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.
