Description
The Honeywell L91A1052 Proportional Pressuretrol Controller is engineered for precise modulation of pressure in steam boilers, air systems, and non-corrosive gas applications. With an adjustable operating range from 5 to 150 psi and a fixed 5 psi differential, this controller ensures optimal performance and efficiency.
Features:
- Use with steam, air, noncombustible gases, or other fluids non-corrosive to the brass or phos-bronze (300 psi models) bellows.
- Do NOT use with combustible mediums or any medium chemically harmful to phos-bronze bellows (10-300 psi models) or brass bellows (all other pressure range models).
