Download "Fischer Series-Air Regulators-datasheet These direct-operated regulators are suitable for most air or gas applications. Other applications include providing reduced pressures to air chucks, air jets, and spray guns. Recommended for deadend service. Filter mands of digital instrumentation. Optional stainless steel capacities can be used with confidence. Table 1. Silicone is not compatible with hydrocarbon gas. Environmental limits may apply. Other overpressure protection must be Principle of Operation figure 2 provided if the maximum inlet pressure can exceed the Downstream pressure is registered internally on the maximum pressure rating of the downstream equipment lower side of the diaphragm.
When demand increases, downstream Capacity Information pressure drops slightly allowing the spring to extend, moving the stem down and the valve plug away from Table 3 shows the air regulating capacities of the the orifice. This allows flow through the regulator. It is not necessary to reduce diaphragm is lifted off the relief seat.
This allows flow published capacities. The relief valve on the Type 67CR, 67CSR, 67CFR, or 67CFSR is an elastomer To determine the equivalent capacities for other gases, plug that prevents leakage of air from the downstream multiply the table capacity by the following appropriate to atmosphere during normal operation, thereby conversion factor: 1.
To find wide-open flow capacities In some cases, it is desired to exhaust downstream for relief sizing at any inlet pressure, perform one of pressure if inlet pressure is lost or drops below the the following procedures.
Then, if necessary, convert setpoint of the regulator. For example, if the regulator is using the factors provided above. This outlet pressure greater than one-half of absolute inlet option eliminates the need for a fixed bleed downstream pressure , use the following formula: of the regulator, thereby conserving plant air. A single gauge typically shows loading Regulators figure 4 pressure to the control valve.
For more information see bulletin The Series panel-mounted loading regulators are compact, rugged units used primarily for manually loading pressure-balanced gas regulators and providing Ordering Information manual control for diaphragm actuator control valves.
Applications include remote control of gas pressure to When ordering, complete the Ordering Guide on page burners in refineries, power plants, and various Refer to the Specifications on page 3.
Review the process furnaces. Specify line, each having one 67C Series pressure regulator your choice whenever a selection is offered. Figure 3. Spacer Dimensions and Installation Schematic 10 Bulletin Need for Extremely Fast Response?
