frame and some louvers or leaves.

The most common materials with which the Valves are manufactured are aluminum and galvanized, stainless or mild steel and can have different shapes (square, rectangular or round) and openings / closures (manual, mechanical, electrical, pneumatic, hydraulic).
The valve slats can be of two types: aerodynamic or normal. They can also have, if needed, thermal insulation.

The valve slats, depending on their orientation, have one function or another. Within them we could distinguish between:
  • Parallel blades: all their blades rotate in the same direction. It can offer up to 99% tightness. They are mainly used for isolation.
  • Opposite slats: adjacent slats rotate in opposite directions. It allows you to gradually increase or decrease the flow, which allows you to have very good control characteristics. They are used for gas control.
  • Double slats: designed to create insulation without any leakage, by means of a hermetic seal.
  • Tandem: works in the same way as the double blade valve, with the difference that, instead of having the hermetic seal between sheets, it has it between the tandem vane liners wider.
Valves can have a flexible or non-flexible seal, depending on specifications.
In the marine environment, the Valves are used in emergency generating systems, for fire control, ventilation of the engine room, for hermetic closures … etc. These can be found both on the deck and in the interior of the boat.
The flap valves, apart from being created to be able to resist corrosion and the high temperature range of a fire, can also be designed to withstand explosions, which makes them highly safe.

We offer a totally customized design and manufacture of flap valves. We fully adapt to our client’s requirements, no matter how demanding. 

We offer Valves made with top quality materials, so that the product can have a greater and better performance, and it obtains a maximum useful life.

When designing them, we study the different possibilities that exist, to offer the highest quality, as well as the creation of a Valve that has the fastest possible response, so that in case of emergencies, no type of problem arises.

We create Valves for both land and maritime areas, using different materials, seals, closures and drives. Always choosing those materials that are most suitable and will best fulfill their function.

DESCRIPTION

The Valves can be actuated by different actuators, which are: 

  • Electrical.
  • Tire.
  • Hydraulic.
  • Mechanics.
The mechanical opening is generally used when a very tight seal is required, or when it has to act against air pressure. In any case, it is possible to complement any of these actuators with a manual actuator, which will be of great help in situations of need. Special action systems can also be implemented according to customer requirements.
