Description
Maintain optimal pressure control with the Honeywell L91B1035 Modulating PressureTrol Controller, designed to dynamically regulate pressures between 0 and 15 psi in hydronic, steam, air, and non-corrosive gas systems. Part of Honeywell’s Series 90 Proportioning PressureTrol controllers, this model offers accurate, smooth control with adjustable differential settings, ideal for systems that require fine-tuned pressure variation.
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).
