New and Original Fisher 627-1217-29998(627-576) Self-Operated Pressure Reducing Regulator valve For Gas Burner 

FEATURES 
* Internal Relief Valve-Types 627R, 627LR, 627MR and 627BMR 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, 627MR and 627BMR Travel Stop-The internal relief valve still works if the disk or linkage fails. The pusher post (Figure 10) 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 11) 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 in locations with limited space (Figure 12). The regulator may be installed in any
position without affecting operation as long as the spring case vent is protected from the elements.
* Application Versatility-The different 627 Series constructions can be used as farm tap regulators, regulator-relief valves, monitoring regulators, slam-shut regulators or high-pressure industrial regulators.
* Extended Body Option-The Type 627 Long Body is available with same face-to-face dimensions as the Type 630 with threaded NPT end connections.
* Tamper-Resistant-An adjusting screw locknut and protective cap (Figure 2) is standard on all 627 Series regulators to discourage tampering with the pressure setting.
* Wide Range of Flow Capabilities-A selection of body sizes and orifice sizes is available to satisfy various flow requirements.
* Balanced Trim Option-The Type 627BM has a balanced trim design to enhance flow rates and inlet pressure ratings.
* Tight Shutoff Capability-A flat-faced disk of Nitrile (NBR), Nylon (PA) or Fluorocarbon (FKM) provides excellent shut-off capability
