Over-/under pressure valve

Over-/underpressure Valves


DCS is able to deliver the right solution for OUPVā€™s in every situation! For most situations, our two standard types of OUPVā€™s will be a perfect fit. For other situations, we also have very good alternatives to meet your requirements!
 
The biogas that is being produced inside your tank, has a certain pressure, measured in mBar. In standard situations, we take a pressure into account between -1,0 and +5,0 mBar. Our pressure valves make sure that the gas pressure inside your tank does not exceed the maximum pressure limit.
 
Our OUPVā€™s also have a very narrow flange connection (150 or 200 mm), which gives you the benefit of mounting the OUPVā€™s higher on your tank, so you can fill up your tank with slurry even higher!
