WITT-Gasetechnik’s dome-loaded pressure regulator is impervious to system pressure and withdrawal fluctuations. A design modification to the integrated control pressure regulator ensures an almost complete compensation of supply pressure and outlet fluctuations. Thus, users can rely on constant conditions in the gas supply at any time. In contrast to spring-loaded pressure regulators, dome-loaded pressure regulators are operated by gas pressure. The “control gas” is monitored via a separate control pressure regulator. More detail at http://articles.sae.org/13620 .
