Honeywell L91B1050 Pressuretrol Controllers, Modulating, 5-150 PSI

Honeywell L91B1050 Pressuretrol Controllers are modulating pressure operating controls designed for liquid, air, and non-corrosive gases regulation. Suitable for use with steam, air, and non-combustible gases, or other fluids non-corrosive to the bellows material (phos-bronze for 300 psi models).

DO NOT use with combustible mediums or any substance chemically harmful to the bellows material (phos-bronze for 10-300 psi models, brass for other pressure range models).

Features:

• Has an adjustable proportioning (throttling) range to allow the selection of desired pressure control range.
• Large, easily read scaleplates in both U.S. customary (oz/sq. in., psi, or in. Hg) and metric (kPa, MPa, or mm Hg) units.
• Operating Range: 5 to 150 psi
• Proportioning (Throttling) Range at Midscale: 5 to 23 psi
• Maximum Surge Pressure: 225psi
