Sweet Natural Gas

Speciﬁcation

Filtered to 100μ nominal. Free

of excessive moisture (< 7 lbs.

entrained H2O per 1.0 mmscf)

and liquid hydrocarbons.

If excessive moisture or hydrocarbon content is present, a

Filter-Dryer may be necessary. For adequate ﬁltration and

elimination of moisture, a Becker Model FD-1500 Filter-Dryer

should be installed. Refer to Becker FD-1500 literature to

determine if a Model FD-1500 Filter-Dryer is necessary.

Figure 2 - Becker RPDA Actuated Control Valves

A pressure control regulator station is shown here with Becker RPDA

actuators and T-Ball Control Valves. The RPDA actuators are equipped

with Becker VRP-CH Valve Regulator Pilots (VRP). The VRP is capable

of providing extremely accurate pressure control with fast response

necessary for power plant type applications. Additionally, note that

the VRP-CH pressure control pilots are equipped with Model VB-250

Volume Boosters to increase stroking speed. The primary regula-

tor is equipped with a QTCV-T2 Quiet Trim Control Valve to provide

decreased noise during operation. The monitor regulator is equipped

with a FPCV-T0 Full Port Control Valve that ensures bubble tight shut-

off with class VI shutoff.
