Bulletin 71 1 627 March 2013 627 Series Pressure Reducing Regulators Introduction The 627 Series direct operated pressure reducing regulators Figure 1 are for low and high pressure systems These regulators can be used with natural air or a variety of other gases Performance characteristics vary according to construction see the Specifications section Features Internal Relief Valve Types 627R 627LR and 627MR regulators have an internal relief valve which in many cases eliminates the usual requirement for an external relief valve thereby reducing equipment and maintenance costs Refer to the Specifications section for performance data Types 627R 627LR and 627MR Travel Stop The internal relief valve still works if the disk or linkage fails The pusher post Figure 6 contacts the travel stop of the lever retainer and as the diaphragm continues to rise it opens the relief valve Relief Operation Indicator A rubber cap Figure 7 slipped on the vent assembly pops off when the relief valve opens indicating the relief valve has opened since the last inspection Easy to Maintain Trim parts can be replaced without removing the regulator body from the pipeline A two bolt connection between the body and diaphragm casing simplifies disassembly for maintenance Installation Adaptability The diaphragm case and or regulator body can be rotated in any of four positions to allow regulator installation
