These regulator are used for reducing the pressures of medical gasses from 30 bars to desired pipeline pressures. High pressure regulators sometimes gives fluctuating pressure values. Low pressure regulator are used for balancing the total output pressure.
All gas passages are made of brass and rubber material compatible with medical gases and the regulator is completed with an aluminum cover. There is a bolt that allows the pressure value to be adjusted and a counter nut that ensures that the pressure value is safe and high quality after adjustment. There are manometers to control the input and output pressure values of pressure regulators.
