Bulletin 71.1:Y600A January 2010 Y600A Series Pressure Reducing Regulators W7095 Figure 1. Type Y600A Pressure Reducing Regulator Introduction Features Y600A Series direct-operated, spring-loaded regulators provide economical pressure-reducing control for a variety of residential, commercial, and industrial applications. • Precision Control at Low-Pressure Settings— The large diaphragm area provides more accurate control at low-pressure settings. The pitot tube of Types Y600A and Y600AR (Figure 2) regulators also creates a dynamic boost that helps provide greater capacity. The large diaphragm area provides more accurate control at low-pressure settings, and the pitot tube of the Type Y600A or Y600AR regulator also creates a dynamic boost that helps provide greater capacity. • Tamper-Resistant Adjustment—The closing cap and spring case (Figure 2) allow the installation of sealing wire to discourage or detect unauthorized adjustment of the pressure setting. • 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. D102575X012 The Type Y600A features internal registration. The Type Y600AR has internal registration and relief. The Type Y600AM uses external registration with a 1/2 NPT downstream control line connection and an O-ring stem seal. • Easy Conversion Between Types Y600A and Y600AM—The throat seal can be modified to either version. A new lower casing is not needed. www.fisherregulators.com

Bulletin 71.1:Y600A relief valve spring valve disk pusher post pipe plug orifice Type Y600AR with internal relief/internal pressure registration B2623 inlet pressure outlet pressure atmospheric pressure Figure 2. Y600A Series Operational Schematic (continued) Principle of Operations Refer to Figure 2. When downstream demand decreases, the pressure under the diaphragm increases. This pressure overcomes the regulator setting (which is set by a spring). Through the action of the pusher post assembly, the valve disk moves closer to the orifice and reduces gas flow. If demand downstream...

Capacity Information Tables 6 and 7 give the natural gas regulating capacities ofY600A Series regulators at selected inlet pressures and outlet pressure settings. Flows are in SCFH (60°F and 14.7 psia) of 0.6 specific gravity gas. To determine equivalent capacities for air, propane, butane, or nitrogen, multiply the Table 6 or 7 capacity by the following appropriate conversion factor: 0.775 for nitrogen. For gases of other specific gravities, multiply the given capacity by 0.775, and divide by the square root of the appropriate specific gravity. Then, if capacity is desired in normal cubic...
