Trebur-Astheim, Hessen -- (SBWIRE) -- 01/08/2011 -- For industries it is essential to count on long-lasting and reliably working machines. In most of the cases machines have to be secured from breaking down and fluctuating working pressures. Even slightly deviations from normal conditions can cause long and expensive downtimes. The company AKO Armaturen & Separations GmbH located in Trebur close to Frankfurt a. M. develops and manufactures high pressure relief valves which are installed to prevent machine failures. AKO pressure relief valves are usually installed in pipes of food and paper industry.

AKO has been producing high quality armatures for 25 years already. Thanks to past experiences and intensive

customer contacts AKO knows the various important standards and requests of customers in this industry. Pressure relief valves are to be found in a variety of different more or less complex industrial plants. Moreover the construction of an AKO pressure relief valve is simple and absolute efficient. Each pressure relief valve is made up of a pressure relief device and a pinch valve unit. The former is available as type LV and LNV and the latter as VMF/VM or VF. Thanks to a wide diversity of combinations the pressure relief valve can be set up in many different application areas. In addition to that AKO always tries to realize special requirements and welcomes requests for custom-made products.

The operating mode of a pressure relief valve is easy and quickly explained. The valve of the armature is subject to a charging pressure. This charging pressure has to be 2 to 2.5 bars higher than the pressure of the particular material piped in the tubes. That is why the pressure relief valve is in its initial position always closed. The soon the pressure inside the pipes increases the valve opens automatically and hence balances the excess pressure. Depending on the construction of the pressure relief valve and choice of the material this armature can be installed in areas with pressures up to 6 bars and a temperature of up to 100°C.
