The American Meter Series 1800CPB2 pressure regulator is designed for natural gas applications and features a compact, lightweight design for fast, easy installation.
The 1800CPB2 regulator consists of a main regulator and a pilot regulator. It is a downstream bleed, pressure loaded regulator, designed to provide stability of operation for precise and constant outlet metering pressure control.
The regulator is capable of handling varying inlet pressures up to 125 PSIG while controlling a set constant outlet pressure (1 to 30 PSIG) within ¡Ó1% of the absolute set pressure over a wide range of flow rates.
The main regulator is normally closed, furnished with one spring (for all outlet pressures) to close the regulator if loading pressure fails. The pilot regulator outlet line mounts to the main regulator vent and connection tubing brings the main regulator inlet pressure to the pilot regulator inlet.
The pilot regulator (one spring controls all outlet pressures from 1 PSIG to 30 PSIG) is used to load pressure on the diaphragm of the main regulator. Adjustment of the pilot regulator depends upon the inlet pressure and outlet pressure range desired. The pilot regulator using upstream pressure as its supply, reduces this pressure to a predetermined value and then loads the main regulator diaphragm. The loading pressure overcomes the force of the main regulator spring causing the main regulator to open.
Overpressure Shut-Off Regulators
Model 1883CPB2 regulators are compact units designed to regulate line pressure and to provide protection against any downstream overpressure.
Rugged, Compact OPSO Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up.
Adjustable Overpressure Shut-Off Pressure is adjustable via the overpressure shut-off adjustment screw to settings from 5 to 15 PSIG and 15 to 40 PSIG depending on spring selected.
