Dome pressure regulators are characterized by an accurate regulation and a large throughput. The dome pressure regulator works according to the principle of the pressure balance between dome pressure and outlet pressure. A large independence from fluctuation of the inlet pressure is reached with a balanced poppet. If the dome pressure regulator is used for the pressure control of gases, the dome pressure can be controlled by needle valves. For the pressure regulation of liquids and aggressive gases, the dome can be filled
with compressed air or nitrogen externally, by means of a pilot pressure regulator.
The dome pressure regulator is used as a line pressure regulator. Without exchanging parts it is suitable for a large outlet pressure range. Dependent on the used material, the pressure regulator is applicable for different gases and liquids. We urgently recommend the connection of a fine filter with max. 40 μ at the inlet of the pressure regulator. Subsequent components and plant components must be protected by separate safety valves.
