The 133 and 233 service regulators are versatile, large diaphragm-controlled regulators designed for commercial applications. Based on an original American design, they have been upgraded to meet the demanding requirements of German codes of practice, with built-in safety shutoff valve, integral creep relief valve, fire resistance, safety diaphragm and gas loss protection (R 133 only). The non- balanced valve design, makes these regulators mainly suitable for applications with limited inlet pressure variations
