Bulletin 71 2 627F February 2013 Type 627F Pilot Operated Pressure Reducing Regulator W5607 1 Figure 1 Type 627F Pressure Reducing Regulators Introduction The Type 627F pilot operated Type 6351F pilot pressure reducing regulator Figure 1 provides superior performance when used in pressure factor measurement fixed factor billing applications The Type 627F includes a factory installed Type 6351F pilot and has external registration that requires a downstream control line Features Accurate for Pressure Factor Measurement Applications Pilot action controls pressure to within 1 percent of the absolute outlet pressure psia setting at full valve disk travel resulting in higher capacity than could be obtained without a pilot This capability results in low pressure variations over broad flow ranges and inlet pressure ranges Easy to Maintain Trim parts can be replaced without removing the regulator body from the www fisherregulators com W5641 1 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 in locations with limited space The regulator may be installed in any position without affecting operation as long as the spring case vent is protected from the elements Tamper Resistant An adjusting scr
