Excellence in Pneumatics

 

 

Hafner-Pneumatik is the manufacturer of a complete range of high-quality pneumatic control valves made in Europe.

Our products are not only used in the general automation or the machine-building industries, but also in applications throughout the car, truck and process industries. Our customers enjoy the use of our valves because of their outstanding reliability offered at an extraordinary price/value ratio.

Our product line consists of solenoid valves, air pilot, manually and mechanically actuated valves, completed by pneumatic control systems. Our wide range of standard products covering sizes from M 5 to G 3/4″ is designed as a modular system, giving us the ability to develop and manufacture customer specific solutions in smaller numbers.

As a highly flexible company, we rapidly assimilate technical innovations which allows us to react quickly to the demands of an ever changing market.

Hafner-Pneumatik stands for over 30 years of knowledge and venture in the development of pneumatics. Manufacturing excellence, flexibility and customer responsiveness are the dominating elements of our corporate strategy.

The Design

 

 

By using high quality materials and an approved sealing system, we offer distinct advantages to our customers.
No compromises were made in the selection of materials. The bodies are made from anodised aluminium, the
spools from stainless steel and the manual overrides from brass.


Hafner sealing system

The major advantage of HAFNER's sealing concept is the low friction.
 

This advantage is based on the following technical features:


  • There is no deformation of the seal during assemblage of the valve - they are allowed to move independently within the brass cage. Without air pressure there is no contact pressure and, therefore, no friction. This construction also has consequences for the seals of the valves in use. When switching a 5/2 valve, only three of the five seals are exposed to pressure and applying friction to the spool.


  • This unique sealing design means that the contact pressure, and consequently the sealing effect, increases proportionally to the air pressure. If the air pressure is low, contact pressure of the seals and friction are minimised.


  • Even when pressure is high, due to the shape of the cage, there is only the minimal contact pressure applied to the sealing rings which is necessary to seal the valve, as shown in the drawing above.

 

These features offer you:


  • High durability and extended lifetime!


  • High flow combined with compact design!


  • High reliability of the valves!
