Johnson Controls P74AA-1 Pressure Control 321894-708 Efficiency Optimization: Reduces off-cycle heat

Efficiency Optimization: Reduces off-cycle heat loss by sealing the flue when the boiler is not firing

making it suitable for both atmospheric and pressurized vessels

utilizing its internal 8 to 13 psig spring

supporting a maximum inlet pressure of up to 60 psig

Johnson Controls P74AA-1 Pressure Control 321894-708 Efficiency Optimization: Reduces off-cycle heatThe Johnson Controls P74AA 1 is a robust differential pressure control designed primarily for monitoring lube oil pressure in high performance refrigeration compressors. This SPST switch is engineered to close on a decrease in pressure difference, providing a critical safety cut out to prevent mechanical failure. It features a wide adjustable range from 8 to 70 psi, with a manageable switch differential of 8 to 30 psi. Built for durability in
