2-6. PRESSURE REGULATING VALVE.
Isolation Valves (1, 2, and 3)
The skid mounted pressure regulating valve is installed where pressure is expected to exceed 225 psig
in the 6-inch hoseline. The valve is preset to release outlet pressure at a rate of 75 psig. Three hand
operated isolation valves control operation of the pressure regulating valve. All valves must be open
during normal operation. Closing the isolation valves shuts off the pressure regulator when a reduction
in hoseline pressure is not required.
