When in use, pre-load pressure (differential pressure) is applied to the valves body; this means that they are always closed when in the normal position. The pre-load pressure (differential pressure) is always between 2-2.5bar above the maximal feed or medium pressure depending on the nominal diameters and elastomer involved. Depending on the nominal diameter involved the Pressure relief valves range of applied pressure is between 0-6bar.
Application area of Pressure Relief Valve
The Pressure relief valves main area of application is to be found in the bypasses of pumps for conveying waste water, sludge and other suspensions. However, they are also frequently used as regulating or relief valves in diverse installations, tanks or silos.
Function of Pressure Relief Valve
As soon as the maximal feed or medium pressure is exceeded because of restrictions in the pipeline or other blockages, the Pressure relief valve starts opening steadily and the excess pressure is able to circulate through the pump's bypass or the installation's pipeline. It is therefore able to protect diverse pumps and tanks from excess pressures and the overload of engines and materials arising as a result. Changes in control pressures can be monitored via integrated pressure switches.
