The 3/32" orifice size offers the ideal balance of flow and pressure management for industrial solenoid applications where tight shut-off and consistent cycling are non-negotiable

provided the switch is mounted according to the manufacturer's original orientation to prevent moisture accumulation in the diaphragm

Always verify the voltage requirements on the powerhead plate before installation to avoid electrical failure

you must always use the reset type specified by the manufacturer for your specific model to prevent dangerous cycling on a high-limit condition

it can be used in any 5k Ohm thermistor circuit requiring a 4-inch probe

Hydrotherm BM-8782 Aquastat Limit 30067439-890 The 3/32" orifice size offersThe Hydrotherm BM 8782 Aquastat Limit is a specialized immersion type temperature controller designed for precise fluid management in hydronic heating boilers. As a critical safety and operational component, this aquastat high limit switch monitors internal water temperatures to prevent overheating conditions that can lead to system fatigue or pressure relief valve discharge.
