Butterfly dampers are normally associated with flow control in ducts, but there are numerous applications in which they are used successfully in the inlet or intake of industrial fans due to their versatility and great ability to adapt to various sizes, pressures, temperatures, etc. 

The different designs of this valve allow it to be adapted to the tightness required by the customer. There is not only the possibility of having the valve open or closed, but also in different intermediate positions.

Thanks to their personalized design and the use of the most appropriate materials, these valves are adjusted to the final working conditions depending on the needs of the installation, high temperature, corrosivity, etc.

Depending on the sector, the working conditions, the type of construction and the valve materials, we adapt to provide the best service at a competitive price. Our partner normally uses the valves in installations together with industrial centrifugal and axial fans, but they can also be installed at any point in the installation where
be necessary. 

MANUFACTURING

Our associate has a robust manufacturing, complying with the quality standards set by the company to guarantee a functional, durable and quality product.

SUPERFICIAL TREATMENTS

Depending on the application, we select a specific type of primer and finish that we recommend to our clients for each project. We also apply special high temperature paints up to 500ºC. We carry out shot blasting and quality controls, such as measurements of the thickness and adhesion of the paint.

ASSEMBLY

We offer assembly services for all our products, including valves. We carry out both assemblies in our facilities and in those of the client, providing total comfort and always guaranteeing maximum safety.

WORKING CONDITIONS

Our valves are designed to withstand the following

terms: 

– Maximum temperature: 600ºC

– Maximum pressure: 2 bar

It should be noted that these characteristics may vary

depending on the diameter of the valves.

DRIVES

These valves can be operated by all types of actuators: manual, electric, pneumatic and hydraulic. There is also the option of implementing special regulation systems under customer specification.

MATERIALS

Our associate manufactures with different materials depending on the operating conditions of the fluid. To determine the materials to be used, it is important to take into account the characteristics of the fluid and its composition. 

The materials we usually work with are:

S275JR, AISI-304L, AISI-316L, 16Mo3, HARDOX-400 …

For fluids with abrasive particles we use anti-wear materials to make the valves more durable. We select the most suitable material for the operating conditions, or we manufacture under the indications or regulations of the customer’s installation.

DOCUMENTATION

In the documentation that we send to our clients, we show the general dimensions of the assembly with its connection flanges.
