Gas pressure regulator PIDH 3/4

membranepistondome-loaded

Dome pressure regulators with integrated pilot regulators are characterised 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 fluctuations is reached with a balanced poppet. If the dome pressure regulator is used for the pressure control of gases, the dome pressure can controlled with the needle valves on the inlet pressure side. For the pressure regulation of liquids the Dome is filled externally with compressed air or nitrogen by means of a pilot pressure regulator. Special characteristics: The P.I.D. combines the advantages of a dome pressure regulator and a pilot regulator in just one complete and compact pressure regulator. This design is very space saving and easy to assamble and handle. The dome pressure regulator is used as a line pressure regulator. Without exchanging parts it is suitable for a large outlet pressure range. Independent of 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.
