Introduction
The 67C Series regulators are typically used to provide constantly controlled, reduced pressures to pneumatic andelectropneumatic controllers and other instruments. These direct-operated regulators are suitable for most air orgas applications. Other applications include providing reduced pressures to air chucks, air jets, and spray guns.

Principle of Operation (figure 2)
Downstream pressure is registered internally on thelower side of the diaphragm. When the downstreampressure is at or above the set pressure, the valve plugis held against the orifice and there is no flow throughthe regulator. When demand increases, downstreampressure drops slightly allowing the spring to extend,moving the stem down and the valve plug away fromthe orifice. This allows flow through the regulator.
Internal Relief (Types 67CR, 67CSR,67CFR, and 67CFSR)
If for some reason, outside of normal operatingconditions, the downstream pressure exceeds the setpoint of the regulator, the force created by thedownstream pressure will lift the diaphragm until thediaphragm is lifted off the relief seat. This allows flowthrough the token relief. The relief valve on theType 67CR, 67CSR, 67CFR, or 67CFSR is an elastomerplug that prevents leakage of air from the downstreamto atmosphere during normal operation, therebyconserving plant air.
Smart Bleed™ Airset
In some cases, it is desired to exhaust downstreampressure if inlet pressure is lost or drops below thesetpoint of the regulator. For example, if the regulator isinstalled on equipment that at times has no flowdemand but is expected to backflow on loss of inletpressure. The Type 67CFR can be ordered with theSmart Bleed™ option which includes an internal checkvalve for this application. During operation, if inletpressure is lost, or decreases below the setpoint of theregulator, the downstream pressure will back flowupstream through the regulator and check valve. Thisoption eliminates the need for a fixed bleed downstreamof the regulator, thereby conserving plant air.
Overpressure Protection
The 67C Series regulators have maximum outletpressure ratings that are lower than their maximuminlet pressure ratings. A pressure relieving or pressurelimiting device is needed if inlet pressure can exceedthe maximum outlet pressure rating. Refer to theCapacity Information section and the Wide-OpenCoefficients for Relief Valve Sizing in the Specifica-tions on page 3 to determine the required relief valvecapacity.
Type 67CR, 67CSR, 67CFR, and 67CFSR regulatorshave a low capacity internal relief valve for minor seat
leakage only. Other overpressure protection must beprovided if the maximum inlet pressure can exceed themaximum pressure rating of the downstream equipmentor exceeds maximum outlet pressure rating of theType 67CR, 67CSR, 67CFR, or 67CFSR regulator.
Capacity Information
Table 3 shows the air regulating capacities of the67C Series regulators at selected inlet pressures andoutlet pressure settings. Flows are shown in scfh(at 60°F and 14.7 psia) and in m³/h(n) (at 0°C and1,01325 bar) of air.
Note
The 67C Series regulators may be sizedfor 100% flow using capacities as shownin table 3. It is not necessary to reducepublished capacities.
To determine the equivalent capacities for other gases,multiply the table capacity by the following appropriateconversion factor: 1.29 for 0.6 specific gravity naturalgas, 0.810 for propane, 0.707 for butane, or 1.018 fornitrogen. For gases of other specific gravities, dividethe table capacities by the square root of the appropri-ate specific gravity. To find wide-open flow capacitiesfor relief sizing at any inlet pressure, perform one ofthe following procedures. Then, if necessary, convertusing the factors provided above.
For critical pressure drops (absolute outlet pressureequal to or less than one-half of absolute inlet pres-sure), use the following formula:
Q = (P1)(Cg)
For pressure drops lower than critical (absoluteoutlet pressure greater than one-half of absolute inletpressure), use the following formula:
Q 520GT
C P SIN g 1=⎛
⎝⎜⎜
⎞
⎠⎟⎟
34171 1C
PP
DEG∆
where,
Q = gas flow rate, scfhP1 = absolute inlet pressure, psia (P1 gauge + 14.7)Cg = gas sizing coefficientG = specific gravity of the gasT = absolute temperature of gas at inlet, °Rankine
C1 = flow coefficient (Cg ÷ Cv)∆P = pressure drop across the regulator, psi
Then, if capacity is desired in normal cubic meters perhour (at 0°C and 1,01325 bar), multiply scfh by 0.0268.
