The 1800PFM regulator has two pilot options: 1804 pilot covers a wide range of outlet pressures from 2-30 PSIG (138mbar - 2 Bar) and 1805 optimizes performance between 7WC and 2 PSIG (17 - 138mbar). Temperature range -20°F to +150°F (-30°C to 65°C). It maintains constant outlet pressure within ±1% absolute set pressure over a wide range of flow rates.
