 > Good morning. We are looking for relief valves. The relief valve we want will be used for plastics with the valve open between 2 and 3 bar. The size is 3mm to 5mm in diameter 12mm thick.

 2 and 3 bar is too low pressure and 12mm thick is too small, in my opinion, our products are not proper that specification. could you make questions clearly?
